I either like a wine or I don't like it. I can't rate a wine like I can rate a film with a rating of 1 through 10. Wines? 1 = hate it. 2 = meh about it. 3 = wine is good.
4 = Do you mind if I drink the whole bottle?
Now, if I ever find the right wine that I like enough to drink the entire bottle I could use this wine glass.
