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.

Climate and Terroir:
Frontenac Gris is well-suited to the cool climate of Prince Edward County. The grape variety is hardy and can tolerate temperatures as low as -35C. The grape ripens in late September and early October, allowing it to retain acidity and freshness. The soil in our vineyard is mostly clay-loam, with good drainage, which helps the grape to grow healthy and strong.

Viticultural Considerations:
Frontenac Gris is a vigorous vine, requiring a strong trellis system and proper pruning to manage yields. The grape is resistant to common cold-climate diseases such as powdery mildew and black rot and is also tolerant to downy mildew. The grape variety produces medium to high yields, with a potential of up to 12 lbs of fruit per vine. It can be trained onto Vertical Shoot Positioning (VSP), High Wire (HW), or Geneva double curtain training systems.

Wine Profile:

The wine has moderate acidity, making it a well-balanced and versatile wine. We use this variety in our Inclusion Orange wine and Ophelia Piquette.
