On tap at Ambulance Brew House, uniquely soft-toned farmhouse ale loads white peppercorn herbage, kaffir lime tartness and mild coriander spicing into subtle citrus zest. Lemon-rotted souring initially overrides floral grapefruit-orange tang and lacquered wood drift. Thereafter, wispy mandarin orange, curacao orange and orange blossom illusions add ephemeral niceties.
