I’d type it all in but you should just check out the site below for the breweries and beer museums. But I do suggest in Belgium to hit Ghent and go into a little place called “Dulle Griet”. 250 soorten dranken :D Great atmosphere and practically a monument to beer itself. The inside is covered with beer signs and memorabilia. They even serve a drink which requires one of your shoes as ransom, which they hoist to the ceiling in a basket, for the tall glass. :P But, if you get a little schlockered you may want to bring a partner to the bathroom cause the stairs, in my opinion are not made for the drunk, sooo steep and spiraled! :D
