Bitter is a type of pale ale that has a bitter taste and a pleasant aftertaste. This truly English drink dates back to the 17th century when brewers began using hops. This is what gave the ale bitterness.
The alcohol content of the drink varies from 3% to 7%. For example, the low-alcohol Boys Bitter has an alcoholic strength of 3%, and the Premium Bitter has 7% alcohol. The beer varies in color from gold to dark amber.
Bitters are made by top (or warm) fermentation. This underlines its English origins, where most beers are brewed at warm temperatures.
