A brand new variant of one of Founders Brewing Co.’s most famous stouts is being released this fall.

KBS Maple Mackinac Fudge is an 11 percent ABV imperial stout aged in bourbon barrels and brewed with Mackinac Fudge coffee and maple syrup. As the name suggests, the new beer is a variant of Founders’ Kentucky Breakfast Stout—otherwise known as KBS—an imperial stout aged in bourbon barrels that debuted in as a draft-only option in 2002 before being packaged in bottles for the first in 2003.

This would be only the second variant of KBS to be released, after Espresso KBS, a 12 percent ABV imperial stout that is brewed with “a massive amount” of both coffee and chocolate before being aged in bourbon barrels for an entire year in caves was released in November 2019.

According to Founders, KBS Maple Mackinac Fudge will be released in November packaged in four-packs of 12-ounce bottles.
