fungus resistant grapes

 

In the Valais we are pioneers in natural wine-growing and in promoting types of grapes that are fungus resistant. These resistant grapes are called ‚Piwi’ (from German: pilzwiderstandsfähig) and we don’t have to spray them against fungal diseases. The Piwi cultivars are crossings between European cultivars (viniferas) and disease resistant American species; newer crossings are very complex and contain even species from Asia. However the varieties were made by traditional crossbreeding without the aid of gene transfers. The goal is to combine the resistance against the diseases with the quality of the European varieties.

 

Muscat blue which is an example of a resistant root stock is a good table grape and produces a rosé wine with a bouquet of mango, quince and orange aromas. Such root stocks obviate the use of fungicides which otherwise would require regular spraying. (English winegrowers have turned to the white Seyval blanc grapes for the same reason.)


Another top Piwi-wine is our red wine Tambourenblut (‚Blood of the drummer boy’) which is an assemblage of five different resistant root stocks. It has a fruity, spicy aroma with wild strawberries and cherry overtones and a good acid structure with strong tannins to balance.
