Want to fill your own bottles with fresh wine? There are three places that I found for doing just that. Bring your empty liter bottles (you can buy them at Ikea or Visotto) and enjoy some fresh vino!
And if my memory serves me correctly I don't think any of them were more than 2 euro. Boom!
The first is right across from the base in town, there is a large sign telling you there is vino. It's only open really specific hours (I think on Saturdays) but he will fill up bottles for you if you show up.
The second place is Le Favole (On SP 15). They have several different types you can get sfusi and it's all pretty cheap.
The last place is Il Nappo (Via Montereale near the garden store). Their wine wasn't quite as good as the other two but if you are wanting to do a comparison this would make a solid addition to your collection.
There you have it. Go buy some liter bottles and save on your wine purchases :)
