There's a pretty good beer tent at the Summer Sundae festival. There are 20 cask ales, many of the reliable kind, Hopback Summer Lightning, St. Austell Proper Job and Abbeydale Deception to name a few.
A couple of weeks back there was a tweet from Summer Sundae that said punters could take their own alcohol. I read it then read it again. I don't think I've been to a music festival where I could take my own booze since Monsters Of Rock in 1988.
So the best beer at Summer Sundae this year is Dark Star Hophead that I got from the Swan and Rushes and brought in a growler.
