I my younger days I drank Becks. Now I gravitate towards Sam Adams. My real weakspot though is a good single malt scotch (Glenfiddich being my favorite)
Well if I make it back across the pond, I will have to try some of the UK/European brews again. I have noticed that imports taste different due to shipping or using a local brewery to distribute.
Don't have a specific favorite per se, so here's a quick list of some of my favored brews.
Rochefort 10
Chimay Grande Reserve
New Belgium 1554
Ommegang Three Philosophers
Murphy's Irish Stout
Belhaven St. Andrews Ale
St. Bernadus Grottenbruin
Traquair Jacobite Ale
Unibroue Quelque Chose
Lindemans Framboise
