2021 Crop Outlook
Despite two late spring frost events on April 21 and 22, the 2021 crop is looking very good. The frost/freeze events mean that there likely will be shortages of some grape varietals. These include grape cultivars that do not or have limited crop production from secondary buds such as Concord, Catawba, Norton, and Chardonel.
I have had some people contact me looking for grapes and so the Grape Exchange is up and running. If you have grapes for sale, please contact Karissa King to get your grapes listed (see below).
Grape Exchange
The Grape Exchange on the Grape and Wine Institutes web page will begin to take listings of grapes for sale on Friday, July 16, 2021.
Please submit your Grape Exchange listing to Karissa King at kingkari@missouri.edu. Please submit the following information: varietal, tons, and contact information.
The Grape and Wine Institute also has an Equipment Exchange that includes equipment in the vineyard and winery. These items can also be submitted to Karissa King as above. Please submit the following information: equipment type, description, cost, and contact information.
