'Frontenac
gris' is a variety of grape (Vitis hybrid) with gray (or gris, in French)
colored fruit suitable for white wine production, and is well adapted to
the Upper Midwest climate of the United States. 'Frontenac gris' has an
unusual combination of high wine quality, excellent cold hardiness and
disease resistance, and very good productivity. 'Frontenac gris' was
originally identified as a sport of 'Frontenac' (unpatented), a variety of
grape of hybrid origin with bluish black colored fruit with red juice
suitable for red wine production that was introduced in 1996 by the grape breeding
program at the University of Minnesota Horticultural Research Center (HRC)
in Carver County, Minn.
'Frontenac
gris' has proven to be sufficiently cold hardy for consistent production in
east central Minnesota where temperatures frequently reach -35° C. during
the winter season. Field tests have shown 'Frontenac gris' to be at least
as cold hardy as the 'Marachal Foch' variety (unpatented), and
substantially cold hardier than the 'Seyval' variety and most other
presently available grape cultivars used for wine production.
