Short Season Grapes

I’m happy with my grape harvest this year, and surprised they did so well considering we didn’t have more than 2 or 3 days without rain until Sept. But it was very warm. We’ve had many hard frosts starting the first of Sept., before berries were ripe. But this year we covered with a large tarp and that worked. So a few days ago I harvested my Marquette - 6#, Prairie Star - 1#, and King of North - 7# (one vine each, 4 yrs old). Marq. wasn’t quite as strongly flavored as last year, likely due to the rain, but pleasant. PS is a petite vine but the fruit ripens earliest and is nicely sweet. I hope it ups its quantity in the future, though it does tend to get overrun by vigorous Marq. KoN I was going to remove, it’s way too vigorous for the small space it has, but it ripened so well this year and it does have that very strong “welch’s grape juice” aroma, color, flavor (in a not so sweet way). But it did have a bit of black rot, though not much (picked off leaves and berries affected early) considering this blighty year. Many leaves of all had something or other. But very good fruit overall. Juice now in jars in the pantry waiting for apple cider to mix with (my favorite).

Bluebell has beautiful large fruit, as usual, but not quite ripe. Looks like it’ll make it though, maybe next week. No bird damage so I’m comfortable letting it hang awhile more. The birds apparently prefer the large Autumn Olive crop nearby, thank goodness.

Brianna and Sommerset planted this spring grew well. Brianna very vigorous and may be more leaf disease. We’ll see how that goes. But Sommerset looks great. Moderately vigorous (suits my space better) and healthy. Made it to the top wire! Can’t wait for a harvest. Meantime I’ll just drool over Jesse and others photos.

Thought I’d give an update on my grapes. Winter of '17-'18 was a record vole year and for the first time ever I had vole damaged vines so it was hrd to determine what was winter kill and what was caused by vole damage. There was quite a bit of both.

This past winter I figured would be a good one because we had more snow than usual (3 ft instead of 2), but the grapes weren’t as impressed as I was. It was also a very long cold winter, started early. Winterkill was significant, scattered, both low and high.

Bluebell came through the best with just minor winterkill. A June 4 freeze (24 deg) killed some early opening leaves but I had enough good buds to easily prune to 40.

Prairie Star was next with a lot of winterkill (about 1/4 - 1/3) with scattered live buds, some damage from the June 4 freeze but enough good buds left and secondaries coming along to prune to 40 buds, and a good chance for a decent harvest. Thankfully it’s tops for early maturing.

Marquette unfortunately may have to be replaced. It had significant vole damage previous winter but had grown vigorously last season (maybe too much for vole damaged roots?). But most of the vine winterkilled this year. It’s possible it’s just not as hardy as I’d thought but I’m not giving up on the variety. I’m guessing damage. It’s growing new shoots from the roots so I’ll see how it goes.

Brianna planted in 2017 had died down it’s first winter or maybe vole damage. Regrew VERY vigorously and even set a little bunch. So I got a taste - very nice, larger than Prairie Star and possibly more flavor, sweeter (hard to tell with just a few berries). Unfortunately, about 3/4 winterkill this year. Will let grow what there is and hope it somehow gets hardier as it gets older.

Somerset Seedless planted in 2017 was girdled that first winter. It’s a much more sedate grower than Brianna (thankfully) and it regrew nicely. Healthy, very little leaf problems. This year most of it winterkilled except for a few low buds, which leafed early (compared to the others) and froze with the 24 deg June4th. Live buds from ground level and below growing. It’s still young so I certainly haven’t given up on it.

King of the North I dug out last fall. Just way too vigorous for my setup and though prolific doesn’t ripen all that well. And it’s a rather sour grape. Bluebell is similar ripening (as in, only the best years) but it’s a larger and better grape for me. I was going to replace with another Bluebell but instead transplanted a 2 yr seedling (from seed) Prairie Star I had growing in the nursery. Top all winterkilled but has 5 low buds or below ground shoots growing.

So not the best winter for the vines but there’s enough good buds growing to keep me ever hopeful.

Hi Sue. Have you considered any of the other Minnesota varieties like Itasca? Too many buds on a vine the previous year can compromise winter hardiness but so can many other things like late season mildew, trunk diseases, or vole/tractor/physical damage.

Petite Pearl should be able to ripen there as well.

Yes, both Itasca and Petite Pearl are on my consider list but there is only room for 6 where the grapes are (and that’s enough for us) so someone has to move out before someone gets to move in!

We’re on the far edge for grapes so it is a balancing act to find that best spot for protection-air cirrculation-sun, and where there isn’t already something planted. Guess that’s true for most of us growing on the edges. Sue

in bismarck my Marquette came through fine with no noticeable damage. actually all my grapes did well which surprises me. we had an unusually cold winter. i lay my seedless vines on the ground and covered them with leaves and they all survived also. gonna b a good harvest for me this year unless tragedy strikes… looking forward to trying vanessa for the first time!

Frontenac Gris fruited for me for the first time this year. They are very small and seedy but have a very nice flavor! I think they’d make excellent juice. They’re traditionally a wine grape but I don’t drink.

Derek do you have any problems with die back on reliance where you are? Do you lay your vines down in the winter?

i do lay them down. if i don’t they die back lot. I’ve had luck with reliance and Vanessa for seedless types.

This year’s grape harvest certainly doesn’t have bragging rights, hardly worth mentioning in fact. Lot of winterkil so early on figured they were a bust (lesson learned - never underestimate your plants!). But to my surprise, late but significant, a good number of buds grew. Hope! Then the first May freezes (teens-20’s) hit. Oh well, maybe next year. But they felt different. Secondary buds grew! Scattered throughout the vines but enough. When the second hard freezes came (we had record cold May) I decided to cover. But when I was done covering the garden the second night I forgot the grapes. Obviously lost again. Darn! And considering the record heat this summer it could have been a decent ripe. But the vines didn’t give up - thirdiary buds grew and these never-give-up vines set a small crop. These late comers did their best but just not enough time. When an early hard freeze was forecast a few days ago (24 deg) I decided there weren’t enough near ripe to cover so I harvested what I could find. Picked out the ripest grapes and juiced with plenty of sugar and some apples. Got 4 1/2 pints which was OK for such a rough year.

Marquette was the winner with the most ripe and near ripe berries. It thankfully has recovered from the vole damage a few winters ago. Sommerset tied with Marquette. I’m SO thankful to Jesse and others who recommended this variety. It’s low vigor and small vine but the grapes sweeten early. I ate all the ripe ones off the vine but still had some for the pot. I’m going to plant another Sommerset.

Prairie Star was close and is still a keeper for me even though I didn’t get much. It came through the difficult winter in good shape. Bluebell just had a handful of barely ripe but I still think its worth it for the good years. Brianna is coming out this fall (to be replaced with a second Sommerset). It was with Bluebell with very few even close but mainly it is just too vigorous for my spot and my vine continues with some leaf issues. In a warmer location I’d still recommend those two though, both for berry size and flavor.

So not a great or even good grape year but it did give me a better appreciation for the vine’s persistence and desire to grow and produce. On to next year! Sue

Do you have any Muscat flavored grapes?
I have a Viognier hybrid with some Elmer Swenson’s grape.

I got to try a few Lorelei (ES 5-4-29) this year. They seemed to ripen around the time of Somerset if I remember correctly. Very good flavor. A light Muscat flavor was present, and the other flavors were excellent, very fruity. Had more of a melting texture than other grapes. This was the first year fruiting so I only had about 5 grapes. Edelweiss is similar and maybe earlier, but it has no real Muscat flavor and the texture is more normal. It does, however, have a nice fruity flavor. I got my Lorelei from Double A Vineyards. Edit—> I just checked and Double A doesn’t have Lorelei listed for sale right now, hopefully that will change.

Here’s one (somewhat short season grape) from Canada (Ontario) that is quite interesting imo.

Rene Blanc
-White/green/golden color
-Non slip skin, medium thickness
-Seedless
-Grapefruit/lychee/cotton candy aromas
-Very sweet

But, uneaven ripening (not sweet and grass aroma when not fully ripe).

They ripen from the end of august until the end of september, for me, here in Qc 4b.

I’m really interested in Early ripe muscat grapes, but need an American source.
Our winters are very mild, so hardiness is not much of a problem.
That Cotton Candy flavor grape sounds good.

Ever heard of Herb Fritzke?
He selected a few very good wild riparia grapes.
The L-50s was one of the best.
He lived near Saint Paul, Minnesota
Wish I could get one of those.

Hi! Do you have any sources/infos/links on that grapes (L-50s) ? Sounds interesting. We have lots of Elmer’s Swenson grapes available in Can, so who know about that one.

Herb Fritzke is dead.
But the L-50S grape must still be in Minnesota especially among Grape breeders.
I used to have one, but no more.
I’m also interested in getting it again.
