The term fungus resistant is hidden behind the abbreviation PiWi. These are newly bred grape varieties that are highly resistant to gray rot as well as the common fungal diseases powdery mildew and downy mildew. New breeds are constantly being created by crossing resistant varieties with tasty ones. The use of genetic engineering is prohibited.
PiWis are ideal for nearly natural planting. Very few biological pesticides are needed in the vineyard. The almost complete absence of pesticides not only protects the vines, but also protects the health of winemakers and the environment. In addition, since spraying is very labor-intensive, production costs decrease in the long run.
A nice side effect of these future-oriented varieties is the new flavor horizons that open up to us.
Must try these white varieties
Solaris is the ideal snack companion. It is plump, fresh and tastes of exotic fruits such as pineapple and melon.
Johanniter is a safe bet for Riesling lovers, as it has a fruity and mineral character like the mother currant. Due to its usually slightly sweet style, Solaris goes well with light vegetable dishes and fish with an Asian touch.
These red varieties are good food companions.
Cabernet Jura resembles its French counterpart, Cabernet sauvignon, not just in name. Intensely colored wines have a dark fruit aroma profile. There are also hints of muscat grapes that add complexity. It goes well with a creamy risotto, as Cabernet Jura has pronounced tannins.
Divico grape yields soft, deep red wines. With violet floral notes, blueberry aromas and peppery spice, Gamaret is alluring and captivating. This makes them the perfect accompaniment to meat dishes.
Leading country Switzerland
PiWis cultivation is clearly on the rise in German-speaking Europe and the Czech Republic. Switzerland played an important role in this development early on because well-known breeders such as Pierre Basler and Valentin Blattner live here. According to the Federal Department of Agriculture, almost 3 percent of vineyards (400 hectares) were planted with PiWi vines in 2021.
PiWis are grown throughout Switzerland and are particularly popular with Central Swiss winemakers. The most planted blue PiWi grape variety is Divico, with Johanniter leading the way in white.
