On tap at Copper Mine, glorious bourbon-aged version of standard barleywine (14% alcohol volume) perfect as slow sipping nightcap. Creamy Belgian chocolate-spiced entry enjoins brown-sugared vanilla, butterscotch, toffee and coconut sweetness as well as rum-soaked cherry, fig, prune and banana niche. Oaken remnant seeps into mocha influence. A terrific step up from original ‘back burner.’
