I am throwing an Italian wine tasting party for some of my VIP clients, I have 5 bottles picked out, need ...?

a 6th. We are focusing on Tuscany, from which we have a Brunello, Venento from which we have an Amarone and a Suave, and Piedmonte, from which we have a Barbaresco and an good Asti. Does anybody know of a good Tuscan white that isn't to dry, yet to sweet? or another white from any of these regions that is a high quality wine? We are also having an espresso bar with Italian baked goods, hor de ouvres and Godiva chocolates. This is going to be a great business party, hosted inside a fine local jewelry store.

Vernaccia di San Gimignano

This is the most well known Tuscan white wine, partly because of its origin in the area around the famous hill town of San Gimignano. It is made from the Vernaccia grape, and is a light, dry wine of very reliable quality. It is a good wine to drink with seafood, or with Tuscan rabbit stew and other white meat dishes. It also complements cold meats such as prosciutto and salami.

I wish I was coming to your party! It sounds fabulous.

My Italian friend loves mochas. They're made with this tiny little pot. They're pretty good! Otherwise, for another white wine, how about a Pinot Grigio?

wine from Cinqueterre or Colline del sole...my favorite is a local wine from Massa Carrara called Candia not very easy to find...but too good....good luck!!!!!

Sounds like you have most of the bases covered.
I'm not that keen on white Italian vino, but i'd be happy to drop by for a tasting!
