St. Croix tends to be vegetatively vigorous, but not terribly productive of fruit, so care must be taken in pruning to leave a sufficient number of buds to balance the vegetative vigor. Typically, St. Croix vines will survive mid-winter cold down to -32 to -33 o C without injury. The roots are a bit less hardy and need snow cover in really cold winters. Grafting on a superhardy rootstock may slighlty enhance its hardiness and productivity. St. Croix was developed by Elmer Swenson in Osceola, Wisconsin from a cross of ES 283 x ES 193. Perfect flowers.

Comments from Northern Winework: " Many award-winning red wines in Minnesota have been produced from St. Croix. It is also the main red wine variety at many wineries in Quebec. Clusters of St. Croix are medium and slightly loose, with the berries resembling those of Beta in size and color. St. Croix ripens in midseason in the St. Paul area of Minnesota. The acidity is moderate, but the grape struggles to make 20o Brix in sugar. This is true even in hot summer climates, such as in Missouri. The juice is a pale rose and the wines can be quite dark in color. The lack of tannins in St. croix wines is fairly common and needs to be corrected by blending. The wines often suffer from a tobacco-like nose. However, fruitier wines have been made from St. Croix grapes fermented with semi-carbonic maceration techniques. The press run fraction can produce some very special wines.
