Hi Marie,
If you're able to go somewhere near Florence, I went to Castello di Verrazzano (http://www.verrazzano.com/) which is just outside of florence in the Chianti Region (approx. 35 min bus ride from Florence). They offer lunch & dinner tour options. We did the lunch and absolutely loved it. This was one of the highlights of our entire trip. I would highly recommend looking into it.
For the lunch tour (Chianti Tradition), you start out with an approx 1 hour tour of the grounds/wine making. Then for lunch we sat on the terrace overlooking all of tuscany which was beautiful. Each person got a huge plate of a mix of meats and cheeses (there was a vegetarian version available). Then we sampled 4 wines, and after they poured they left the remaining bottles for the table to finish (and there were only 6 of us at each table). We also sampled a dessert wine and balsamic vinaigrette. And there was also bread with olive oil drizzled over it.
The views were amazing and the people were so friendly!
