I just got ahold of some Koningshoeven (pronounced cone ex hoe ven) quadruple from Belgium, brewed by Le Trappe. On tap it was easly in the top 3 beers I've ever had, its like a a little mellower than a tripple, has a deep amber color, and has a little bit of a green apple hint to it, just an all around great beer. and ita 10% abv, so enough to put a smile on your face after just one.
I just bought a 4 pack ($13.99) so i'll be sure to get a picture when i pour a glass.
