Do you know what lives in a glass? The second collaborative whiskey from Foundry Distilling Company and Boulevard Brewing Company - whiskey made from Boulevard’s Belgian Style Quadruple Ale, The Sixth Glass. Aged thirty-two months in 30-gallon charred oak barrels, this unique whiskey brings the beer’s familiar Belgian flavors and aromas, like a pastry in a glass. At 100 proof, the pastry might be something more…devilish.
