🍇 For the final member of the Frontenac family....meet Frontenac Gris — The Pink-Skinned Member of the Family! 🍇
One of our favorite cold-hardy grapes, Frontenac Gris is a naturally occurring color mutation of Frontenac, introduced by the University of Minnesota in 2003.
This versatile grape is a great choice for northern vineyards, offering very cold hardiness, vigorous growth, and reliable productivity. Its small berries can range from dusty rose to copper, or gray-purple, with bright acidity that holds through harvest.
🍑 In the glass: Frontenac Gris brings beautiful aromas and flavors of apricot, peach, pineapple, citrus, and honey, making it incredibly versatile in the cellar. It can be crafted into:
🍷 Dry or off-dry white wine
🌸 Rosé or blush wine
🍯 Late-harvest & dessert wines
And for the growers and winemakers who like the numbers:
• 23–26 °Brix at harvest
• ~3.0 pH
• 10–14 g/L TA
• Around 0.3 lb per cluster
• Target yields of roughly 8-12 pounds per vine
