I'm Italian. I would say that for a decent bottle of wine (0.75 liter) you will pay at least 8/euro in a market. Good white wines are muller thurgau, vermentino, GewΓΌrztraminer (from trentino).
In a restaurant you should pay 4 euro for a glass and at least 15 for the bottle.
Of course this are price according to my definition of decent.
