Wow. That is a lot of grapes. I have two plants, Concord and Sunbelt.
Concord ripens its clusters a bit unevenly, and the skin is tough. This is why it is often used for juice.
Sunbelt ripens its clusters more evenly, and the skin is less tough; so, it is enjoyable freshly eaten.
Both have the same flavor (in my opinion) and both have excellent disease resistance here.
Concord 4/27/2026
I keep my vines at 15’ length only.
Even with heavy pruning, I still get about 2 gallons of juice from my Concord.
I eat fresh the Sunbelt which produces about the same amount.
Also, I use insect netting as soon as the fruit turns color, to prevent the birds from clearing the fruit.
If the weeds/grass are kept clear from around the trunk of the vine, they should do very well in ground.
You’re going to be very busy with 100 plants.
Best regards.

The thing I love about concord grapes is they typically don’t take much work here. I had 30 concords which I’m slowly losing to other parts of my orchard maturing. Everyone including my mom can never get enough grapes. I only have this time on this earth with family and friends we might as well enjoy from the vines together. I have several reasons I grow concord.
- High resistant to diseases like black Rot that destroy European grapes fruit
- I prefer the flavor. “Vitis labrusca that is used mainly as wine grapes and for manufacturing grape juice. The grape, a hybrid crossed with one-third Vitis vinifera, is named after the town in Massachusetts where it was developed” Concord grape - Wikipedia
- Heavy production up to 3 tons per acre

I wondered because I’ve had issues with a 2 and 3 wire trellis where the clusters, regardless of cultivar will manage to get entangled not only with other canes, but the wires.

In my experience what you are bringing up is an issue I have faced with pruning at times. I leave some of the best new growth on the 2 main vines. Think of 2 -8 inches of new growth being the part that sets fruit. Many people mention that their vines are 15+’ long. That is something I only do on arbors or very limited space. Most of my vines I keep with 6- 8’ range because Kansas is dryer. If the vines are short and properly pruned you will have less issues that you describe. New growth from last year is what sets heavy fruit and that makes it worth pointing out we do not want to over prune the vines either.
We owe our thanks not just to Double A but also to Ephraim Wales Bull (1806–1895), of Concord, Massachusetts, and the original Concord grape vine which he propagated and named in 1849. He grew thousands of vines to develop Concord. That is a picture of him and his original Concord vine.

The wineries I’ve been to do the same- shorter vines, more plants. Their mechanical harvesters are probably immune to the entanglements.

The Concord grape is a cultivar derived from the grape species Vitis labrusca (also known as fox grape). Vitis labrusca, commonly known as fox grape, is a woody, deciduous vine that climbs by tendrils to 40’ long. It is native to woodlands and forest margins in the USA. Vitis labrusca is used mainly as wine grapes and for manufacturing grape juice.The Concord grape, is a hybrid crossed with one-third Vitis vinifera . Vitis vinifera, the common grape vine, is a species of flowering plant, native to the Mediterranean region, Central Europe, and southwestern Asia, from Morocco and Portugal north to southern Germany and east to northern Iran. As of 2012, there were between 5,000 and 10,000 varieties of Vitis vinifera grapes though only a few are of commercial significance for wine and table grape production.

Concord makes an amusing wine. Certainly the “wrong” grape for a dry red, but interesting and bold flavored nevertheless. Fun to hand out tasting glasses and then note it’s made with the same stuff that kid’s fruit snacks and your PB&J for lunch are. A vibrant purple liquid.

Had to pick off grape clusters trying to form on the young plants.
i am jewish and from new york so i grew up with concord wine all around me, and even now its quite popular in my family.
I enjoy it. I prefer other foxy grapes, like catawba for wine. Im not a wine fan though so maybe why….

Concords from Double A look good. Can I recommend them for their good vines again without ruffling anyone’s feathers? I realize many great nurseries are on here that i also order from. I order a lot of things from many different nursery companies. I give my sincere review of what i order good or bad. For grapes why go anywhere else? They have been in the ground for 18 days and some have 6” - 18” of new growth. It is only May 12th. Well done Double A!!! I already placed a second order with them ! I need my old childhood favorites + experimental new types that though unproven may be superior. If you have made recommendations or have some please share. This is my second order Clarkinks Next Grape Order 2026

Do you have problems with brown rot? My concord vine planted in 2022 had its crop completely destroyed last year. Maybe because it’s shaded till about noon?
