Where do you guys/gals get your strong beers from?
Supermarkets/online local offy?
I suspect a lot of them came from specialist beer shops or online orders. I am a big fan of strong (as in higher ABV) ales but they arent really that popular in the UK compared to a lot of other countries... Probably because of the negative connotations surrounding high alcohol content but is also maybe a historic thing due to taxation as historically England used to brew barley wines and impreial russian stouts.
If you want to strong beers from supermarkets beyond Special Brew & Kestrel etc. The picking are a bit slim but there are a few out there.
Adnams Broadside (6.3%) is a decent ale and available in multiple supermarkets. A bit of a 'marmite' beer as has quite a unique taste.
Tesco Finest Double IPA (9.2%) Is made by Brewdog and is a good imperial/double IPA (not great compared to american DIPA but still good)
Chimay blue (9%) is a classic Belgian dark ale available in Tesco. Great stuff!
Duvel (8.5%) is Belgian strong golden ale available in lots of supermarkets. Very differnt style to Chimay but a great beer.
Old Tom (8.5%) is an British 'old ale' and very much of a winter beer with lots of complex malt favour and light on the hops. A really great beer and one of my favourites. Should be able to buy in Sainsbury.
Manchester Star Ale (7.3%) Like Old Tom another English 'old ale' with dark fruity/chocolate flavour. Available in Sainsbury.
St Stefanus Blonde (7%) Like Duvel this is a Belgian golden ale. Can be bought in Tesco but is a little pricey.
Waitrose and Marks & Spencer will likely also have some additional options.
