To create it, the brewers worked directly with the folks at San Diego’s Mostra Coffee. First, they carefully selected four incredible Stouts, each aged in different bourbon barrels — six-year Fitzgerald, ten-year Eagle Rare, four-year Old Elk, and six-year Weller. They carefully combined the brews, then rested the blend on toasted and raw coconut, hazelnut, and a specially curated blend of Mostra coffee.
