1. Founders Brewing Company: The Journey From A Dream To A Craft Beer Legend
Year 1997, in Grand Rapids, Michigan, two guys Mike Stevens and Dave Engbers lit the fire of passion with the humble name Canal Street Brewing. But it wasn't until 2000, when they decided to change the name to Founders Brewing Co., that the craft beer world truly witnessed a flavor revolution. Not following the crowd, Founders chose the path bold, bold, where every drop of beer is an artistic statement.
And then, year 2007, they launched Kentucky Breakfast Stout (KBS) – a masterpiece aged in bourbon barrels, driving beer connoisseurs crazy. Just one sip, people realized: Founders are not making beer, they are writing a legend. By 2014, the factory expanded, with a capacity of 900,000 barrels/year, proving its irresistible appeal. And when Mahou San Miguel (Spain) acquired 90% shares in 2019, this brand officially expanded to the world, but still kept the free spirit, full of Michigan.

2. Underground Mountain Brown: Masterpiece In The Dark, Shining Like A Volcano
Year 2018, in the Founders' secret cellar, a "monster" named Underground Mountain Brown was officially born. It is no coincidence that it belongs to the Barrel-Aged Series - the same class as KBS and Backwoods Bastard, the legends that made the brand's name.
This is Symphony of Complexity: aged oak barrels, smoky caramel aroma, enchanting bitter chocolate flavor, and a warm finish from 11.9% alcohol. The founders do not hesitate to challenge tastes - they created Underground Mountain Brown for those who dare to enjoy beer as a work of art. Each bottle of beer is a captivating adventure, leaving the drinker overwhelmed and craving for another sip...
