Our signature sour wheat ale rested for nearly six months in Willie’s Bighorn Bourbon barrels, where time and oak left their mark. Finished with Sicilian lemon, tangerine, and Cara Cara orange, it emerges as Bozeman Underground’s interpretation of the whiskey sour cocktail. Layers of bourbon warmth and aged oak mingle with bright citrus sweetness and a gentle lemon tartness, creating a beer that honors a cocktail made timeless for a reason.
