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.

I researched grapes which would grow well in Iowa and will produce a Porto style wine and this one is one of the few available.

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

I want to add to what I have. This grape has done very well here in northern Ohio on my farm.

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.
what will i be buying are these seeds or are they actually started grape vines?
Julia K on Feb 16, 2017
BEST ANSWER: Thank you for your question. You will receive bare-root plants, which are about 1 year old and 12-18??? tall. Our grapes will typically take 2-3 years after planting to reach maturity and bear fruit.
Is crop thinning necessary?
Steve H on Sep 30, 2016
BEST ANSWER: It's not necessary, but you will get much larger fruit with a better-developed flavor.

Four benefits of thinning out fruit are listed in this article: http://www.starkbros.com/growing-guide/article/4-benefits-thinning-fruit-trees
is this a seedless grape?
George R on Mar 12, 2016
BEST ANSWER: Frontenac Grape is not seedless.

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.

Trained to an Arbor (recycled screen tent frame) Impressive all around
This is our 4th year, and the grapes have come on in abundance, near drought in Downeast Maine yet these grapes, after a somewhat brutal pruning early Spring- have surpassed all of our expectations for a great wine grape. Harvesting today- 9-14-16, juicy, tasty and left to hang long enough to even out the acid. Highly recommend for cold climate growers.

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.

Vigorous plants
In a single year they grew to fill their 2 wire trellis. I'm spur pruning and this year I'll have a decent harvest, where other grapes would need another year at least.

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.

Frontenac Grape
Really don't know how they will do yet. Planted them a year ago and I see this springs growth just coming on. They seem to be pretty vigorous in the location they were planted. Have to put up the wires yet. Thanks
