Harvest Notes

I started to get reports of the Iowa grape harvest starting with Edelweiss around August 15th in southwest Iowa. This is about 1 week later than a normal year. (Whatever that is!) The following week, reports of more Edelweiss and some Leon Millot were being harvested. This week and holiday weekend will see Brianna, Geneva Red, Niagara, Marechal Foch Seyval and even some Frontenac being harvested. Our recent heat wave has really increased the ripening rate over the last 10 days. Everything is starting to ripen all at once. This is causing a labor shortage problem for some vineyards.
Our very cool and record wet spring caused very poor pollination problems in many vineyards all across Iowa. Our grape crop will be smaller because of the many unfilled grape clusters. I am very surprised at the amount of high quality disease free fruit we have hanging on the vine this season. I know that most vineyards were not able to follow a timely fungicide spray program in May and June due to Iowa’s record rainfall amounts. I was all prepared to be answering calls about anthracnose, black rot and downy mildew all of July. This did not happen. Even some of our more disease susceptible cultivars escaped the disease bullet this year. I think there are three main reasons our disease pressure was low this season:
1. Grape pollination occurred 10-14 days later than normal ending just before the time the rain quit falling in the last week of June. There was just less time for diseases to affect the early forming fruit.
2. The VERY, VERY, VERY low disease pressure created by the drought last year created a MUCH, MUCH, MUCH lower pool of disease inoculum carrying over into 2013.
3. The very loose clusters from our poor spring pollination created a lower potential of diseases establishing themselves within what would be typically tighter clusters.
And finally, it looks like most of the Iowa growers have found a home for their grapes. I have received very few panic calls this year asking for help in marketing grapes.
Overall, I think we are going to have a crop of fair quantity and high quality this season with the outlook of good harvest weather. mlw

Saba Grape Syrup

Centuries ago, when refined cane sugar was a luxury for the rich only, the commoners made sweeteners by concentrating the juices of grapes and other fruit into dark, viscous syrups with a touch of acidity. Fruity in flavor, saba is mildly sweet. In ancient times, saba and honey were the only sweetening ingredients that were easily obtainable.
In Italy, these sweeteners are made from wine grapes and go by regional names like saba, sapa, vin cotto or mosto cotto. Vin cotto means ''cooked wine'' though it is made from unfermented grape juice, or must, and contains no alcohol. In southern Italy, vin cotto is sometimes made from figs. In Turkey, a syrup called pekmez is made from grapes or pomegranate juice (sold as pomegranate molasses) and is more acidic than saba.
Saba is a syrup made from freshly squeezed grape juice. The grape juice is cooked very slowly for a long period of time until it has a syrupy consistency. When it is slowly cooked into a syrup, it develops into a very rich, concentrated product. It can be used for many things: as a glazing dip, concentrate added to sparkling water, over shaved ice, over ice cream, as a sweetener in sauces or in salad dressings and a sweetener for baked goods.
Periderm: A secondary covering called the periderm begins to forms on the grape shoots at veraison and proceeds through fall. Periderm formation starts at the base of the shoot and moves outward towards the tips. The periderm replaces the outer layer of epidermis, and acts as a protective water repellent covering. The mature cells have suberin in their walls to protect the stem from desiccation and pathogen attack.

SWD’s Have Arrived

Spotted Wine DrosophilaSpotted Wine Drosophila has arrived in Iowa. Unlike most other vinegar flies that require damaged fruit to attack, SWD causes damage when the female flies cut a slit and lay eggs in healthy fruit. These small flies love to lay eggs in grapes and many other soft skin fruits. Learn more here in "Spotted Wing Drosophlila Arrives". 8-30-13 – IowaProduce.org E-Newsletter:
