Bitter is an English specialty, and very much an English term, generally denoting the standard ale—the “session” beer—in an English brewer’s range. They are characterized by a fruitiness, light-to-medium body and an accent on hop aromas more than hop bitters. Colors range from golden to copper. Despite the name, they are not particularly bitter. Indeed, British-brewed bitters will often be less bitter than U.S. craft-brewed amber ales. A fuller-bodied bitter is labeled as “Extra Special Bitter” (ESB). These weightier versions of bitter often stand up better to the rigors of travel overseas than the lower gravity standard versions. An important element of faithful bitters is the use of English yeast cultures in fermentation. These impart a fruity, mildly estery character that should be noted in examples of the style. Bitters are now widely emulated in North America, sometimes with domestically grown hops, imparting a rather more assertive character than seen in traditional English bitters.
