Close to San Gimignano in the southern part of Tuscany you find the Agriturismo Le Tre Stelle (the three stars). These stars are three women who run an agriturismo with a little special twist. Every day they serve a joint dinner for all their guests at a long table in the patio. This dinner is homecooked and made from their own produce.
They also do nice wines. A white Vernaccia and good red ones. More on them later.
We learned about this agriturismo through a swedish TV-series on food and wine from under the Tuscan sun. This program gave them a bit of attention and some Scandinavian guests. If you are looking for that particular Tuscan experience, this may be the place to go.
