The small road winds upwards through the rolling hills of Umbria, Italy. After passing the next bend, vineyards are all around.

This is the home of the wine cellar of the Cotarella family, in the small village of Monteccio. The winery, which enjoys a global reputation, is the centre of Riccardo Cotarella's network.
