A top-performing red wine grape developed and released by the University of Minnesota, Frontenac is prized for its exceptional vigour, productivity, and cold hardiness. This variety thrives in northern climates and is one of the most reliable choices for Prairie vineyards and backyard winemakers.
Frontenac vines are extremely vigorous and highly productive, producing generous clusters of berries ideal for full-bodied red wines, rosés, and ports. The vines show strong natural resistance to disease, with particularly good tolerance to powdery mildew—making them easier to maintain in variable Prairie weather.
At harvest, Frontenac grapes typically reach high sugar levels paired with high acidity, a hallmark of cold-climate wine grapes. These qualities contribute to excellent colour, balanced wines, and strong fermentation performance.
