History

Bitter emerged in 19th-century England as drinkers' name for the draught version of pale ale, more hoppy than the mild ale then dominant in pubs. Over the 20th century, declining gravities and war-time rationing settled the style into today's sessionable strengths. When keg beer threatened traditional cask ale, the Campaign for Real Ale (CAMRA), founded in 1971, championed bitter as the emblem of British pub culture. Fuller's of London introduced ESB in 1971, giving its name to the strongest category of bitters.

Appearance, aroma and taste

Bitters are gold to deep copper and clear, with a low to moderate off-white head. The aroma combines bready, biscuity or lightly caramel malt with earthy, floral or herbal English hops and modest fruity esters. Despite the name, bitterness is moderate rather than aggressive, balanced by malt and finishing fairly dry. Cask-conditioned bitter has low carbonation and a soft, smooth texture. Ordinary bitter is light-bodied; best bitter fuller; ESB richer and more caramel, with more hop and alcohol presence.

How it is brewed

Bitters use British pale ale malt, often Maris Otter, with 5 to 15% crystal malt for color and caramel notes, and sometimes sugar or maize. English hops such as East Kent Goldings, Fuggles, Challenger and Target are typical. Burton-style water with gypsum accentuates the hop bite. A fruity English ale yeast ferments at 18 to 21 °C. Traditionally the beer is racked unfiltered into casks, fined with isinglass, conditioned in the pub cellar and served by hand pump at 11 to 13 °C.

Food pairing

Bitter is designed for pub food. It pairs with fish and chips, bangers and mash, steak and ale pie, roast beef, Scotch eggs and the ploughman's lunch of bread, cheese and pickles. Mature cheddar, Red Leicester and Lancashire are classic cheese matches. ESB stands up to roast lamb, game pie and hearty stews. Serve at cellar temperature to appreciate its malt and hop balance.

Bitter & ESB: questions and answers

What does ESB mean?

ESB stands for Extra Special Bitter. Originally the name of a Fuller's beer introduced in 1971, it is now used for the strongest category of English bitter, typically 4.6 to 6.2% ABV, with richer malt and firmer hops.

Is bitter beer actually bitter?

Bitter is moderately bitter, around 25 to 50 IBU, which was notably hoppy compared with the sweet mild ales of the 19th century. Today it is less bitter than most American IPAs and well balanced by malt.

Why is bitter served warm?

Cask bitter is served at cellar temperature, around 11 to 13 °C, not warm. This temperature lets the malt and hop aromas come through. Cask ale also has low carbonation, so it tastes smoother than chilled, carbonated lager.
