AA
apparent attenuation, giving an indication of levels of residual sugar. Calculated from original gravity minus final gravity

abbey-style
ale, brewed in the monastic tradition of the low countries but by secular brewers, often under license from a religious establishment. See also enkel, double, triple, quadruple, Trappist

ABV
alcohol by volume; the most common measure of the strength of an alcoholic beverage

ABW
alcohol by weight; can be calculated from original and final specific gravities of the brew

adjuncts
unfermentable additives that add to the flavour or texture of the finished brew

ale
beer brewed with a top-fermenting yeast (Saccharomyces cerevisiae)

alt bier
copper coloured, top-fermented beer made almost exclusively in Dusseldorf. Hoppy, slightly bitter beer - famous example is from Zum Uerige Brauhaus

ambachtelijk gebrouwen
Dutch for craft-brewed
Provided by: Des de Moor

aroma hops
hops chosen for their aromatic qualities. Generally added to the brew by dry-hopping, e.g. Goldings

barleywine
an exceptionally strong style of old English ale, typically dark, rich, fruity and malty

BCA
see bottle-conditioned ale

beer engine
mechanism used in traditional British pubs to pump beer from keg to glass, avoiding false CO2 carbonation
Provided by: Craig Druitt

Berliner Weisse
traditional low-gravity wheat beer style of Berlin, with a characteristic sourness imparted by a lactic fermentation, now only brewed by two breweries; usually drunk flavoured with raspberry (Himbeer) or woodruff (Waldmeister) syrup
Provided by: Des de Moor

bière de garde
lit. 'keeping beer'; a style of strong beer from northern France, traditionally a bottle-conditioned ale though today some more mainstream examples are bottom-fermented and pasteurised

bitter
most widespread style of pale ale in England and Wales, typically a dry, fruity, draught 'real ale' of moderate gravity (3-5% ABV) for session drinking. Many regional and individual variations: 'bitter' is a relative term (see also mild) since although bitters have a notably hoppy character, especially in southern England, they are generally much less aggressively hopped than some modern beers from other countries
Provided by: Des de Moor

bittering hops
hops chosen for their bitter flavour. Generally added to the wort by boiling, e.g. Fuggles

black and tan
a layered mixture of stout and lager or ale. The stout goes on top. Exists in many vareties, Guinness and Harp or Guinness and Bass being the best known
Provided by: Tommy Forslund

black velvet
a mixture of dry Irish stout and champagne
Provided by: Des de Moor

bock, bok
a strong, seasonal beer style from Germany and the Netherlands, probably originating from Einbeck in Germany [and originally top-fermenting], with the name deriving from dialect for the town name, though it also means 'billy goat'. Modern versions are typically strong malty lagers at around 6.5% ABV, often dark in colour, released in spring and autumn. Some contemporary Dutch interpretations are now once again top-fermented.

bolleke
lit. 'little ball', the characteristically bulbous stemmed glass used for De Koninck ale, from Antwerp, Belgium
Provided by: Des de Moor

bottle-conditioned ale (BCA)
an ale that is bottled as a live product with conditioning yeast. Technically classed as a real ale

doppelbock
a high-gravity bock

double (dubbel)
usually, a dark, sweetish abbey-style beer of around 6-7% ABV, following the model of the renowned Westmalle Dubbel trappist beer, but may also indicate the second-weakest beer in a range, or double fermentation. See also enkel, triple, quadruple

draught (US: draft)
beer drawn into a glass or pitcher from a keg or cask, normally by electric or hand pump. Often noticeably different in character and condition to the same beer from a bottle

the addition of hops near the end of the brewing process to impart aroma. The hops are par-boiled (so are not strictly 'dry')

dunkelweizen
dark German wheat beer, usually served cloudy with conditioning yeast

eisbock
a strong German lager in which ice forms in the final stages of secondary fermentation, thus concentrating the alcohol

enkel
Dutch for single: rare term indicating the weakest beer in a range of abbey or monastery beers. See also double, triple, quadruple

ester
chemical sometimes produced in the brewing process, producing a characteristic pear-drop aroma or flavour

faro
a sweetened young lambic, or a young lambic served with sugar that can be added 'to taste'

fermentation
the process by which yeast turns sugar (malt) into alcohol. One by-product (in the brewing process) is carbon dioxide, which gives many beers their fizz

fermentation haute

finings
added to the brew to aid clarity by causing the yeast particles to coagulate. Common types are made from fish scales or seaweed

framboise, frambozen
beer flavoured with raspberries: the best-known versions are lambics

lambic
a fruity and characteristically sour Belgian style of ale, which uses stale hops to avoid bitterness and ferments with wild yeast (e.g. Brettanomyces lambicus and Brettanomyces bruxellensis). The term is correctly used as an appellation of origin, with the producing area centred on the Zenne/Senne Valley on the outskirts of Brussels (the term is believed to derive from the name of a village in the producing area, Lembeek)

Les Amis de la Bière
French beer-promoting body. Partly responsible for launching seasonal styles in France (see also CAMRA, Craft Brewers Guild)

mild
sadly rare British style of usually draught ale, mild in comparison to the hoppier bitter though never very sweet, often brown or dark in colour ('dark mild') though pale examples ('light mild') are also found, usually moderate in alcohol (3-4% ABV) but some stronger examples (up to 6%) are brewed

quadruple (quadrupel)

Provided by: Des de Moor

specific gravity
density of a liquid expressed as a ratio to that of water

stout
originally 'stout porter', a stronger version of porter, but now indicates a number of distinct styles of dark beer, of which the best known is the dry, creamy Irish stout typified by Guinness, with a roastiness imparted by roasted barley. Other, rarer, styles are sweeter stouts from mainland Britain such as milk stout and oatmeal stouts, and the very strong Imperial Stouts, originating from England but so called because of their popularity at the Russian court in the 19th century
