I really didn't like the comment, "It is a taste thing."
I remember when I took a wine class several years ago and the instructor passed out some really excellent wines that cost very little, and some really crappy wines that were really expensive.
While the majority of the wines that were higher priced were better tasting, it is not a requirement.
Also, think of it this way, if Liz (or anyone else for that matter) loves the cheap stuff, then she wins because she doesn't have to high prices to enjoy herself.
I envy those that love the cheap stuff!
