On tap at Shepherd & Knucklehead, bittersweet Belgian stout arouses green coffee beaning and cappuccino-milked creaming with sugar-spiced candi syrup. Modest bourbon barrel aging serenades loud mocha frontage. Hazelnut espresso, chalky cocoa and vanilla fortify dark chocolate interior, melting away some high end coffee tones. In deep recess, banana, cherry and plum nuances reside.
