Well, first off, what have you been drinking? What brands didn't you like? What flavors of them didn't you like?
Beer choice is similar to cigar choice, in the fact that everyone is gonna like different things.
For me, I like heavier, darker, malty, high-abv beers, like Stone Brewery's Double Bastard, Dogfish Head's Midas Touch, Brooklyn Lager, etc... Other people like IPA's, which are very hoppy, which I cannot stand. To me most IPA's taste like a skunked Heinekin. The only IPA I will drink is Dogfish Head's 120 minute IPA, and that is only because it is anywhere from 18%-20%abv.
