On tap at Shepherd & Knucklehead, lofty rye whiskey-barreled full body offers bourbon-sweetened brown chocolate spicing to ascending hazelnut coffee roast. Burnt caramel malting contrasts silken burgundy, port and sherry wining. Recessive French vanilla, espresso macchiato and frappuccino undertones deepen smoked mocha conviction, but rye influence deadens over time.
