Piwi (Pilzwiderstandsfähige) is a German term to define vine varieties that have been described previously as hybrids, direct producers, interspecific, disease-resistant or disease-tolerant.

Piwi cultivars have originated from cross-breeding (without the aid of gene implants) between European cultivars (Vitis vinifera) and disease resistant American Vitis species; although some newer crossings are more complex and a few contain Vitis amurensis genes from Russia / Asia.
The cultivars that are still known as hybrids or direct producers were bred between 1880 and 1935 in France.

Piwi implies a certain resistance or tolerance towards the fungal diseases that are present locally or worldwide. Such diseases infect all pure Vitis vinifera cultivars (e.g. Pinot noir, Chardonnay, Riesling etc.) where an out-of-control infestation can lead to total crop loss. These vinifera varieties need to be sprayed with approved fungicides 6 to 10 times during the growing season; the fungicides inevitably enter our environment.
