I would argue that taste is the ability to reason about one's own preferences.
A person who doesn't consider themself to have a taste in music and listens casually won't really be able to reason about why they like the music they do other than "I like the band" or "I like the song."
A person with taste in music is going to have listened to a larger variety, be able to speak passionately about it, and justify why they like and dislike particular music.
One is a boneheaded consumer, one is a fanatic.
Similarly with wine, you can't claim you've got taste when you've been drinking only red your whole life.
