Frontenac (grape)

Frontenac (grape)

Frontenac is a vinifera hybrid grapevine that is a result of research and cross-breeding by the University of Minnesota. It was grown from a crossing of the complex interspecific hybrid Landot 4511 and a very cold hardy selection of Vitis riparia. It was released in 1996.

Frontenac gris is a white wine version of Frontenac, introduced in 2003. It started as a single bud mutation of Frontenac, yielding gray (thus named gris) fruit and amber-colored juice. Frontenac blanc will be introduced in 2012 from white fruited mutations found in both Fronenac and Frontenac gris vines in Minnesota and Canada.
