Vitis vinifera 'Zweigelt'
Widely grown in its home country of Austria since 1922, this hardy cultivar continues to increase sugars in cool fall weather, so it is an excellent short season selection. Vigorous vines are highly productive, bearing large clusters of very dark blue grapes that make a Pinot Noir-type wine.
Very promising in trials in our area, vines need 1600 GDD (Growing Degree Days). Yield potential is high, although thinning may be needed in areas with the lowest GDD ratings. Hardy to USDA zones 5-9.
