Frontenac gris

Frontenac grisFrontenac gris, the white wine version of Frontenac, started as a single bud mutation yielding gray (thus named gris) fruit and amber-colored juice. The vine exhibits the same optimum growth characteristics as Frontenac, and requires the same cultural practices.

In Minnesota, Frontenac and Frontenac gris ripen in late mid-season, and are good sugar producers with 24-25° Brix not uncommon.
