The Wine Grapes of Switzerland
Lafnetscha
Here’s an obscure language lesson. The name Lafnetscha is derived from the local dialect. Because the grape is harvested early, it makes for a acerbic wine which should not be drunk too young. In the local dialect, the verb to drink is “gelafft”, so laff-nit-scha is drink-not-already (sort of). As to the grape, it is one of the oldest in from Haut-Valais. Almost identical to the Blachier. Please see Completer for more information.
Mondeuse
An old red grape variety well known in neighboring Savoie, Mondeuse is a rarity found in scattered plots in Chablais (Vaud).
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.
Age appears to be best in four things--old wood best to burn, old wine to drink, old friends to trust, and old authors to read.
