On tap at Doherty’s, dry milk stout brings Rustica coffee bean roast to nutty chocolate opulence. Beneath the surface, black chocolate, Godiva chocolate, frothy espresso and vanilla bean illusions pop up alongside Brazil nut, hazelnut and cola nut nuances. Soft mineral-watered smoothness provides crisply clean flow for milk-creamed coffee finish. In the bottle circa ’18, mild coffee-roasted espresso bean presence competes favorably with bittersweet black chocolate tones and hop-charred walnut-cola conflux, finishing with a silken carbolic briskness.
