Favorites: Rochefort Trappistes 8 for special occasions, Dogfish Head 60min IPA on draft at their brewpub, Sierra Nevada Pale Ale for casual drinking. Geez, I love so many of them, it's hard to pick just one! (I've had about 750 different beers and keep ratings of all of them.) Overall, my favorite style is probably IPA.
Best: I still can't pick just one. Rochefort 8 for sure, with Stone Ruination IPA a close second. I base this on 'goodness', not how often I would drink them.
Worst: Most macros are not good but still drinkable. Natty Ice, though, is gross. I had a John Harvards Strawberry Blond that tasted like strawberry cough syrup and chalk. Just hideous.
Experiment: Yes, but not as much as I used to. Right now I can't really afford to try a lot of the beers I would like to, so I stick with the tried and true.
Homebrew: No, I have too many hobbies already.
I am not specifically an IPA fan, but Berkshire Brewings Lost Sailor IPA is AWESOME!
