I didn't get too adventurous with Beer until being enlightened/corrupted by CP members. I was up to trying about 8 or 10 beers on the Beer Advocate top 100 list, and truthfully not many of them appealed to me enough to buy more.
One night robbieXor mentioned some Trappist Ales, which I promptly sampled. I really enjoy them more than any beer I have ever had. Granted, my experience is still limited, but the Westmalle Dubbel, Trappistes Rochefort 8, and Delirium Nocturnum are my current favorites. I've always loved beer, but never knew just how good it really could be.
I also like the Sam Adams Chocolate Bock, which I missed my chance buying due to surgery related driving restriction. But, hey, I like the 3 I have more, so no boo hoo's from me.
