On tap at Taphouse 15, punctual grapefruit-peeled orange zesting and brisk lemon tartness lead thick, but not creamy, Citra-hopped Imperial IPA. Grungy cannabis pungency and herbal black tea musk settle below citrus-spiced pleasantry as slightly sour key lime pie, green mango, guava and passionfruit illusions contrast rummy Pina Colada-like coconut and pineapple sweetness over silken flaked oats. Superb!
