Spring has its own language. It is the whisper of new buds through the thick soil, the moist breath on old trees, the sweet intoxication mixed with the late-season chill. And there, in the old oak barrels at the Jolly Pumpkin Brewery, Beer of Mars was born – not as a drink, but as the perfect translation of the transitional season, when heaven and earth come together to create miracles.
They say the most beautiful things are paradoxical. Beer is no exception. Sweet yet sour, classic yet unconventional, strong yet sophisticated – each sip of Bière De Mars is like a page of poetry written by artist Ron Jeffries, leaving anyone who has tasted it wondering: “Is there anything in this world that is both wild and seductive?”
How a beer originates from tradition Garden Beach French can also carry the soul Farmhouse Ale Michigan specialty? How to make the elegant sour taste of Brettanomyces blends with warm woody scents without conflicting? The answer lies in the passion without borders – which has turned Bière De Mars into a legend, not only on the shelves of prestigious awards but also in the hearts of beer connoisseurs around the world.
1. History of Jolly Pumpkin Artisan Ales – Journey of Fermented Dreams
Year 2004, between the regions Dexter, Michigan peacefully, a brewer named Ron Jeffries – former brewmaster of North Peak Brewing Company – ignited the fire of passion by founding Jolly Pumpkin Artisan Ales. More than just a brewery, it became an art studio of wild ales and sour beers aged in wooden barrels, with flavors as wild and free as the soul of its creator.
Their journey unfolds like a symphony emotional: Year 2009, Traverse City welcomes second facility, then 2012, Ann Arbor added a cozy restaurant & brewery space. The highlight was in 2015, when the collaboration with Sierra Nevada brought craft beers beyond the borders of Michigan, touching the hearts of beer lovers across the United States. In particular, Jolly Pumpkin is remembered as a pioneer of the style Farmhouse Ale, where every drop of beer is story of the land, yeast and time.

2. Bière De Mars – When a Name Is Also a Poem
Launched in 2005, Beer of Mars is the brainchild in the series of seasonal releases of Jolly Pumpkin, inspired by the classic French Bière de Garde but "enchanted" by Ron Jeffries with Brettanomyces - a wild yeast that creates a delicate sour taste, and the aging process in wooden barrels leaves an aftertaste warm, complex.
Initially, this beer was only for the connoisseur in Michigan, but the fragrance spread far and wide, Bière De Mars soon became a phenomenon across the United States and the international market. In particular, the Grand Reserve versions aged in wine or bourbon barrels make the connoisseur even more intoxicated, like drinking the whole spring that has been aged over the years.
Two words “Bière de Mars” (March beer) evokes the changing seasons of France, where traditional Bière de Garde lines are often sweet and rich. But with Jolly Pumpkin, they choose to "break the mold" - replacing the sweetness with a delicate sour note, adding a warm oak aroma, turning each glass into a journey of unexpected taste discovery.
The name is also a whisper about time: beer brewed in spring, when the earth and sky awaken, to give the drinker the essence of waiting. Perhaps, Ron Jeffries not only created a beer, but also wrote a poem with yeast, wood, and the heart of an artisan.

3. Bière De Mars – A Poetic Style Between Classic And Modern
Garden Beach – the phrase rings out like a French folk song, recalling the old farms of Nord-Pas-de-Calais, where beer is brewed specifically for the summer. But with Bière De Mars, Jolly Pumpkin has added poetry to this traditional material, turning it into a springtime symphony – gentle yet mysterious.
Drop by drop Beer of Mars The color is warm amber, like the sunset through old oak, sometimes tinged with a seductive reddish brown. The color is not too opaque, nor is it completely clear, but rather a bit hazy, like morning dew covering a field of barley.
- Malt Sweet with caramel, crispy toast, hints of wild honey from Vienna and Munich malts.
- Brettanomyces yeast Wild brings ripe fruit notes – purple plum, green apple, hints of wild mushrooms and damp wood.
- Barrel composting making the flavors blend into layers, like echoes of old wine or bourbon that once slept in the wood grain.
- Dry, slightly sour finish, leaving a warm aftertaste from 7% alcohol, like a gentle hug after a spring rain.
If Traditional Beer like a gentle country song, Jolly Pumpkin’s version is adventurous jazz – where the sourness from Brettanomyces and the oak give it an incredible depth. The French may be surprised, but it is this “calculated rebellion” that makes Bière De Mars an unrepeatable masterpiece.
