Welcome to PIWI International

In order to enable the further dissemination of fungus resistant grape varieties, we encourage the collection and exchange of information between research institutes, grape breeders and refiners of grapes, wine gorwers and manufacturers of fungus-resitant varieties.

Since its founding in 1999, our association has grown steadily and has already more than 550 members from 21 different countries in Europe and North America. Of course new members are welcome at any time. Join PIWI International and support the future of the fungus-resistang grape varieties! (Membership Application)
