In the village of Meusnes, in the heart of Touraine, Jacky Preys and his son Pascal tend 80 hectares of vines — Pinot Noir, Gamay, Malbec, Sauvignon Blanc, and Chardonnay among them. But the family's true legacy is Fié Gris, an ancient, nearly extinct variety Jacky rediscovered in the 1980s: a patch of pink-skinned grapes on old vines that turned out to be pre-phylloxera survivors, later identified as an ancient mutation of Sauvignon Blanc. Since then, he has worked to revive Fié Gris and restore its place as a native Loire treasure.

Though the Preys family runs one of the larger estates in Touraine, it's their devotion to native varieties that sets them apart. They farm sustainably, hand-harvest their oldest vines, and favor minimal-intervention winemaking — using indigenous yeasts and gravity flow, and aging their Fié Gris on fine lees in stainless steel.
