I love good coffee, and I happen to be, as Mike said "impervious to bad coffee." I might not enjoy the flavor but I always enjoy the caffeine.
That said, the best coffee, IMO is cold brew coffee. It's the smoothest most coffee-flavored coffee I've ever had, without a trace of bitterness. Making it couldn't be any simpler, you just put coarse-ground coffee in water and let it sit in the fridge overnight. It does use more coffee per cup, as it were, but not significantly more and I think it's well worth it.
