While the harsh Wisconsin winters may not seem suitable for grape-growing, the climate and soil are surprisingly forgiving. In fact, grapes have been growing in the vineyards of Chateau St. Croix since 2004.
The vineyard is home to six varieties of hybrid cold hearty grapes: St. Croix, E.S. 6-16-30, Prairie Star, Sabrevois, Frontenac, Marquette and King of the North. The grapes have been delicately planted by hand on a 2 1/2-acre parcel of the 55-acre grounds of the Chateau St. Croix.
