Where can I sell my grapes?

 
"Where can I sell my grapes? I get this question often this time of year and wonder why people wait until right before harvest to start marketing their grapes. There still is a strong market for winegrapes in the Midwest, but the industry has matured. Most vineyards start marketing their grapes prior to the start of the season or early in the season. Many of the wineries have already made their purchase commitments. That said, here are ten grape marketing tips to consider:
 
Ten grape marketing tips to consider:
 
1. The list of Iowa wineries open for business and their contact information can be found on the Iowa Wine and Beer Promotion WWW site: http://www.iowawineandbeer.com  Give the wineries a call or e-mail them. The prices per ton typically paid delivered to the wineries will normally fall in the $900 to $1,200 range. Sometimes the price is higher, but typically these are for excellent quality grapes of limited supply. Quality, quantity and cultivar are the primary determining factors of prices paid by wineries. Access to refrigerated storage, flexible delivery times and handling methods can also enhance the price.
 
OR
 
2. You can do a WWW search for wineries in neighboring states and let them know that you have grapes for sale. Yes,.. wineries do buy fruit from other states!
 
OR
 
3. Get the word out to hobby wine makers in your area. Typical prices paid to U-Pick self-serve winegrape vineyards will typically run in the $0.75. to $1.00 per pound range depending on quantity purchased. Location, quality and cultivar selection will be the primary factors determining the price. Some operations provide and/or sell 5-gallon food grade buckets. Selling by the 5 gallon bucket (approx. 18 to 22 lbs.) would eliminate the need to have a state approved scale on site. Providing a hand crank crusher/destemmer and hand crank press will enhance hobby winemakers to purchase your grapes. The sky is the limit as to what you could offer. Developing a good e-mail marketing list of hobby winemakers is the key. There are a lot of hobby winemakers out there and they all need juice or fruit to make wine!
 
Examples: Two Rivers Winegrowers, NJ: http://www.tworiverwinegrowers.com/
HoneyFlow Farm, Dryden, MI: http://www.honeyflowfarm.com/vineyard.php
Lemon Creek Winery, MI: http://www.lemoncreekwinery.com/
 
OR
 
4. You can post your grapes for sale in the classifieds. Here are some on-line classifieds that may be of help:
 
a. Illinois Vintners & Grape Growers Association. classified ads:
b. Northern Illinois Wine Growers Association classified ads:
c. Missouri Grape Growers Association Discussion Forum:
d. Iowa Wine Growers Association Classifieds:
e. Minnesota Grape Growers Forum:
f. North Dakota Grape Growers Association "Swap Shop" :
G. Wisconsin Grape Growers classifieds:
 
5. Sell your grapes to a wine and/or juice supplier. A convenient list of these suppliers can be found here on the Missouri Grape Growers WWW site: http://www.missourigrapegrowers.org/resources/wine-juice.php
 
OR
 
6. Store your grapes in a cooler. The length of storage time grapes can withstand before deteriorating can vary from 1-3 months depending on variety and storage conditions. I would estimate that most of our grape varieties could be held in cold storage for a maximum of 6-8 weeks at a temperature of 30-32°F and a relative humidity of 92-96%. Chapter 22 of General Viticulture, a book by Winkler, Cook, Kliewer and Lider is a good read for those interested in cold storage of grapes.
 
OR
 
7. You can freeze your grapes for a later sale date. Normally, grapes can be frozen for maximum of 2-3 months without freezer burn occurring but they will lose some of their color and taste. You may want to freeze in 5 gallon pails (approx. 18 - 22 lbs.) These pails will be much easier to thaw and sell to those who want small quantities. Vacuum packing could be considered if you need to store for a longer period and want to preserve freshness and eliminate freezer burn.
 
OR
 
8. You can press the grapes and store the juice and/or must in cold storage as a liquid or frozen solid. You would be required to be licensed as a food processor to do this. In addition, you will need to comply with FDA regulations. Suggest contacting Dr. Angela Laury, our ISU Extension Food Safety Specialist for further guidance on this: angelaml@iastate.edu or 515-294-0868.
 
OR
 
9. You can sell them at your local Farmers Market. Here is the Iowa Directory of farmers markets: https://www.idalsdata.org/fmnp/index.cfm?fuseaction=main.formFarmersMarketDirectory
 
OR
 
10. Sell them on Craigs List: http://www.craigslist.org

Harvest Timing

 
This season’s grape harvest has had us all guessing. We knew it was going to be early, but did now know how early. Well, we now know. Some vineyards and wineries in the southern half of Iowa will begin harvesting Edelweiss in the 14 to 16° Brix range this weekend. About 2.5 weeks ahead of schedule!
 
The optimum time to harvest grapes depends on the growing season, site, crop load, cultivar and intended use. The lighter the crop load, the quicker the ripening process. The timing of the harvest season will vary each year depending on environmental conditions. Soon after veraison (berries begin to turn color) and the ripening process begins. Acid content starts to go down, pH slowly rises, red grapes increase in color, white grapes turn translucent yellow to gold, sugar content goes up and aromatic and flavor compounds increase. In most cases, wineries will provide detailed parameters for many of these harvest values. The pH requirements are probably the most important for a winery because high pH’s are difficult to correct. Sugar content (ºBrix) and acidity can easily be amended. The generally accepted range of values for winegrapes at harvest would include:
 
Type of Wine
ºBrix
(%soluble solids)
Titratable Acidity
(grams tartaric acid/liter)
pH
Sparkling 17.0 - 20.0 7.0 - 9.0 2.8 - 3.2
White Table 19.0 - 23.0 7.0 - 8.0 3.0 - 3.3
Red Table 20.0 - 24.0 6.0 - 7.5 3.2 - 3.4
Sweet Table 22.0 - 25.0 6.5 - 8.0 3.2 - 3.4
Dessert 23.0 - 26.0 5.0 - 7.5 3.3 - 3.7
________________________________________________________________________
* Table 16.1 - Generally recommended ranges of soluble solids concentration, titratable acidity and pH in wine grapes at harvest for generic wine types. p. 288 Winegrape Production Guide for Eastern North America
 
Some grape cultivars don’t follow these guidelines and become and exception to the rule. An example would be Edelweiss which is usually picked between 14- 17 °Brix to keep the herbaceous (foxy) flavors low. Many of the American table grapes (Labrusca species) are picked in the 14 to 18°Brix range to keep the herbaceous flavors low and prior to the grapes deteriorating and falling off cluster. Table grapes are often considered ready when the sugar/acid ratio reaches 15 or higher.
 
These parameters are all very important. But,…. some winemakers are starting to put as much or more emphasis on taste, aromas and the presence of mature brown seeds to determine full maturity for harvesting. Adverse weather, birds, bunch rots and access to harvest labor will often make for the final determination.
 
Obtaining a representative berry sample prior to doing the analysis is VERY important. Procedures for taking a proper berry sample can be found in Wine Grower News #97 here:

Véraison is a French term that has been adopted into English.

The official definition of véraison is "change of color of the grape berries." Véraison signifies the change from berry growth to berry ripening. The berries become soft and take on the colors characteristic of their specific cultivars.
 
From the beginning of veraison to harvest, the berries will increase in volume, weight, and sugar content (brix). It is also identified as the 35th stage of 47 of the Eichorn-Lorenz Stages in Shoot Development
