The other day I was talking with my girlfriend who is a non-English speaker. She told me she tried Listerine mouthwash but found it too "spicy." I went to correct her but realized that I didn't have a word for this flavor. Is she right: Can we describe the taste of alcohol-based mouth wash as "spicy"?
If not, what would be an appropriate word for this taste?
(I assume that taste is not purely subjective and that people's tastes of Listerine converge to some extent. I trust that those of you who have tried Listerine know the taste I'm referring to.)
