-Brewmaster's Collective Exclusive- Our signature Velvet Merkin milk stout aged exclusively in Extra Anejo tequila barrels. We inherited barrels from a premium tequila producer in Mexico. We then chose to fill the barrels with the dark, roasty goodness of Velvet Merkin-the first time we had ever endeavored to marry a stout with tequila barrels.This beer was produced exclusively for the blending of our 2021 Anniversary Ale, marking the 25th anniversary of Firestone Walker.
