The Wine Grapes of Switzerland
Durize
Durize is a red wine grape, possibly indigenous, grown in the Valais district of Switzerland
Rèze
Rèze is an extremely rare white variety found only in Valais. Not often produced as a varietal, Rèze is blended with other Vieux Plants of Valais. Rèze was also used to make the historic “vin des glaciers”, an amber colored wine produced in Val d’Anniviers using the solera technique.
No longer done today, one method in the past was to store Rèze in larch wood barrels, which gave the wine resinous flavor similar to the Greek Retsina, and masking some grape flavor.
Planscher
Planscher belongs to a group of grapes that do well in the Alpine regions of Italy and in Valais, Switzerland. An ancient white wine grape vine once found in the Rhone valley, it was close to being extinct. Today small amounts of Planscher grow in Visperterminen, Canton Valais.
And how's this for a description of the perfect wine? "It's like the perfect wife--it looks nice and is nice, natural, wholesome, yet not assertive; gracious and dependable, but never monotonous.
