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.

Wanted a grape cold hardy, disease resistant and one to make a good wine.
Robert B on Apr 17, 2016
I want to add to what I have. This grape has done very well here in northern Ohio on my farm.

Trying something new. Very cold hardy and we sometimes get cold winters in Kentucky.

How big is each grape plant when you buy it?
Laura B on Mar 3, 2016
BEST ANSWER: 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.
Will these grapes make a wine that is dry or a sweeter wine?
Cathy on Apr 11, 2016
BEST ANSWER: 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.
is this a seedless grape?
George R on Mar 12, 2016
BEST ANSWER: Frontenac Grape is not seedless.

Frontenac grapes - great for cold northern climates!
We love our Frontenac grapes here in Chicago! They're extremely cold hardy, which is unusual for a vinifera-type variety. We couldn't be more happy with them. We'll order more in the near future.

The only thing we don't like is that the deer in our area preferentially eat our Frontenac grapes' leaves ( and they don't eat our concord grapes or Delaware grapes leaves). So, we've had to enclose them in 6 foot high tomato cages.

so far so good
The grape vines are very healthy looking and I have a lot of little grapes so far which if grow to full size should make more grapes then i can consume or use.

Overall decent plants
I bought four of these plants in March 2015. After a harsh winter (in the mountains of West Virginia), only three survived. Of the survivors, one plant is growing like wild-fire and even produced a couple bunches of grapes (I removed these to encourage plant growth this year). I believe the cold stunted the other two, but they have started putting on new growth as the first full growing season continues.

Frontenac Grape in Pueblo West, Colorado
High desert, (4400ft above sea level, hot dry summers, cold mostly dry winters usually) with poor clay soils or rocky shale soils. Despite this the Frontenac Grape loves it here, my plants are 3 years in the ground and are covered with grape clusters, hail damage got 40% of the grapes, maybe 3 weeks away from harvest, we will see how the wine quality is. Some other I tried do not like it here.

Lovely Grape
Planted these at the existing grape arbor. Doing great, and over wintered successfully. Looking forward to a tiny harvest this fall. Hopefully larger ones in future years.

Birds Love Them
The birds love these Frontenac grapes and I have been having trouble because they almost always beat me to them. The St.Pepin and LaCrosse grapes seem to fare better; I am able to harvest them before the birds and the wine is so good. I wonder if it is the color!

Cold Climate Grape
Seems like a slow grower in Southwest PA but definitely holds up to below zero winter temps.

Frontenac Grape
We are in May in Alaska and there is no sign of life in my Frontenac Grape vines. I don't think that they are right for Alaska.
