Mild ale is a type of ale. Modern milds are mostly dark-coloured, with an alcohol by volume (ABV) of 3% to 3.6%, although there are lighter-hued as well as stronger milds, reaching 6% abv and higher. Mild originated in Britain in the 17th century or earlier, and originally meant a young ale, as opposed to a "stale" aged or old ale.

The Campaign for Real Ale (CAMRA) is an independent voluntary consumer organisation headquartered in St Albans, England, which promotes real ale, cider and perry and traditional British pubs and clubs. With just under 150,000 members, it is the largest single-issue consumer group in the UK, and is a founding member of the European Beer Consumers Union (EBCU).
