On tap at Ambulance, velvety maple-creamed Imperial Stout (brewed in collaboration with Maine-bound Bunker Brewing) retains brown-sugared maple molasses sweetness, sugary vanilla-laced chocolate caking and rich cookie dough malting above dark-roast hop char as bitter burnt wood singe and mild alcohol burn creep forward. Tertiary cola nut, toasted marshmallow, cappuccino and cocoa tones deepen decadent dessert beer.
