There's an interesting paradox surrounding ciders in Britain. A lot of what you'll find in mainstream bars or served with drinks at the restaurant near your hotel will be heavily processed, commercial brands.
These can be disappointingly sweet or with the bubbly draft actually a little irritating as the sulfide taste lingers - at least that's what I've found.
The paradox is more intense when you think about how many brands are actually Swedish imports, with notoriously sweet and lingering after tastes. All the while, the county of Somerset alone claims to grow more than 400 varieties of cider apples!
Where can you get the real stuff then?
Pubs have been under a lot of financial pressure, even before the chaos of pandemic. This has had an unfortunate effect of consolidating brewery brands or has turned plenty of local pubs into franchise outlets, all the while more profitable farms have seen a loss of diversity among crops.
You're going to have to go super local to find the best ciders! That means it will more likely come in a barrel than a bottle, certainly not a can.
Looking for truly local pubs in tiny villages is a wonderful way to pass your time on vacation, but you can also count on local events or the occasional market to host something more like a home-brew cider.
Lots of fun to be had in either case, just plan your transport well as proper cider is sold by the pint and the alcohol content in the really good stuff rivals wine! Cloudier can mean more flavorful or it can be stronger, sometimes too strong... but it's good fun to try for yourself and find which you like best.
