Originally from the Danube basin, Sylvaner is widely planted in well-exposed locations in Valais where it ripens later than Chasselas, producing wines with good body, bouquet and acidity. It is also used, although rarely, for late harvest wine.
Bernarda
An old vine, but you won’t find it for sale anymore. However it’s being experimented with by Jean Nicollier (I’m searching for more references). The Bernarda is a Prié blanc from the Val d’Aosta that may have come into Switzerland over the St. Bernhard pass, and hence the name.
Pinot blanc
Pinot blanc is a mutation of Pinot Gris. It may have found its way up the Rhône to Valais with any number of mercenaries returning to Switzerland, and today small quantities are cultivated in many Swiss wine regions. When grown in favorable conditions it produces a fruity wine with good acidity.
Nothing more excellent or valuable than wine was ever granted by the gods to man.
