Frontenac Gris

Red grapes for white wine.

Frontenac Gris is a sport of Frontenac. Culturally, it is identical to Frontenac, having high vigor and yields. Disease resistance is good, with moderate susceptibility to powdery mildew and black rot, and very low susceptibility to downy mildew. Small grey berries are born on medium sized, loose clusters. Berry splitting and botrytis have not been observed. Suitable for high quality table and dessert wines, possibly ice wine as well. Ripens mid-season with aromas that include peach, apricot, citrus, and pineapple.

The White Version of Frontenac


The variety’s history can be traced back to a single cane on a single Frontenac plant, which began bearing pink-skinned berries instead of black. Such pink-berried mutations are not uncommon in the grape world; other well-known examples include Pinot Gris and Gewurztraminer. The new cultivar was successfully propagated from cuttings, and commercially released as Frontenac Gris in 2003. It is now cultivated for wine-making in several US states, notably Minnesota and Vermont.
