On tap at Ambulance, worthy Oregon-Virginia collaboration offers buttery rye-toasted honey nut sweetness, spiced prune-raisin richness and dry cereal graining to sharp charred hop thrust and subtle grapefruit dirge. Mild chocolate roast inundates caraway-seeded chestnut, almond and praline subsidy. In the 22-ounce bottle, heady auburn-browned roggenbier brings spicier prune-raisin affluence to Blackstrap molasses-sapped pumpernickel rye thrust.
