Cooperative union of four families, the Valli Unite is a limpid cultural and farming association born over thirty years ago in the location of Costa Vescovato near Alessandria. A 100-hectare property —managed with great attention to the reduction of the ecological impact — in which cold meats, cheeses, arable crops and fruits are produced and of which 20 hectares are dedicated to a vineyard, planted with Barbera, Timorasso, Croatina and other grapes. A rigorously biological agriculture, they even have a stable to directly obtain organic compost used to nourish the fields and availment of compound green manures coming from leguminous herbs. In the winery, no selected yeasts are utilized and the sulphur is exclusively the one naturally produced in the process of winemaking. An exhaustive line of wines, in which the aspiration is to obtain a liquid that is alive and in continuing evolution.
