If you’re up in bonny jockland the Orkney brewery do some lovelly beers – dark island, northern lights, skull splitter (!!!). Bridge of Allan brewery do an organic beauty called Lomond Gold which is available by mail order or from local stores.
Outside my locality Badger brewery stuff is a personal favourite although you don’t seem to be able to get Blandford Fly round here any more (the one with added ginger to keep the bugs away). But Golden Glory and Tanglefoot are rather nice.
Black sheep beers are all good (especially the rig welter)- even better straight from the brewery & you can nip next door to Theakstons to try out the Old Peculiar.
