A very old small berry Valais grape, difficult to cultivate. It is an aromatic specialty limited almost exclusively to Valais. Some clone or mutation of the Muscat is grown on almost every continent.
Another delivery from Rome, there are actually three Arvine grape varieties, only two used for wine production: Grand Arvine, with the larger berries, and Petit Arvine, with the, you guessed it, smaller berries.
Grand Arvine gets criticized for displaying little character, whereas the Petit Arvine tends to have a fuller bouquet and lower acidity] In a blind tasting, Petit Arvine generally kicks ass against its plumper brother. The unloved Arvine Brune has faded from the scene.
Arvine is also an excellent grape for late harvest wine, which can be cellared.
