Coffee - I love the smell, but hate the taste. They all taste really bitter to me, no matter how many sugars I put in or how much milk I use to try to mask it. I have asked people to recommend me a coffee and even ones that I was assured "don't taste at all bitter" all tasted bitter to me
It's an odd one, I like the smell so much that I want to like it but I just cannot get used to the taste.
I also don't particularly like tea.
I can do some straight spirits. But straight cheap vodka tastes like paint stripper. Smirnoff black or blue is nice straight, as are some flavoured vodkas.
tonic water - blurgh!
