Any suggestions?
Try the Slow day in Tuscany http://www.slow-days.com The day trip leaves from Florence in the morning and spends most of the day in the small villages and vineyards of Tuscany.
If your budget allows, I did a terrific wine tasting with a small group from Artviva, based in Florence. They have a website www.artviva.com.
I enjoyed an afternoon winery tour & lunch @ Verrazzano Winery. Check out the website http://www.verrazzano.com/en/
