This website is current as of June 15, 2018.In progress are trials of disease-resistant, cold-hardy grape cultivars grown under "no-spray" conditions in Eastern Connecticut to determine which cultivars are best suited for no-spray, or Organic cultivation.
Approximately 120 cultivars have been selected for these trials to be evaluated in the period 2010-2022 and the results shared on this website. Space is available for 137 vines allowing for more than one vine of some cultivars. As of this date 33 of the 120 cultivars have been rejected and dug out of the ground due to excessive disease under the "no-spray" conditions of this trial.
Grape cultivars of interest are those for jam, juice, table, freezing, storage, and wine.
This website has expanded to include tips on Organic gardening: fruit trees, microgreens, wine making. Also included is a listing of nurseries and which of the grape cultivars selected for this study they offer.

During these trials, grapes are being grown Organically without spraying of pesticides or fungicides (except for dormant organic spraying during the winter) to determine which cultivars do the best under these conditions. Most commercial grape growers have a sophisticated spraying program. If more disease-resistant varieties are used, money could be saved by less or no spraying. In addition, there are the added health benefits of a less toxic environment and product.
Furthermore, demand for Organic grapes and wines made from Organic grapes is increasing as consumers become awake to the adverse health effects of toxins and genetically mis-engineered crops (GMOs).
Grapevines will be evaluated for disease resistance, pest resistance, vigor, harvest date, taste, and productivity. However, the primary evaluation factors will be the production of healthy grapes and their taste.
Most grapes do not store well fresh; however, I have found 10 table grape cultivars that reportedly can be stored in a refrigerator for 6 months - what remains to be seen is which, if any, of these will do well Organically. On the other hand, all grapes store well frozen for about one year - a wonderful way to preserve your harvest.
Information will be added to this website as time allows. All photos are my own of the grapes produced in this study.
