Castle Pubs, the Mitchells & Butlers-owned, 115-strong brand, is to launch Craft Keg Fest showcasing the best of British breweries.

The UK’s largest keg craft beer festival will serve over 50,000 beer enthusiasts between sixteen and thirty rotating craft beers and will run from 3April – 26 June.

The pubs will rotate a wide and diverse range of craft beers throughout the twelve-week festival, with beers including Siren Soundwave IPA, Brewdog Ace of Chinook, Four Pure Vienna Lager and Meantime Raspberry.

A host of exclusive beers will also be on offer during Craft Keg Fest, including Hogstar Pale Aleand a new beer created by the Castle pub managers in collaboration with Cloudwater Brewery in Manchester. The next beer from London’s award-winning Meantime Brewery, Alpha Delta will also be available exclusively at Castle pubs during the festival.

Craft beer fans will also receive a “Crafty Fox” reward card as part of the festival – buy six pints and get the seventh free.

Ben Lockwood, craft beer and cider procurement manager for Mitchells & Butlers, said: “There’s a huge appetite for craft beer at the moment. It’s the perfect time to do one of the largest ever craft beer festivals in the UK and with all 115 Castle pubs taking part, it’s a sure way to attract more beer enthusiasts to our pubs. Some of the lesser known breweries will be able to get their beers in front of a completely new audience and grow their fan base.”
