I don't drink at all not even a small amount, but if someone asks me to taste something, I will try it as a little bit on your lips would not start any allergies anyways. However if you don't feel comfortable around alcohol, then definitely don't drink it. I hate cheese so even if someone asks me to try some, I would say no, and when they ask why I would say "Because I hate cheese". Say that to people when they ask you to try some just say "I don't like alcohol, say the taste of alcohol makes you feel sick". They wont ask any more questions.
