What distinguishes Italian wines from French, Spanish (or American)?!
One of the staples of Italian wines is the Sangiovese grape (this is what all Chiante wines are made out of). Your wine seller can probably recommend a good Sangiovese.
Answers: I agree with andy F they taste better. And I think so because, they are less bold and tannic. French, Australian, and California wines seem to think that if they can amplify the wine-ness paint peeling aespects to the maximum possible amount, it's a good thing. Italian wines are softer, the smell doesn't go up your nose, and are made to better match a variety of different foods no matter what they are (even ice cream).

Well, Italian wines are from Italy, Spanish from Spain, etc.
I think that is not what you want to know, tho . . . the truth is that many countries have fine wines, from the same type of grapes.
Some to look for that are good, and cheap . . . Chilean, Hungarian. Trader Joe's has a nice selection of wines, at good prices, several under $5-6.
The old rules were red wine with meat, white with fish/chicken. The important thing is to drink the wine that you like. No matter the color.
Go forth and get tiddly - but don't drive! :o)
