Frontenac (MN 1047) is a red wine variety from the University of Minnesota's grape breeding program. It bears large, loose clusters of  berries which produce a wine that has been confused with Pinot Noir. A cross of V. riparia 89 with the French hybrid Landot 4511, Frontenac combines many of the best characteristics of each parent.  Frontenac wine typically has distinct cherry and black cherry flavors. The herbaceousness of its wild riparia background is almost entirely absent. The color is usually a garnet red. Malolactic fermentation is essential to reduce the wine's high acidity. Tannin levels are usually relatively low. Oak is a good compliment to this wine-making grape.

LaCrescent  (MN1166) has a long and slightly loose cluster and turns a beautiful golden-brown color when fully ripe.  Ripe fruit of LaCrescent is made into a high-quality, semi-sweet wine with citrus and tropical fruit aromas.

Frontenac Gris is an unexpected, yet welcome, mutation of the University of Minnesota’s hybrid known as Frontenac. This coppery peach colored grape has notes of apricot and tropical fruit.. 

Prairie Star is a white wine grape developed by cold climate grape breeder Elmer Swenson. Prairie Star has long, slightly loose clusters.  The fruit matures to excellent sugar and acidity for white winemaking.  In some years, wines from Prairie Star develop a delicate floral nose that allow them to stand as single variety wines. In most years, however, Prairie Star is best used as a blending component to add body and finish to thinner white wines.
