Good bottled Belgian beer is still pretty good imo, though of course not as good as it is in situ.
I guess Im developing the topic somewhat- but hey we're in the Jam Session, and what better than being able to talk about my first and second loves on one forum (guitars AND beer!)
I have been to Prague a couple of times, and on each occasion it has been absolutely clear to me just how poor most "lager" (ie cold fizzy beer) is in Britain, and probably in the States too. I can honestly say that every single beer I had in Prague was substantially better than any pint of lager I have ever had in the UK. Most lager sold in Britain, in pubs, is brewed for the masses in one or two huge breweries. Its brewed, imo, to taste of very little so as to appeal to as many as possible. Bottled Czech lager is much better, but still nowhere near as good as the same products on draft in Prague. Im afraid that the US Budweiser is an absolutely travesty of the name as far as Im concerned!
As for the Belgian stuff, I have become very partial to it in recent years. There is a wonderful place called Beers of the World, up in Norfolk (where I no longer live...) which is literally a small supermarket selling nothing but beer of just about every type and nationaility you could imagine. They have a website and delivery service for anyone interested...
