Frontenac Gris - A Disease-Resistant and Flavorful White Grape Variety
Frontenac Gris is a hybrid white grape variety known for its high disease resistance and strong fruity flavours. It is a natural mutation of the grape variety Frontenac. A newer variety that was released by the University of Minnesota in 2003, Frontenac is a cross between the grape varieties Landot Noir and a hardy vitis riparia grape. The grape has quickly become a popular choice among winemakers in the cold-climate regions of the United States and Canada, particularly in Prince Edward County.
