The family who produced wines under Château Tour Grise had been around a while, allegedly planting and tending vines since the 19th century. In 1998, they achieved biodynamic status, which they believed to be crucial in creating wines that express a true sense of their terroir. Since then, they had been renting off bits of vineyard to new, younger generation winemakers in an attempt to keep the blood flowing in Saumur, and up until recently they made wine from just 8ha, consisting of 6ha of Cabernet Franc, 1ha Chenin blanc, and 1 ha of Pineau d’Aunis.
