The very productive vine with arching canes has some disease resistance to bunch rot and downy mildew, and has low to moderate susceptibility to black rot. Frontenac Gris can experience some foliar phylloxera and powdery mildew.

The fruits are borne in medium to large, loose clusters. These can vary from reddish-gray to coppery-peach, or gray with pale red. They ripen from mid to late season, usually in September, 2 to 3 days before Concord.
