Marquette (grape variety)
Marquette is a red wine variety . It was crossed in 1989 by Peter Hemstad and Jim Luby from the grape varieties MN 1094 x Ravat 262 (also called Ravat Noir ). Hemstad and Luby are employees of the University of Minnesota , where Elmer Swenson previously worked. The variety has been approved for commercial cultivation since 2006. The grape variety was named after the French Jesuit and explorer Jacques Marquette .
MN1094 is already a complex intersection of ( Vitis riparia clone 64 x Carmine ) x (x Mandan Landot 4511 ) and also the grape Ravat Noir originated in five steps from breeding Seibel 8365 x Pinot Noir .
With the grape varieties Frontenac , Frontenac Gris and La Crescent, Marquette is now one of 4 patented varieties that are used in the cold wine-growing climate of the US Northeast and Canada. Plantings are known in the American states of Montana ( viticulture in Montana ), South Dakota ( viticulture in South Dakota ), Vermont ( viticulture in Vermont ) and Minnesota ( viticulture in Minnesota ). In Canada , the variety is found near Quebec. Even in cold wine-growing climates, the variety develops high must weights of up to 25 degrees Brix , which corresponds to around 100 degrees Oechsle . This value increases only marginally in warm years. The alcohol-rich wines are acidic and should undergo malolactic fermentation .
University staff were looking for early maturing and hardy varieties suitable for the northern United States. Marquette is hardy to at least −30 degrees Fahrenheit (-35 degrees Celsius). Since the roots are less hardy, the variety should be protected by a sufficiently high layer of snow on the ground.
