A promiscuous grape. Not good for much, but with a long, long line of descendents, including the noble Chardonnay and Pinot Noir. Possibly from Croatia, it’s called Heunisch Weiss in Central Europe.

The name Gouais is comes from ‘gou’, which is a scornful word from old French referring to its standing as the grape of the peasants. Very prevalent in the Ile-de-France and in the Champagne during the Middle Ages and perhaps brought into Valais by the descendants of the Ligurians.

Acidic and with little residual sugar, it’s primarily used to blend with low acidic wine to give it a bit of liveliness. Ampelographic studies in the old vineyards of Oberwallis have found a red Gwäss with the same characteristics as the white Gwäss. Almost abandoned, it survives in Haut-Valais hiding under the alias of Gwäss, thanks to Mr. Josef-Marie Chanton, http://www.chanton.ch/home.html
