I have had growing experience with Marquette for 7 years now and making wine with it for 5 years. It is good and hardy for your zone and can ripen fairly early, depending on day length and gdd's. It is one of the first to break bud in the spring and blooms relatively early. You need good air movement in the vineyard to keep the frost away and the foliage dry of dew. It can yield very well, just don't push it too fast too soon. With that said, my training system trial showed it's capability this year. With 6.66 x9 foot spacing, I had Top Wire Cordon Produce 10.5 pounds per vine average. Vertical Shoot Positioned produced 9.5 pounds per vine, Scott Henry did better with 11.9 pounds per vine. My newly developed Modified Geneva Double Curtain System produced 25.4 pounds per vine. These were average weight in one repetition. The other two reps were decimated by the wildlife this year. I lost probably 5 pounds average to splitting and botrytis as a result of Hurricane Irene on the Mod GDC suystem. The most amazing thing was these are 3 year old vines!!!!
As far as the wine.....
It makes a decent to exceptional red wine which can range from a bit light to a nice deeply pigmented ruby color with some tannins and a beautiful black cherry flavor and smell along with varying earthy characters and sometimes a bit of vanilla and cassis. One of the best wines I have ever made came from 6 year old Marquette and sold out in days.
Give it a shot.
