Frontenac Grape Vine
Description
A cold-hardy wine grape. Developed at the University of Minnesota, this blue-black grape can withstand cold temperatures as low as -30°F and still produce grapes for making a good quality wine with a pleasant cherry aroma. Frontenac has been a consistent heavy producer and vigorous grape variety with a good resistance to powdery mildew and near-immunity to downy mildew. Grapes are produced on medium to large clusters that are usually slightly loose resulting in minimal berry splitting and bunch rot. Ripens in late August to mid-September. Self-pollinating.

Questions & Answers
Frontenac Grape is not seedless.

Being bare root stock: not that big. Seemed to be about a years growth on propagated cutting. A perfect candidate for shipping, but you'll have to expect to wait at least a year for them to produce.
That'd be up to the maker. Reports I've read suggest that the grape when grown well with unshaded clusters is capable of producing very high sugar levels meaning high alcahol or residual sugar if fermentation is stopped It hasn't fruited yet for me so I can't say personally.
No Our Nursery is in Louisiana Missouri.
Ours did not produce much the first year, but the 2nd year after a good pruning in the spring our vine did really well.
My Frontenac is in it's second yearn on a 3 wire cordon, I have topped the height on the trellis at 7'. I dont see why you couldn't keep the height under 6' with pruning/training. Width is a much bigger concern with grapes for me
They are good to eat fresh. They are a little tart but sweet. They have seeds in them of course. I am growing them to make wine but don't quite have enough production yet. Last summer was only the second year. I have three vines. Expect to have enough this year. I made jelly with them and it was good. I added very little sugar and it was still sweet enough for us.
Ours are pretty much direct sun.
Doing pretty well 2 yrs in. Quite happy. No fruit yet but only 2 yrs old.
We live in Colo and the grapes are doing great! It’s been almost four years.
