Gouais

Nicknamed the Casanova variety, Gouais Blanc is a very old variety from the north-east of France which through natural crossings has given rise to more than 80 new varieties throughout Europe, including Chardonnay, Gamay, Riesling, Furmint, and many more. Banned for a long time in France, where this founder variety has almost disappeared, it has however been continuously grown in Haut Valais (Switzerland) since 1540, under the name of Gwäss. Highly productive and resistant to winter frosts, Gouais Blanc is now cultivated exclusively in Haut Valais, where it produces highly acidic wines with a marked aroma of pears.
