A whole lot of wine is produced in Italy, so why not join in on a wine excursion while visiting the nation? There is a trip organised daily to the Frascati area just outside Rome. The vineyard visited is one of the oldest and largest in the area, and it is owned by the Palavacini family. Those joining in on the trip will get to taste 3 wines and get to hear about the wine production from a local guide with lots of knowledge.
If you want to drink Italian wine without leaving Rome, just go visit one of the many restaurants in Rome, and enjoy some great Italian food combined with some good wine instead.
