PIWI Wines are wines from fungus-resistant grape varieties.
Today in science and research is increasing by "New innovative grape varieties" spoken in this context.
These grape varieties have a high resistance to fungal diseases and allow a significant reduction in using pesticides. These robust or innovative grape varieties are therefore an obvious alternative to conventional intensive crop protection.
Why do vines have to be resistant?
In winegrowing, considerable amounts of pesticides are used against mildew (fungicides) to prevent possible fungal infections and to secure the harvest. According to analyses by the statistical office of the EU (EuroStat), the use of pesticides per hectare and year in winegrowing is by far the highest compared to all other agricultural products produced in the EU.
However, PIWI vines have a high resistance to fungal diseases and allow a significant reduction in the use of pesticides, thus protecting the environment.
Enjoying quality wine is being revolutionised in a new way. Consumers get the opportunity to explore new undiscovered paths.
A win-win situation for winemakers and consumers!
How do fungus-resistant grape varieties develop?
The fungus-resistant vines are originally made Crossroads between Vitis vinifera and other species of the genus Vitis.
The excellent properties for high wine quality of the noble vines can be combined with the resistance from the American vines.
Specific cultivation and selection aim at developing new innovative grape varieties that make winegrowing more sustainable and meet the future challenges in the vineyard.
Genetic engineering methods are used in the breeding techniques of Vine resistant grape varieties locked out!
Where do the "new varieties" come from?
PIWI Wines are already widespread in German winegrowing regions such as Rheinhessen, Franconia and Palatinate. But they also are becoming increasingly popular in other winegrowing countries like Poland and Denmark.
Cultivating these new robust and innovative varieties is a long-term project through generations. Even today, vines are not cultivated in the laboratory, but in the vineyard without genetic engineering.
For many years, the Freiburg State Institute of Viticulture has been focusing on the cultivation of new fungus-resistant grape varieties. The State Institute of Viticulture is looking for interested companies who are willing to take part in the experiment and plant such vines in their vineyards.
PIWI International supports the Exchange of experience between winegrowers and breeders and stimulates the dialogue about the "new grape varieties".
Fungus-resistant grape varieties should complement traditional varieties such as Riesling and Pinot Noir.
