Vigorous, extremely winter-hardy to -30 deg. F (ca -35 C.), heavy producing and disease resistant V. Riperia 89 x Landot 4511 (Noir) french/american hybrid variety created by the U. Minnesota Research Institute for upper midwest USA conditions. Susceptible to Powdery Mildew disease, but near-immunity to Downy Mildew, in excessively humid conditions. Ripens in late mid-season with good sugar content. Important to let fruit hang until fully mature in order to reduce troublesome high acids to reasonable levels. Used to produce a high quality, full-bodied red wine with cherry/plum aromas and moderate-to-low tannins that usually needs malolactic fermentation to reduce its cool climate acidity. Reportedly contains little trace of the wild V. Riperia herbaceousness. Recommended for North-Central regions of USA.
