American India Pale Ale
American India pale ales have intense hop bitterness, flavor and aroma with medium-high alcohol content. The style is further characterized by fruity, floral and citrus-like American-variety hop character. Note that “fruity, floral and citrus-like American-variety hop character” is the perceived end, but may be a result of the skillful use of hops of other national origins. The use of water with high mineral content results in a crisp, dry beer. This pale gold to deep copper-colored ale has a full, flowery hop aroma and may have a strong hop flavor (in addition to the hop bitterness). India pale ales possess medium maltiness and body. Fruity-ester flavors and aromas are moderate to very strong. Diacetyl can be absent or may be perceived at very low levels. Chill haze is allowable at cold temperatures.
