Fuller's is offering one person the opportunity to become a brewer for a day at its Griffin Brewery in Chiswick, London.
Running for the duration of Cask Ale Week from 27 September to 6 October, the nationwide campaign will determine the country's favourite cask ale.
To be in with a chance of winning, consumers simply need to take part in the ‘Cask Your Vote' competition in any Fuller's pub, allowing them to sample three different beers, served in 1/3 pint glasses held in a convenient Fuller's paddle where available. Drinkers will vote for their favourite, leave their details and the winner will be picked at random.
The prize will see the winner work alongside Fuller's head brewer to choose the best malts and hops, help with the brewing process (including the mash in, fermentation and cask racking) and, of course, undertaking some quality control by tasting a range of Fuller's beers.
John Keeling, head brewer of Fuller's said: "We're incredibly proud to be supporting Cask Ale Week again.
The beers available to taste include the new seasonal Traitors Gate (a ruby red ale, named after a gate at The Tower of London), London Pride, Seafarers, HSB, ESB, Red Fox, Chiswick, and Discovery.
