White wine

No, drink what you like.

Try Verncaccia, a white wine from the San Gimignano area.

I have the opposite taste, I prefer reds, except for Prosecco.

Unless you are dining in multiple-Michelin star type restaurants, you can order what you like.

Eve, I can't tolerate reds either and have had no issue at all ordering whites with anything (we don't go to fancyschmancy places, though). Drink what pleases you. :O)

Very cool! Can't wait!

They make wonderful white wine in Italy, and much of it is never exported to the states, so if you enjoy drinking wine, this trip will be a good opportunity for you to try new varieties.

I'm a red drinker but the Orvieto Classico is an amazingly good white wine. It's a short train ride from Rome to Orvieto - kind of fun drinking it where it's made and buying it from the family! Salute!

I usually drink red, but also like a good white. When visiting Italy in the summer, it can be hot and a good cold glass of white just hits the spot no matter what food you order. Can't wait to be in Orvieto and drink some good Classico this summer!

My wife wouldn't drink white until we went to Europe and the Vernaccia that Gordon suggested was what changed her mind. It's best chilled on a warm day. Nobody cares what you order BUT you may find the red you don't think you like goes really well with certain dishes. This is so much more true in Europe where wine and food have evolved together in small geographic areas for many years. They say "If it grows together, it goes together" and it is very true. Traveling has changed the way I view many things and especially food and wine. Keep an open mind.

Venice is in the Veneto region, which is famous for whites more than anything else, and that includes Prosecco.
Rome is the Latium region, that has mostly (great) whites, for which the region is famous.
Tuscany is more famous for reds (Chianti, Brunello, Montalbano) but has also some decent whites, like the Vernaccia of San Gimignano.
The notion that Italians drink only reds is a false myth that exists in America since most Italian imports in America are reds (and Prosecco more recently). But as you can see that is not the case at all, and it varies a lot depending on the region. However you can order Prosecco in Florence too and nobody will raise a brow. Actually a friend of mine in the wine business in Florence told me that they sell much more Prosecco than Chianti. Young Italians tend to prefer bubbly and craft beer, rather than red wine.

Thank you so much, Roberto! You've put my mind at ease. And such great information!
