Let's raise our glasses to the innovative Wychwood Brewery, Witney, who have now come up with an imaginative scheme to help beer lovers keep fit while supping one of the two Brakspear beers that they brew.

The Brakspear Oxford Ale Trail, which will run until Christmas, will earn everyone over the age of 18 who completes it a pint of Brakspear Bitter and a Brakspear T-shirt.

It's all quite easy. You pick up a trail passport from any of the dozen pubs listed below, then call into every pub to get it stamped. The stamp will be issued when you purchase either a pint of Brakspear Bitter, which is considered an Oxfordshire classic and was described by award-winning beer writer Andrew Jefford as "perhaps the greatest beer in the world", or the brewery's recently introduced Brakspear Oxford Gold.

Brakspear's Oxford Gold is 4 per cent abv cask-conditioned organic ale made from Target and Goldings hops, which has a really remarkable citrussy flavour.

As Wychwood's managing director, Rupert Thompson, said: "The rolling out of Brakspear's Oxford Gold is an exciting development for us.

"In the past, the quality and consistency of organic cereals and organic hops was limited and, especially for hops, there were very few varieties from which to choose. This situation has gradually improved over the last two or three years, encouragingly, and we are delighted to offer organic ale with both consistency and style."

The Oxford pubs taking part in The Ale Trail are The White Horse, Broad Street, The Eagle & Child, St Giles, Goose on the Green, Gloucester Green, Hobgoblin, Cowley Road, St Aldates Tavern, St Aldates, Chequers, 131A High Street, The Crown, 59A Cornmarket Street, Turf Tavern, Bath Place, Chester Arms, Chester Street, Radcliffe Arms, Cranham Street, Far From the Madding Crowd, Friars Entry, Royal Oak, Woodstock Road.
