Amigne was brought to Switzerland by the Romans. This grape can also produce a Sauternes-like late harvest wine. These wines are ready to drink in two to three years, but some can be aged.
Arvine
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. The unloved Arvine brune has faded from the scene. Grand Arvine gets criticized for displaying little character, whereas the Petit Arvine tends to have a fuller bouquet and lower acidity. In blind tasting, Petit Arvine generally kicks ass against its plumper brother. Arvine is also an excellent grape for late harvest wine, which can be cellared.
Altesse
More appreciated on its home turf between Lyon and Lake Geneva, it thrives in Valais
Nothing more excellent or valuable than wine was ever granted by the gods to man.
