UK beer options Jan -June

Obviously most of the festivals mentioned won't be on the same scale as GBBF and will probably only feature cask ale and cider.

Happy toping

 

Bristol is Awesome! The Mrs lived there prior to moving up north when we got wed so I spent many a weekend down there and it has only improved in the intervening years. Small Bar, Grain Barge, The Orchard, The Bag Of Nails, Coronation Tap, Merchants Arms etc.
York: Rook and Gaskill. Three Legged Mare, The Last Drop, The York Tap, The Blue Bell, The Guy Fawkes Inn, SOoooo many good pubs you'll be spoilt for choice

 

Echo what Aye is saying above. I live in Bristol and it really is a great happening place to visit for quality ale. At the end of the month there is Bristol Beer Week with loads of great events including the first Bristol Craft Beer Festival :

Other highlight is the CAMRA beer festival in March :

Great mixture of pubs, micropubs, microbreweries etc. being added to with the likes of Wild Beer Co. being a recent addition. Arbor, Moor, Left Handed Giant, Good Chemistry, Dawkins, Wiper and True all great local breweries with others like Lost and Grounded just starting up.
Famous Royal Navy Volunteer, The Lime Kiln (my fave), The Beer Emporium, Brewdog, The Barley Mow, The Three Tuns, The Drapers Arms to add to the above bar list.
