The winegrowers' cooperative, based in Bex in the Swiss canton of Vaud
, was founded in 1880. Its 160 members cultivate 38.5 hectares of vineyards. Almost 50% of these are Chasselas, while the other half is largely planted with Gamay and Pinot Noir, as well as Sauvignon Blanc, Pinot Gris and Chardonnay. The premium wines include the "Sire de Duin" and "Bex Blanc" pressed from Chasselas, rosés from Gamay and Pinot Noir, the red wine cuvée "Sire de Duin rouge" from Pinot Noir and Gamay, as well as pure Pinot Noirs. We also produce sparkling wines from Pinot Noir and a straw wine matured in barriques from Pinot Gris and Sauvignon Blanc.
