Acetaldehyde It is a compound produced during fermentation. When clearly present, it often creates a sensation. the smell and taste of unripe green apples (like a "green apple").

In many cases, acetaldehyde is a sign that the beer is still "immature" (not yet stable), or that the fermentation/aging process has not been long enough for the flavor to become well-rounded and clean.

Acid rest It is an early rest step in the mashing process, usually around 35°C, in order to help lower pH of a mixture of malt and water.

In short: The "right" pH helps enzymes function more stably, thereby supporting sugar production and contributing to a cleaner, more balanced beer taste.

Acrospire It is the sprout (germination) that grows when barley grains are allowed to germinate during the malting process.

This is a "sign" that the grain has begun to transform, activating the enzyme system necessary to later convert starch into sugar when brewing beer.

Adjunct It is an ingredient used to make fermented sugar. not malted barley, which are added when brewing beer. The most common is rice and corn, In addition, it could be honey, syrup, or other sources of carbohydrates.

Adjunct is commonly used in beer making. Lighter, drier, and easier to drink. Or they help control costs. Therefore, they are commonly found in large-scale production light lager models.

Age is the process of introducing oxygen. word (This refers to beer that has not yet been fermented, essentially meaning "unfermented beer"). Oxygen is essential for... yeast (Yeast) in the initial stage to ensure the yeast is healthy and ferments strongly and stably.

Important note: if oxygen gets into the beer after fermentation is complete, Beer is easily oxidation, creating a paper/cardboard smell and a feeling of being "old" or "lifeless".

Alcohol Beer mainly contains ethanol (Food-grade alcohol) is produced when yeast converts sugar into alcohol and CO₂ gas. Depending on the style, beer can be very light or very strong.

Most craft beers are usually around this price. 5–6% ABV, While some stronger lines can reach double digits (10%+), giving a warmer and thicker sensation when drunk.

ABV It is the most common indicator for describing the strength of beer, showing percentage of alcohol by volume.

In short: the higher the ABV, the warmer and "heavier" the beer usually feels. However, strength doesn't always mean "difficult to drink," as it also depends on the malt balance, sweetness, and bitterness.

ABW measure alcohol content according to weight in a volume of beer. This indicator is usually lower ABV and less frequently seen on modern beer labels.

If you see ABW on the label, remember: for the same beer, ABV will always give a "larger" number than ABW.

1. In the flavor description, Colin just a feeling warm Because of alcohol and higher alcohols, it may evoke a "spicy" or slightly "vinous" feeling.

2. Beers with higher ABV (Average Value) generally offer better quality. feeling of fullness in the mouth It is more potent, and the alcoholic notes are also more likely to stand out in the aroma and taste.

Ale These are beers fermented using "top-fermenting" yeast, typically at warmer temperatures than lager.

A common misconception: Ale doesn't necessarily mean a stronger beer.. "Ale" refers to the fermentation process and flavor characteristics, not necessarily the alcohol content.

Ale yeast (most commonly encountered is Saccharomyces cerevisiae) is a type of yeast that works best in the range 15–21°C, and often produces more flavor compounds.

Therefore, many ale beers tend to have a more "fruity/floral" aroma or richer layers of flavor compared to very clean lagers.

All extract beer It is beer brewed entirely from malt extract (malt extract) instead of using whole malt grains for mashing.

This method simplifies the brewing process, making it suitable for home brewers or quick test batches.

All-malt beer It is beer brewed entirely from barley malt, without using adjunct, sugar, or other fermentation starters.

Simply put: the entire "foundation" of beer comes from malt, so the malt flavor is usually more pronounced and has more depth (depending on the style).

Alpha acid is an important group of compounds in hops, contributing to the creation bitter of beer. When boiled, alpha acids are converted into a more effective bittering form.

Over time, alpha acids can oxidize and bitterness can decrease, so the quality and storage of hops directly affect the "sharpness" of the beer.

Alpha amylase and beta amylase These are two key enzymes in the mash process, helping to convert the starch in malt into sugar.

In short: different mash temperatures will "prioritize" each type of enzyme, thereby creating different sugar ratios, affecting the beer. dry or sweet, light or full.

Apparent attenuation This is a way to estimate how much yeast has "consumed" the sugar in the wort and converted it into alcohol/CO₂. This indicator is usually expressed as a percentage.

Simply put: the higher the attenuation, the more typical the beer. dried and less sweet; lower attenuation often leaves a lingering sensation. sweet and full than.

Aromatic hops Hops are added at the final stage of boiling or in subsequent steps to enhance flavor. fragrance rather than creating bitterness.

In short: adding hops later in the day usually helps the beer develop citrus, floral, fruity, or resinous aromas (depending on the hop variety), rather than just increasing bitterness.

Astringency it is a feeling dry, bitter, and astringent.“ in the mouth, similar to when drinking tea that's too bitter. The cause is often related to tannins, oxidized phenolic compounds, or components that give a "stale" sensation in beer.

When the astringency is too strong, the beer can easily be perceived as "dry and harsh," causing a slight contraction in the mouth and a less smooth aftertaste.

Attenuation This refers to the degree of decrease in the density of the wort as yeast consumes sugar and produces alcohol and CO₂ during fermentation.

You can think of attenuation as the "level of completion" of fermentation, and it directly affects the beer's dry/sweet taste and light/full feel.

Automination This is the phenomenon of dead yeast breaking down, which can produce undesirable odors such as rubber, vegetable or an unpleasant "alcohol smell.".

This usually happens when beer is exposed to dead yeast for too long, or when brewing/storage conditions are unsuitable.

Barley Barley is the most important base ingredient in brewing. When processed into malt, barley provides the sugars that yeast converts into alcohol, creating the main flavor profile of beer.

It can be said that barley malt is the "skeleton" that gives beer its body, flavor, and depth.

Barrel There are two common interpretations in the world of beer.

- First, this is unit of measurement In the US: 1 barrel is equivalent to approximately 117 liters.

- Secondly, barrel is wooden crate Used for aging beer. Beer aged in barrels typically absorbs aromas from the oak wood and traces of previously stored spirits, resulting in a warmer, deeper, and more complex character.

Beta acids These are a group of naturally occurring compounds found in hops. They don't directly contribute to the bitterness, but they help stabilize and preserve the beer's flavor over time.

Bitterness The bitterness of beer comes primarily from the hops. This is a defining factor in its style, especially for types like IPAs.

A balanced bitterness makes beer fresh, clean, and easy to drink. Conversely, a harsh, dry bitterness often makes beer less smooth and quickly tires the mouth.

BU IBU is another term used to estimate the bitterness level of beer. This number helps drinkers visualize whether the beer is mild or intensely bitter.

Bittering hops Hops are added early in the brewing process. The main purpose is to create a base bitterness for the beer.

The longer hops are brewed, the more bitter they become, while their aroma diminishes.

BJCP It is a non-profit organization dedicated to developing standards for evaluating beer styles and training tasting judges.

In competitions and professional literature, the term "BJCP standard" is often used to describe what a beer should taste and feel like.

Blending It is a technique of blending different batches of beer to create a more balanced or richer flavor.

This method is commonly found in sour beers, barrel-aged beers, or craft beers that emphasize fine-tuning.

Body It's the sensation of the beer's thickness in your mouth. It answers the question: Is this beer light and easy to swallow, or full-bodied and coating the mouth?

The body is influenced by the remaining sugar content, alcohol level, and brewing method.

Boiling This is the boiling step in the brewing process. This is when hops are added to give the beer its bitterness, flavor, and aroma.

Boiling also helps eliminate unwanted odors, purifies the cooking liquid, and terminates enzyme activity.

Bomber It's a large bottle of beer, approximately 650 ml, which was once very popular in the craft beer scene.

Bottle sealing This is a method of creating natural carbonation right in the bottle, by adding yeast and a small amount of sugar after bottling.

Beer brewed in this way typically has a smooth fizz and a "live" feel, sometimes with natural yeast sediment.

Bottom fermentation This is a type of fermentation where the yeast tends to settle to the bottom. This is characteristic of lager varieties.

Beer fermented in this way typically has a clean, crisp feel and less yeasty odor.

Brett It is a type of yeast that produces very "wild" flavors: it can evoke the scent of leather, old wood, dried grass, or a slightly sour sensation.

These notes can be very appealing in the right beers, but they can also be considered a flaw if they appear in the wrong place.

Brewers Association It is a major representative organization for the craft beer industry in the US, regularly publishing industry data, standards, and trend reports.

Brewpub It is a restaurant or bar model where beer is brewed on-site and most of the beer is sold at the location.

Brewer It is the brewing pot, where the wort is boiled and hops are added during the brewing process.

Unfold It is a stopper used to seal old-fashioned wooden barrels or kegs, helping to keep beer from coming into contact with outside air.

Blow hole It's the hole in the barrel where the beer is poured in and then sealed with a bung.

Stunted This term describes a mild sulfurous odor, often associated with mineral characteristics in some beers.

Byproducts These are compounds produced during the brewing and fermentation process. Some compounds enhance the flavor of beer, while others cause undesirable tastes and odors.

Calcium carbonate, Chalk, also known as mineral, is a common mineral found in water. In brewing, it is sometimes added to regulate calcium and carbonate levels.

This helps control the balance of the brewing water, which indirectly affects the feel, dryness, and overall structure of the beer.

Calcium sulfate, Gypsum, commonly known as gypsum, is a familiar mineral in water treatment for beer brewing.

When used appropriately, calcium sulfate helps to highlight the dry and sharp flavors of beer, making it particularly suitable for styles that emphasize hops.

Carbohydrates These are a group of organic compounds including sugars and starches. They serve as the "food source" for yeast to convert into alcohol and gas during the fermentation process.

The amount and type of carbohydrates remaining after fermentation will directly affect the sweetness, fullness, and smoothness of the beer.

Carbon dioxide It is a naturally occurring gas produced when yeast ferments sugar. This is what creates the foam and carbonation in beer.

CO₂ not only creates the effervescence but also affects how the beer spreads in the mouth and the overall flavor perception.

1. Carbonation Carbonation is the process of introducing CO₂ gas into beer to create carbonation. Beer can be carbonated in several different ways.

2. It is possible to retain the naturally produced carbonation during fermentation, inject CO₂ directly, or allow the beer to ferment again in the bottle (often called bottle conditioning).

3. The level of carbonation strongly influences the sensation of freshness, lightness, and how the beer "touches" the tongue when drunk.

Carboy A large vessel (usually made of glass or plastic) used for fermenting or storing beer, especially popular among home brewers.

Caryophyllene It is a natural essential oil found in hops. This compound contributes to the slightly spicy, herbal, or woody notes of the hops.

Depending on the hop variety and how it's used, caryophyllene can give beer more complexity and character.

Cash A beer container, shaped like a barrel. Traditionally made of wood, but nowadays more commonly made of stainless steel or aluminum.

Cask is often associated with beer styles that are served fresh, with light carbonation and a smooth feel.

Cash conditioning This is the process of allowing unfiltered and unpasteurized beer to continue to mature in a cask at a cool temperature.

This method allows the beer to develop its natural carbonation and retain the "lively" feel often found in traditional English beers.

Cellular It involves storing beer at a controlled temperature so that it can continue to mature over time.

Some beers become rounder, smoother, and more complex when properly cellared.

Chill haze This phenomenon occurs when beer becomes cloudy upon cooling. This is due to proteins and tannins combining at low temperatures.

This is primarily an aesthetic issue and usually doesn't significantly affect the taste.

Closed fermentation It is fermentation in a sealed environment, limiting contact with air.

This method helps reduce the risk of contamination and oxidation, keeping the beer cleaner and more stable.

Monthly ranking This is the phenomenon of proteins and tannins precipitating when a cooking liquid is rapidly cooled after boiling.

This process helps to make the beer clearer and reduces the risk of developing unwanted flavors.

Color The color of beer comes primarily from the type of malt used. The darker the malt is roasted or dried, the darker the beer's color.

While color may suggest style to some extent, it doesn't directly reflect the alcohol content, fullness, or calorie count of a beer.

Notification This is the resting and refining phase for the beer after the primary fermentation.

This stage helps to round out the flavor and limit the formation of unwanted odors.

Contract brewing This is a model in which a beer brand hires another brewery to produce beer for them.

The client typically focuses on branding, sales, and distribution, while the brewing and packaging are handled by the partner brewery.

Craft brewery, According to the Brewers Association's definition, a brewery is one that simultaneously meets three criteria: small scale, independence and actually brewing beer directly.

1. Small scale This means that the annual output does not exceed 6 million barrels, This is equivalent to approximately 31 TP3T of the total annual beer consumption in the United States. This criterion is intended to differentiate craft breweries from mass-produced beer factories.

2. Independent meaning not more 25% ownership or control They belong to large beverage corporations, not craft breweries. This helps ensure that breweries maintain their autonomy and creativity.

3. Actually, it's a brewery. That means the brewery has a legal license and beer production, It's not just a brand that hires other people to do all the cooking.

In short, craft breweries are breweries that produce beer. Small but serious, independence and real cooking, not belonging to industrial beer corporations.

Decoration mash It is a brewing method in which the brewer extracts part mash, Bring that portion to a boil, then return it to the main pot to raise the temperature of the entire mash.

This method is commonly used. 1–3 times In a mash-making process, and often associated with traditional styles like Central European lager, the result is typically a beer with a distinct malt depth, a bolder feel, and a more "mature" character.

Degrees Plato It is a scale for measuring the density of the cooking liquid, representing Percentage of extract by weight.

For example: 12°P This means that in 100 grams of the decoction there are approximately 12 grams of dissolved substance.This scale is commonly used in brewing lager and European-style restaurants.

Extrin are a group of complex carbohydrates not fermented.They form when starch is partially broken down during the mash process.

Dextrin contributes to body and a full-bodied feel to the beer. Some dextrin remains in the finished beer, creating a slight malty sweetness even though the beer isn't actually sweet.

Diacetyl It is a volatile compound produced by yeast, often with a similar smell and taste. butter, caramel, or butterscotch.

At the level very low, Diacetyl is accepted (even featured) in some traditional styles such as English Ale, Czech Pilsner, or Oktoberfest. However, at higher levels, diacetyl is often considered a off-flavor.

Diastatic This term refers to the enzymes produced when barley grains begin to germinate.

These enzymes are responsible for converting starch into sugar, providing food for the yeast during fermentation. In short, without diastatic activity, the brewing process cannot occur properly.

DMS It is a sulfur compound that can be present in beer. At certain levels very low, DMS has a slightly sweet aroma, which is acceptable in some lager varieties.

At higher levels, DMS produces odors. boiled vegetables,Often described as resembling boiled corn or celery. Boiling vigorously enough and cooling properly helps limit DMS.

Draught beer Beer is beer that is poured directly from kegs, casks, or serving tanks, instead of from bottles or cans.

Beer drunk from a growler shortly after bottling is sometimes also considered draught beer. The draught experience depends heavily on the pouring system and hygiene.

Dry Hopping This is a technique of adding hops after boiling or during/after fermentation to increase... fragrance Add it to the beer without significantly increasing the bitterness.

Hops can be added at various stages, from the whirlpool stage to primary or secondary fermentation, helping to give the beer more pronounced citrus, fruity, or resinous flavors.

Dual-ended hops Hops can be used to create both bitter just created fragrance.

This type of hop gives brewers more flexibility during the brewing process, making it particularly suitable for beer styles that strike a balance between bitterness and aroma.

Endosperm This is the starchy "core" inside the barley grain. This is the raw material used to create sugar during the mashing process.

When brewing beer, a key objective is to break down the endosperm structure so that enzymes can easily convert starch into sugar for yeast to use.

Essential hop oils These are the natural essential oils in hops, which are primarily responsible for aroma and flavor of beer.

The method and timing of adding hops will determine the amount of essential oils retained, thereby creating aroma notes such as citrus, fruity, herbal, or resinous.

Esters These are volatile odor compounds formed during fermentation when organic acids react with alcohols.

Esters often produce odors. fruit such as bananas, apples, pears, or peaches, and are prominent in many ale varieties.

Ethanol Ethyl alcohol is the main, colorless alcoholic component of beer.

This is a direct result of the process of yeast converting sugar into alcohol, and is what creates the warming sensation when drinking beer.

Export This term refers to beers brewed specifically for export.

Historically, "export" beers often had a slightly higher alcohol content or a firmer structure to withstand long-distance transportation.

Farnesome It is an essential oil found in hops, contributing to the light, fresh, and slightly herbal aroma notes.

Fermentable sugars These are types of sugars that yeast can "eat," thereby producing enzymes. ethanol and CO₂.

The more sugar that ferments, the drier and less sweet the beer will be.

Fermentation It is the process by which enzymes convert sugar into... alcohol and CO₂ gas.

There are two main types of fermentation in brewing: floating fermentation (create ale) and submerged fermentation (to create lager). The fermentation method strongly influences the flavor and texture of the beer.

Fermentation lock It is a one-way valve attached to the fermentation tank.

It allows CO₂ to escape while preventing air, bacteria, and wild yeast from entering, ensuring a safe fermentation process.

Filtration This is the process of filtering beer to remove suspended solids such as yeast or protein.

Filtered beer is usually clearer and more consistent, but it can sometimes lose some of its natural flavor.

Final gravity It is the specific gravity of beer when the fermentation process is complete.

This indicator helps the brewer know how dry the beer is and estimate the actual alcohol content.

Finding It is the process of adding clarifying agents to beer to draw the sediment to the bottom.

The goal is to make the beer clearer, not to change its taste.

Flocculation It is the phenomenon where particles (especially yeast) clump together and settle to the ground.

The flocculation ability of yeast affects the clarity of the beer and the rate of fermentation completion.

Forced carbonation Carbonation is created by pumping CO₂ directly into beer in a sealed tank.

This method is fast and easy to control, and is commonly used in large-scale production.

Fresh Hopping It is the practice of using freshly harvested, undried hops to brew beer.

This technique produces a fresh, green, and very "seasonal" aroma, distinctly different from conventionally processed hops.

Fusel alcohol These are a group of heavy alcohols, usually produced during fermentation in excessively high temperature.

They have a pungent, paint- or solvent-like smell and are often considered a fault. Fusel alcohol is also a common cause of headaches after drinking.

Germination It is the process by which barley grains germinate, producing rootlets and sprouts.

This is a crucial step to activate the enzymes necessary for the brewing process.

Grainy It is a term that describes a smell or taste similar to raw or uncooked cereal.

This feeling is sometimes considered crude if it's not presented in the right style.

Grit It is a mixture of malt and ground grains, ready for the mashing step.

Growler It's a takeaway beer container, commonly available in various capacities. 1.9 liters (64 oz) or approximately 2 liters.

Growler is often used to buy draft beer to take home, but it should be consumed soon after opening to maintain its best flavor.

Gruit It is a traditional herbal blend that was once used to add bitterness and flavor to beer before hops became popular.

Beer brewed in this style is often called Gruit ale, and it has a very historical and distinctive character.

Air pump It is a manual beer cask dispenser that does not use compressed CO₂ gas.

Thanks to this pouring method, the beer usually has a light fizz, a smoother and more natural feel, which is very characteristic of traditional English pubs.

Head reception This refers to the beer's ability to retain foam. This indicator is usually measured by Time (in seconds) to a foam layer about 2.5 cm (1 inch) deflate.

Beers with good head retention tend to have a fresher, fuller mouthfeel and look more appealing when drunk.

Heat exchanger It is a device used to rapidly cool hot cooking liquid before fermentation.

Rapid cooling reduces the risk of contamination and creates ideal conditions for yeast activity.

Homebuilding Brewing beer at home involves both technical skill and personal creativity.

In the US, homebrewing was legalized on [date]. 01/02/1979.The law allows each person to cook a maximum of 10 dishes. 100 gallons/year, or 200 gallons/year For households with two or more adults.

Hops Hops are perennial climbing plants, of which only female flower Hops are used in brewing beer. They provide bitterness, aroma, and help inhibit bacterial growth.

Hops can be added at various times: at the beginning (to add bitterness), in the middle (to add flavor), at the end or after brewing (to add aroma). Currently, there are... over 100 varieties of hops It is grown all over the world.

Hopping It is the act of adding hops to the brewed liquid or fermented beer.

The timing of the hopping determines whether the beer will lean towards bitterness, hop flavor, or aroma.

Hot break It is the phenomenon of proteins and tannins clumping together during the boiling process of a cooking liquid.

This process helps to make the beer clearer and reduces the risk of developing unwanted flavors.

Humulene It is an important essential oil in hops, creating herbal, woody, and slightly spicy notes.

Husk It is the dry outer layer of a grain.

In brewing, husk helps create a natural filter when separating the liquid from the grain residue.

Harmonica It is a glass instrument used to measure the density of a liquid relative to water.

In brewing, a hydrometer helps estimate the sugar content, dryness, and alcohol content of the beer.

Immersion chiller It is a device for cooling the brewing liquid, usually made of copper, and is immersed directly into the hot liquid before fermentation.

Infusion mash It is a mashing method that involves adding hot water at different temperatures to achieve the desired temperature.

This is a common, simple, and widely used method in modern brewing.

Incidental It is the act of introducing microorganisms (usually yeasts or lactobacillus) into a suitable environment for them to grow.

IBU It is a unit of measurement for the bitterness level of beer, based on the amount of bitter compounds from hops.

Light beers typically fall within the range. 5–10 IBU, while dark IPA can reach 50–70 IBU or higher.

Irish moss It is a natural clarifying agent extracted from seaweed.

It helps proteins precipitate during boiling, resulting in clearer and cleaner beer.

Isinglass It is a gelatin-like clarifying agent, traditionally extracted from fish bladders.

It helps to draw yeast and sediment down, making the beer clearer and more stable.

Keg It is a metal tank used to store, transport, and serve beer under pressure.

In the US, common sizes include: ½ barrel = 15.5 gallons, ¼ barrel = 7.75 gallons, 1/6 barrel = 5.23 gallons.

Kinning Malt drying is the process of drying malt to stop germination and to impart flavor and color to the malt.

The temperature and drying time determine whether the malt will be light or dark, which directly affects the color and aroma of the beer.

Kraeusen It is a thick layer of foam that appears on the surface of the cooking liquid during the fermentation process.

This term also refers to the technique of adding a quantity of unfermented liquid to already fermented beer to create a second natural carbonation.

Lace These are the streaks of foam that remain on the sides of the glass after drinking beer.

A beautiful lace layer usually indicates that the beer has good protein and maintains a stable foam.

Lactobacillus These are bacteria capable of converting sugar into lactic acid.

In most cases, it is considered to spoil beer, but in sour varieties, lactobacillus is intentionally used to create a pleasant sour taste.

Lager These are beers fermented using bottom-fermenting yeast at low temperatures.

Lager typically has a clean, crisp feel and is easy to drink.

Lager yeast works well in the range 7–13°C and often produce mild sulfur compounds.

Lagering It is the process of brewing beer at near-zero temperatures. 0°C during the period from from a few weeks to a few years.

This process helps make the beer clearer, cleaner, and more well-rounded in flavor.

Large brewery, as defined by the Brewers Association, is a brewery whose production exceeds 5% 6 million barrels/year.

Lauter tun It is a device used to separate the sweetened liquid from the grain residue after mashing.

Lautering It is the process of filtering and separating the liquid from the grain residue.

Hotels Truck This is the phenomenon where beer changes in smell when exposed to light, especially UV rays.

Beer that has been lightstruck typically has a very recognizable "skunk" smell, and is often found in clear or blue bottles.

Liquor In brewing, it refers to the liquid used to make beer.

The mineral content of water strongly influences the style and feel of beer.

Lovibond It is a color scale for malt and sometimes for beer.

The higher the Lovibond number, the darker the malt's color and the more pronounced the roasted aroma.

Magnum bottle is a large-capacity bottle 1.5 liters.This size is commonly found in "special release" or special occasion bottled beers.

Malt This is barley that has been processed using the malting method: soaking in water, controlled germination, and then drying to stop germination.

The goal of malting is to create enzymes and "open the way" for the starch in the grain to be easily converted into sugar during the mashing process. Malt also provides the base color and flavor (bread, caramel, roasted, etc.) for beer.

Malt softened is a concentrated malt form syrup or dry powder, used to brew beer faster and more conveniently.

This is a popular choice for homebrew beginners because it reduces many technical steps, but still produces a consistent beer if used correctly.

Maltose It is the most common fermentable sugar in brewing. It is the "main food" for yeast to produce alcohol and CO₂ gas.

Mash It is a mixture of ground malt (and possibly other grains) mixed with hot water.

After mash, the brewer will filter out the sweet, sugar-rich liquid, called the mash. soup (wort), to be boiled and fermented.

Mash tun This is the pot/container used to make mash, where the ground malt is soaked and kept warm to convert the starch into sugar.

Mashing It is the process of mixing ground malt with hot water so that enzymes can convert the starch into... fermented sugar and a portion of non-fermentable carbohydrates (which help create the body and maintain the foam).

Masing also carries color and flavor from the malt into the brew, while helping to reduce components that can cause cloudiness. This process is usually lengthy. a few hours.

Mash out This is the step of raising the mash temperature to approximately 170°F (approximately) 77°C).

The goal is to stop enzyme activity, prevent further starch conversion, and facilitate a smoother filtration process during cooking.

MBAA The Master Brewers Association of the Americas is a professional association founded in 1970. 1887, with the aim of promoting and enhancing expertise in the field of brewing and malt production.

Microbrewery, According to the Brewers Association definition, a brewery with a production volume below 2% is a brewery that produces less than 2% of its target. 15,000 barrels/year, and there is at least 75% amount of beer sold outside Off-site cooking location.

In short: microbreweries are small in scale, but tend to distribute their products to the market rather than just selling on-site like brewpubs.

Milling This step involves grinding the malt into a grit to facilitate sugar extraction during mashing. The starch core needs to be broken down, but not into a fine powder like flour.

It is important that the husk is kept relatively intact, as it will later act as a natural "filter" during lautering.

Mod Notification This refers to the degree of physical and chemical transformation of barley during the malting process, particularly related to enzyme formation and making the grain structure "easier to handle" during mashing.

The degree of modification is usually assessed based on the development of the acrospire. Good modification results in easier mashing, better extraction, and cleaner, more stable beer.

Modified malts This refers to malt that has undergone a certain degree of "internal breakdown" during the germination process.

The better the malt is "modified," the easier it is to mash and the more consistent its performance, making it suitable for modern brewing processes.

Mouth It's the texture of the beer in your mouth: its fizz, fullness, smoothness, dryness, and even the aftertaste.

Two beers with the same alcohol content can still have very different mouthfeels, depending on the mashing method, malt type, carbonation level, and style.

Musty It has a "musty," "stale" smell, which could come from moldy or contaminated bottle caps, or poor storage conditions.

This is often a sign of a defect, evident in both the smell and taste of the beer.

Myrcene It is a common essential oil in hops, often evoking fresh, green, resinous, or fruity notes.

Myrcene contributes significantly to the "explosive hop aroma" in many modern IPAs.

Natural carbonation This is a method of naturally producing carbonation by adding a small amount of sugar to a container/bottle, then sealing it to allow the yeast to ferment again.

When yeast "consumes" the newly formed sugar, it produces CO₂, and this CO₂ is absorbed into the beer, naturally creating carbonation (commonly seen in bottle conditioning).

Ninkasi She is the goddess of beer in ancient Sumerian mythology. This name is sometimes used to evoke the spirit of "ancient beer" and the long-standing brewing culture.

Nitrogen Nitrogen gas is sometimes used instead of CO₂ to create "nitro gas".

Nitro creates a thick, smooth foam with a distinctly creamy feel, quite different from the sharp, fresh effervescence of CO₂. Nitro stouts are a classic example.

Noble hops These are traditional European hop varieties, renowned for their delicate, balanced, and "classic" aromas.

Traditionally, noble hops are associated with 4 regions main: Hallertau (Bavaria, Germany), Saaz (Žatec, Czech Republic), Spalt (Germany), and Tettnang (Lake Constance region, Germany).

Oasthouse It is the facility (usually located right on the farm) where hops are processed. drying and packing after harvesting.

Proper drying and storage help preserve the hop essential oils, thus retaining their authentic aroma when used in brewing.

OG is the proportion of soup (wort) Before fermentation, it reflects the total amount of dissolved substances (mainly sugars) relative to water.

Water is conventionally defined as 1.000. The more sugar is used in the cooking process, the higher the OG (e.g., 1.050, 1.080...). OG is often used to estimate the alcohol content and predict whether a beer will be "thin or full-bodied".

Oxidation This is a chemical reaction that occurs when beer comes into contact with oxygen, causing the flavor to "age," become less fresh, and lose its sharpness.

Oxidation often occurs during improper packaging, bottling, or storage, and is particularly concerning for hop-heavy beers.

Oxidized This refers to the state where beer has been oxidized, often resulting in an "old" smell/taste and a less fresh taste.

Drinkers often describe their experience using suggestions such as: wet wipes, cardboard, sherry or overripe fruit.

Package It's a general term for all types of beverage packaging. For beer, the most common packaging is... can and bottle.

Beer sold by keg is often referred to as draught beer (Beer poured).

Planet This is the upper part of the palate, often mentioned when discussing how we perceive taste.

In the context of tasting, "palate" is also used more broadly to refer to the ability to perceive and distinguish tastes of the drinker.

Pediococcus It is a group of bacteria. In most cases, it is considered a "spoiler" because it causes undesirable changes in beer.

However, in some styles such as Lambic,Pediococcus may be accepted or intentionally used to create acidity. Some strains can also create diacetyl, This gives the beer a buttery aroma/flavor, which is sometimes acceptable in small doses but is often considered a mistake if overdone.

pH It is a scale for measuring the acidity/alkalinity of a solution, according to a logarithmic scale. 1–14. 7 is neutral, 1 strong acid, 14 strong alkali.

In brewing, pH affects mash performance, flavor clarity, and the overall feel of the beer.

Phenols Phenols are a group of compounds whose odors and tastes are readily discernible. In the right style, phenols are quite "lovely," for example, their smell. clove in German-style wheat beer, or notes smoke in smoke beer.

But if used in the wrong place or in too strong a dose, phenols can have adverse effects. medicine, antiseptic Or the "band-aid" type, often resulting from boiled water, contamination, detergents, or packaging materials.

Pitching This step involves adding the yeast to the broth after it has cooled to the appropriate temperature.

Pitching at the right time and under the right conditions helps the beer ferment cleanly, consistently, and with minimal defects.

First fermentation This is the first fermentation stage, where most of the fermentable sugars are converted into alcohol and CO₂.

This phase usually lasts about 2–20 days, depending on the style of beer and fermentation conditions.

Priming This involves adding a small amount of fermentable sugars to finished beer before bottling/kegging, allowing the yeast to ferment again and create natural carbonation.

This is the foundation of bottle conditioning and some traditional conditioning styles.

Prohibition This was the period when the United States prohibited the production, sale, and transport of alcoholic beverages. The prohibition began on [date]. 18/01/1920 and end on the day 05/12/1933.

This period is sometimes sarcastically referred to as “The Noble Experiment”", and has had a strong influence on drinking culture as well as brewing history in the United States.

Punch This is the indentation at the bottom of some bottles. This design usually makes the bottle more rigid and sometimes aids in pouring/sediment retention (depending on the type of beverage).

Quaff It means drinking in one long gulp, drinking to quench your thirst. This term is often used to describe beers that are easy to drink, fresh, and suitable for drinking multiple glasses.

Racking This is the process of transferring beer from one tank/cabinet to another, usually to separate it from sediment and prepare it for further packaging or aging.

Real ale This is a popular style of beer serving in the UK, strongly promoted by consumer organizations. CAMRA.

Real ale is usually defined as beer that has Second fermentation takes place directly in the serving tank/bottle. and poured Do not use compressed CO₂..The result is a light, smooth, and very "pub" feel.

Regional craft brewery (According to the Brewers Association) is an independent regional brewery that has an all-malt flagship beer or at least one of those. 50% The product falls under the category of: all-malt beer, or beer using adjuncts. Enhance the depth of flavor. It's not meant to dilute the flavor.

Return Policy It is Germany's "beer purity law" enacted in 1970. 1516, regulations stipulate that beer can only be made from water, barley, and hops.

Yeast was added to the list later, when its role in fermentation became better understood.

Residual alkalinity This index indicates the "buffering" capacity of the mash, that is, its ability to resist pH drops.

Simply put: water with high residual alkalinity is more difficult to lower the pH of the mash, and this affects the brewing efficiency and flavor.

Residential sugar This is the amount of sugar remaining that the yeast did not consume during the fermentation process.

Residual sugar determines whether a beer tastes sweet, full-bodied, or dry.

Resin These are natural resins produced by certain plants. In hops, bitter resins such as humulone and lupulone contribute to the characteristic bitterness of beer.

Saccharification It is the process of converting starch in malt into fermentable sugars, mainly maltose.

Saccharomyces These are common yeast strains used for fermenting alcoholic beverages. In brewing, the two important groups are: S. cerevisiae (ale) and S. pastorianus (lager).

Secondary fermentation This is the second fermentation stage, which is slower. The duration can range from a few weeks to several months, depending on the style of beer.

This term also refers to the process of "re-fermentation" in the bottle/cask, usually triggered by priming or adding new yeast.

Sediment It is the sediment that settles at the bottom of the fermentation tank, brewing vessel, or beer bottle (especially with bottle-conditioned beer).

Session beer It's a light, easy-to-drink beer, so people can easily consume more than one serving at a time.

Typically, they prefer a lighter body and lower-than-average alcohol content, prioritizing "quaffability".

Solvent-like It is an odor/taste similar to acetone or solvent, often appearing when fermentation occurs at excessively high temperatures.

Sorghum It is a type of grain, often chosen in gluten-free beer for people with gluten intolerance.

Sour It is a sour taste, with an acidic and tart sensation. This taste can come from naturally occurring wild bacteria/yeast, or it can be actively created by the brewer using lactobacillus and pediococcus.

Sparing This step involves rinsing the mash with hot water to recover more sugar and remaining extracts from the seed hulls.

Chi gravity It is the ratio of the density of a liquid to that of water, used to estimate the amount of dissolved sugar in a cooking liquid or beer.

SG is a ratio, so no unit.Both OG and FG are different forms of measuring SG at different times.

SRM SRM is a scale for measuring beer color. The higher the SRM, the darker the beer.

For example, pale lager might be around 2 SRM,Stout can reach 45 SRM or higher.

Steaming It is the process of soaking a solid in a liquid to extract its flavor.

Step infusion This is a type of mash that increases the temperature in stages by adding very hot water, stirring, and then maintaining it at the target temperature.

Sulfur It smells like rotten eggs or burnt matches, possibly a yeast byproduct or a sign that the beer has been lightstruck.

Tannins These are a group of compounds found in grains and hops. Tannins from malt husks and tannins from hops differ chemically, but both can produce an astringent taste.

If the tannins are too strong, it feels like drinking black tea that's been steeped for too long: bitter, dry, and leaves a "wrinkling" sensation in the mouth.

Cau rests These are the "temperature benchmarks" in the mash process, allowing the brewer to adjust the ratio of fermentable sugars, thereby affecting the dryness, body, and feel of the beer.

Top rinse It is a type of fermentation where the yeast tends to float to the top, often creating streams. ale.

Compared to lager (bottom-fermented), ale is usually more flavorful and more prone to fruity notes due to esters.

Trigeminal nerves These are the nerves that sense temperature and texture on the surface. When drinking beer, they help us perceive "feelings" rather than "tastes".

Examples include: hot/cold, smooth/tough, thin/heavy, dry/cloying, and a slight burning or stinging sensation in the mouth.

Trub It is the residue of the brewed liquid, formed from proteins, hop oils, and tannins that coagulate during the boiling and cooling stages.

Turbidity This refers to the condition where beer becomes cloudy due to suspended sediment, giving it a hazy, murky appearance.

Volatile compounds These are volatile compounds that evaporate at room temperature, meaning they easily "escape" into the air.

In beer, these are the compounds that make up its composition. scent.Because they are volatile, they are usually perceived most clearly through the nose before being tasted.

Volstead Act It was a law enacted to implement the 18th Amendment, officially ushering the United States into a new era. Prohibition.

This law prohibits the production, sale, and transport of alcoholic beverages, and forms the legal basis for the ban that has lasted since... 1920 to 1933.

Volumes of CO₂ This is a way to measure the amount of dissolved CO₂ in beer, directly reflecting its effects. gas level.

For example: light carbonated beer can be around 1.5–2.0 volumes, while strong sparkling drinks like wheat beer can reach up to 3.0 volumes or more.

Vorlauf This is the reflux step at the beginning of the lautering process.

The liquid is drawn from the bottom of the lauter tun and gently poured back onto the surface of the grain layer, helping the cooking liquid to become smooth. clear and free of residue before placing it in the pot for boiling.

Water It is one of the four basic ingredients of beer and can account for up to 90% volume.

The mineral composition and pH of water strongly influence the style of beer. For example, hard water (high pH) in Burton famous for its bitter beer, while soft water (low pH) is Plzeň This led to the creation of the classic Pilsner Urquell.

Wet hopping This is a technique for brewing beer using freshly harvested, undried hops.

Wet hopping imparts a fresh, green, and very "seasonal" flavor that is difficult to replicate with conventionally processed hops.

Whirlpool This technique creates a swirling current in the boiler to collect sediment (hot break and trub) towards the center.

This term also refers to a specific device designed to separate hot residue from boiled cooking liquid.

Wort It is a slightly bitter sugar solution obtained after mashing and boiling with hops.

Wort is essentially "unfermented beer," and it becomes finished beer after being transformed by yeast.

Yeast It is a microorganism that converts sugar from malt into... alcohol and CO₂.

Men were first observed under a microscope in 1970. 1680, and by the year 1867,Louis Pasteur demonstrated the essential role of yeast in fermentation.

Yeast cake It is the layer of live yeast that settles at the bottom of the tank after the fermentation process.

This layer is sometimes recovered and reused for the next batch of beer.

Yeast Pitching This is the moment when the yeast is added to the cooled wort, officially beginning the fermentation process.

Zymurgy It is the branch of chemistry that studies fermentation processes, particularly in brewing.

This is also the name of the bimonthly magazine of the American Homebrewers Association, dedicated to the homebrewer community.
