What's worth adding here is I generally have huge logical problem with the whole "acquired taste" thing, I mean if something tastes like crap (I'm referring to coffee, alcohol, marmite etc.) why would ANYONE want to acquire the taste? What's the point of it? When I don't like something I just simply try it once, maybe twice and then I'm like "no, thank you, it's gross".
I used to think I'm beginning to like coffee because I really liked coffee cakes or Kopikos (not sure if you have them in the US), but once you realise these things are 60-80% SUGAR (!) then it's not the coffee you like in it at all, you most likely just carve sugar.
