On tap at Ambulance, exclusive Barrier offering (2nd anniversary 2.0 version) brings dry citrus-spiced hop pleasantry to caramelized barley-rye malting. Mild hop astringency benefits lemony orange tartness and bright grapefruit juicing contrasting spun-sugar cotton candy sweetness. Sessionable sunshiny day fare fine as introductory IPA crossover for lighter thirsts.
