On tap at Shepherd & Knucklehead, thin one-dimensional dark ale loses initial Hershey’s Kiss black chocolate delight and settles for arid hop-charred nuttiness. Despite adding Cafe Calabria coffee to barley-flaked oats roast, lactic cocoa-powdered acridity and sooty peat reminder outdo quick java swipe. Mucky mocha murk diverts black cherry snip. Way too watery, inefficient and uninvolving.
