Well, Boddington's Bitter used to be the great beer when I was a kid (ie, your age). But then it went global and turned into ice-cream. Now, if you can get it, Theakston's:

is a great brew. Like most things from Yorkshire, it's mental. BE VERY CAREFUL with this gear. And all northern lads on here will back me up, this beer is lethal. Drink just two of them then try and stand up.
Have you got a link to Systembolagets beer selection there Sebastian? I'll have a look at it for ya.
Don't get anything brewed further south than Derbyshire, though mate. It's piss.
