I don't see the need to lie about it.

I don't drink because I don't like to drink. I don't like the taste, I don't like the feeling, and I don't like the aftermath.

I don't drink coffee either, because I don't like the taste. Someone wouldn't have to lie about why they don't drink coffee, so why is alcohol any different?

I'm told in both situations that "it's an acquired taste" -- that's nice, but I do not wish to acquire a taste for something I do not like.
