It's very difficult to grow winemaking grapes in Wisconsin, especially northern Wisconsin. It's just too cold, and the cold winters can injure vines, while spring frosts damage the grape growth.
Here's a great paper from the University of Wisconsin-Extension: http://learningstore.uwex.edu/assets/pdfs/A1656.pdf
Here's a quote about grape selection "Choosing grape cultivars for WI is a compromise of hardiness, early maturing fruit, and the quality and flavor of the grape. Of the hundreds of grape cultivars available, many will grow in WI, but only a few are consistently productive in WI's rigorous climate."
"The well known Concord grape, for example, will grow and produce fruit in WI, but requires a 155-160 day growing season for the fruit to ripen. Concord will ripen to best quality only in southern WI, and only two or three years out of five."
So, essentially, you should look into beermaking rather than winemaking.
