If all 190,000 members of CAMRA took a friend for a beer during the week and bought a pint for them both, that would be £1m in cash for pubs.
Cask Ale Week is currently in full flow and runs until September 29.
"Every pint of cask ale bought helps keep precious pubs open and at the heart of communities – and support from CAMRA members during Cask Ale Week is a fantastically constructive contribution to this worthwhile goal," said Cask Ale Week organiser, Frances Brace.
"Huge thanks to all those who have been in touch with breweries and pubs, creating some wonderful events for families and friends to enjoy. There's some really imaginative stuff going on – from beer yoga to brewery open days, collaborative brews, and beer-themed pub quizzes," said Frances.
The Campaign for Real Ale has thrown its support behind Cask Ale Week, which is spearheaded by Cask Marque, and its volunteers up and down the country are helping to organise events including:
Stockport Beer Week
A range of events and experiences are taking place across the city, from meet the brewers and educational presentations, to pub cellar visits, and an ale trail with prizes from Robinsons brewery. Comedian James Dowdeswell, who previously published his book The Pub Manifesto with CAMRA Books, will be kicking the event off with a stand-up gig.
Wigan Beer Week
The inaugural Wigan Beer Week, will celebrate 'everything beer, everything Wigan'. Beer is celebrated with a series of beer festivals, tap takeovers, brewery open days and meet the brewer events. More unusual events taking place in the week include 'Beer Yoga', a Beer and Pie Festival, and the 'Tipsy 10k' - a 10k run/jog/walk calling for a drink at no fewer than 8 pubs en-route.
Ipswich & East Suffolk CAMRA Ale Trail
The Ipswich & East Suffolk CAMRA Ale Trail rubs from 12 September to 6 October. Participants can pick up an Ale Trail passport to stamp and visit up to 32 local public houses plus Hopsters off-licence (or the Ipswich beer festival) to help promote drinking and socialising in some great venues.
