I think I've overused the word, "nasty" to describe something I don't
like. I'm looking for a word to describe "bitter." I don't think
bitter comes from an overdoes of tannins, maybe it does, I don't
know.

As I prefer dry red wine, almost never sweet, so I'm used to wines not
being sweet.

I've not noticed that bitter relates to purple wines, tho.
I almost never like purple wines -- wonder if that's just me -- or if
it really means something.

Questions, questions, questions.
Thanks for any comments.
