A recently released red wine grape (Landot 4511 x V. riparia) from the University of Minnesota, 1996. The vine is extremely vigorous, productive, and cold hardy. Foliage and fruit are highly resistant to downy mildew, and the fruit are resistant to Botrytis bunch rot. High sugar levels along with high acidity are typical at harvest. The acidity usually requires some adjustment during the wine-making process. Wines have been characterized by some tasters as having deep color with elderberry, cherry, and perfumy notes. Other tasters have found it to be too vinous and candy-like. More information on Frontenac
