In 1971, Veronique and Aime Guibert bought a Mas (farmhouse) and abandoned mill in the heart of a beautiful, wild valley through which flowed the Gassac river. After consulting Prof. Henri Enjalbert they planted vines in clearings in the middle of 4,000 hectares of forest - he was convinced they had the ''terroir'' to produce a Grand Cru of the future. The first vintage of their flagship red was produced in 1978 from roughly 80% Cabernet Sauvignon. By 1982, a respected French wine guide described Mas de Daumas Gassac as the Chateau Lafite of the Languedoc. The Rose Frizant was created in 1981, also from the younger Cabernet vines.
Today, the children of the Guibert family manage the estate, storing their harvests in an old cellar underneath the original mill. The five brothers have continued to fine tune the Mas de Daumas Gassac's Grand Vin and broaden the range with varietal wines and blends that offer great value for money under their Moulin de Gassac label.
