Fredi Strasser is considered a pioneer in PIWI viticulture and from an early age was inspired by the idea of not having to spray his vines. Following this ideal, he devoted his life to researching and cultivating fungus-resistant grape varieties and recorded his experiences and findings in the book Fungus-Resistant Grape Varieties.
