On tap at Growler & Gill, variegated Christmas spices permeate rich and creamy (13% ABV) Imperial Stout. Wintry cinnamon-sugared nutmeg and ginger spicing decorates cacao-nibbed coffee adjuncts. Creamy vanilla icing covers fudgy Black Forest cake center. After a few sips, delightful chocolate mint cookie sweetness seeps into mild ancho chili peppering for Mexican chocolate-spiced entourage. Mesmerizingly complex.
