Tea, usually Darjeeling, although Prince of Waies is good, as is a nice Oolong. Strong and sweet.
I greatly prefer black teas over green. Haven't really tried any white teas honestly.
I must admit that both Earl and Lady Grey taste horrid to me - it's what I assume drinking hot perfume or boiled potpourri tastes like.
My disappointment upon first having Tea, Earl Grey, Hot was palpable.
I have been told that my sense of taste must be overclocked, but I think they're just paying more attention than most peoples

.
Can't stand coffee.
