Growing Grapes For Wine In Uk

Prairie Yard Garden Growing Grapes

(gentle music) Prairie Yard Garden is a production of the University of Minnesota Morris in cooperation with Pioneer Public Television. Closed captioning is provided by Mark and Margaret YackelJuleen in honor of Shalom Hill Farm, a nonprofit rural education retreat center in a beautiful

prairie setting near Windom in southwestern Minnesota. Shalom Hill Farm, shalomhill Did you hear that a new crop is appearing on the prairieé Growing grapes has created an interest among a few individuals who like the challenge of adapting it to our region. Join me on Prairie Yard Garden as we visit a vineyard to learn about the process and challenges

of growing grapes on the prairie. (soft lighthearted music) A new crop has appeared on the prairie: growing grapes And today I have Florian Ledermann with me who's been involved with the process for the last four to five years. Florian welcome to the show and tell me, how did you get interested in growing grapesé ^We got interested actually at the

University of Morris's Horticultural Night. We sat down in a tent and learned that the university just released four new varieties of grapes that are actually coldhardy. And before that, I always kind of figured grapes were the crop that just kind of came up and never really bore and died every winter and died back. So that's what spiked our interest.

And so that very nextspring, we bought five. And they survived and I did a little more research and decided to go with an acre. And a year later, another acre so we ended up with 1,350 vines as a result of that little adventure in Morris. Larry That's interesting. 1,300 vines, how long does it take you

to put all those in the groundé Florian We used family labor. (Florian laughs) So we had, it took us, I think probably when we were planting, it took us about threedays to put one acre in. That would be for the planting. The posts and the trellis system and everything

Caring for Young Grape Vines

My name is David Handley, I'm with the Universityof Maine Cooperative Extension, and we're here to talk about how to prune and traina young grapevine. This is a vine that was planted last spring. We got it from a dormantplant, or rooted cutting, and you can see the original part of the planting right here.This is what we got from the nursery, with a good root system under it. We planted it,and we had a bud break and some vine growth. This is last year's growth right here. Thiswas a green shoot. Typically, you may get more than one shoot developing. You may haveseveral buds on here. We want to prune this back to one strong vine, your strongest one.We're going to arrange for that to be tied

up to a trellis, because this particular vineis what's going to become our permanent trunk, or the permanent part of the plant that'sgoing to be with us for the life of the planting. We want to make sure it's the strongest ofthe vines that we can choose from. Any other one that developed that's very weak, we canjust cut that out, select our best one. The time of year to make these cuts are whenthe canes are dormant, and this is going to be really any time after the new year, untilthey bud out in late March, early April. We hope in the first year that we get enoughgood growth that we can tie it to the lower trellis wire.Typically here in Maine, we're going to be

pruning to either a four arm kniffin trainingsystem, or an umbrella kniffin training system. Those trellises consist of two wires, oneset at about two and a half feet, and a second wire set at about five feet.We hope in the first year that we're going to get enough good growth to reach at leastthe bottom wire, but in order to make sure it's growing straight, you can see we supportedthis with a small bamboo pole. Any kind of planting stake will work, and we just tiethat vine up as it grows, rather than let it grow along the ground where it can getrot problems, and not develop a nice straight growth like we want. We tie it up, just likeyou'd tie up a beef steak tomato, get the

growth that you want.As I said, we've got pretty good buds here, reaching up to the first wire. You can seethat I actually make it to the top wire, but you can see the growth up here is very scrawnyand spindly, and isn't really going to lead to a good, strong trunk. I'd rather actuallystart new growth for reaching to this top wire for next year.What that means is that I'm actually going to cut this off here, rather low, to try toget this bud here to break and give me a much stronger shoot to develop my trunk to thetop wire next year. I can just take that there, and then, instead of using the bamboo polethis year, I can just tie it to the wire.

This bud will hopefully break, and give mea good, strong shoot, that I'm going to reach the second wire next year. Of course, thesebuds lower down will also break, and if this one happens to be weak, I may select one ofthese. But, if this bud does turn out to be a strong shoot, I'll be cutting these offnext winter and getting my single trunk back up to the top wire.Next year, when this does reach the top wire, eventually what we'll be doing is taking oneyear old cane, and either draping it over this top wire and connecting it to the bottomwire in an umbrella kniffin, or we'll be taking one cane at the top wire on each side, andone cane at the bottom wire on each side,

to create four arms of one year old growth,for a four\uc0\u8209 arm kniffin system. Both systems work pretty well for concretetype grapes here in a cold climate like Maine.

The unique climate of the Rheingau for growing wine grapes

It means that we have never very cold wineters. By far not as cold as Chicago or New York We are crying it is cold if it is 10 degrees. But that's not really cold. We are never too hot in summer. Your summer (in Chicago) is much more hot than our summer. We have very long vegetation period We have leaves on the trees until theend of October beginning of November The leaves on the vines.

Grape picking happens here the in the middle of October until the endof October sometimes even November. California they start grape picking in August andrun through September. In California when they pick grapes its during the day pretty hotinto a white warming up of the grape must and the berries at harvest

they a pick the grapes during the night, the cool of the night. We do not need that. When we pick our grapes, sometimes we need a warm sweater And now it comes to the microbiological biology. The biological conditions are very different whether you have a fruit what's this, the squeezed fruité (must)

fruit. If you have fruits harvested at 30 degrees celsius, 35 degrees, then there from the very beginning ofpicking the yeast and all the microbiological are very active. If it is cold from the very beginning when you pickthe grapes and it goes cold into the into the press and the fresh juices

pretty cool, then the process isvery slow and that keeps aroma that keeps afreshness that keeps the acidity, so because of climate the production and fermentation of grapes and conversion into wine is in a different scale. We do not need cooling facilities no, nature does it.
