On tap at Ambulance, sumptuous toasted oak-chipped mocha stout, ‘akin to a gourmet chocolate bar,’ allows mild bourbon vanilla sweetness to contrast bitter cocoa nibs adjunct, French-roast black coffee influence and ‘toned down’ dry hop char. Black cherry, raspberry puree and black grape provide dried fruited backdrop for heavy brown-black chocolate richness. Valiant hybrid is one of 2015’s best ales.
