This website is current as of Feb 20, 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 to Organic cultivation.
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 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 more aware of the adverse health effects of toxins and genetically mis-engineered crops (GMOs).
Approximately 120 cultivars have been selected for these trials to be evaluated in the period 2010-2022 and the results shared on this website.
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 heathy grapes and their taste.
Most grapes do not store well; 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.
Information will be added to this website as time allows. All photos are my own of the grapes produce in this study.
