On tap at Doherty’s, interesting novelty combines light aji panca chili peppering with sweet potato and purple maize adjuncts, but curiosities get stifled by ashen black chocolate-malted cocoa powdering and sour coffee murk. Dry cola, walnut and Brazil nut illusions drift by. In canned version, dry cocoa-dried black chocolate malting gains strength against less obvious chili-peppered potato and maize influence.
