The most important facts in brief

  • The Valais benefits from an open east-west valley with northern and southern exposures and a constant foehn wind that strengthens the concentration of grapes.
  • With only 500 mm of rainfall annually and large temperature differences, hot days and cool nights promote the development of the grapes’ aroma.
  • The temperate climate allows for high quality white, rosĂ©, red and sparkling wines in the Rhone Valley.
  • Vitiswiss regularly recognizes Valais viticulture for sustainable cultivation and the protection of biodiversity.

Climatic advantages of viticulture in Valais

The Rhone Valley is a so-called “clear” valley because it is open from east to west, with unique southern (altitude) and northern exposures. The permanently prevailing, light foehn wind blows over these vineyards in Valais and promotes the concentration of the grape juices. Down in the valley flows the Rhone; without it, our Valais homeland would not only be a helpless steppe landscape – without this water, growing vines here would simply not be possible. At the same time, we are blessed with minimal rainfall, with only 500ml of precipitation per square meter per year. The considerable temperature fluctuations with cool nights and warmer than average days are also real turbo engines for the aromatic structure of our grapes. And last but not least, the Rhone Valley is located in an ideally temperate climate belt for the successful cultivation and development of outstanding white, rosĂ©, red and sparkling wines.

However, this is only possible if we show due respect for nature. This is why we have continuously received the highest award for our activities from Vitiswiss (Swiss Association for Sustainable Development in Viticulture) for many years. Among other things, Vitiswiss promotes the production of healthy grapes, the preservation of landscapes and biodiversity as well as the conservation and promotion of natural resources.
