PIWI winemakers survey new PIWI varieties during the LWG event
New PIWI varieties from the LWG experimental cultivation:
Day of grape varieties organized by the LWG on Würzburg Pfaffeberg. New promising domestic and foreign fungus-resistant PIWI types of vine requiring less pesticide. Visited by more than 40 winemakers.
Due to many precipitations, 2016 keeps many winemakers under the pressure to fight against the onslaught of fungus. Mildew caused the winemakers huge trouble already by the middle of June, during the flowering season. Normally LWG based PIWI grape varieties are treated with the eco plant protection only three times. Fungus-resistant grape varieties “Regent” and “Johanniter” are popular among winemakers since quite a long time. Recently vine cultivation experts could achieve significant improvement both of the taste as well as the fungus-resistance. LWG applies the “minimal pruning system” while experimental cultivation since many years. This new method allows reducing the amount of work and plant protection products up to 70%, bringing an energy economy and providing conserving resources. Visitors had an opportunity to survey the new white varieties like “Donauriesling”, “Calardis blanc”, “Muscaris” “Souvignier gris” and “Cabernet blanc” as well as the red ones “Pinot Nova” and “Pinotin”, to taste and to compare the trial wines. PIWI winemakers shared their personal cultivating experience and offered to taste their wines.
