BJCP 21B
Hoppy, bitter, and moderately strong like an American IPA, but with some caramel, toffee, and/or dark fruit malt character. Retaining the dryish finish and lean body that makes IPAs so drinkable, a Red IPA is a little more flavorful and malty than an American IPA without being sweet or heavy.
Previously might have been a sub-genre of American Amber Ales or Double Red Ales, hoppier and stronger than the normal products, but still maintaining the essential drinkability by avoiding sweet flavors or a heavy body or finish.
