Grapes
Grapes are an important fruit crop in Florida, where the warm climate and plenty of sunshine create ideal growing conditions. Unlike other traditional grape regions, Florida mainly produces muscadine grapes (Vitis rotundifolia) and disease-resistant hybrid bunch grapes suitable for the humid subtropical environment. The state’s longer growing season allows earlier fruit ripening than in many other U.S. regions. Although the grape industry is relatively small compared to other crops in Florida, it has been steadily growing and plays a vital role in supporting local wineries and value-added agricultural ventures.
The University of Florida has significantly contributed to the growth of Florida's grape industry. Grape breeding efforts started in the 1930s after European grape cultivars failed to thrive due to Pierce's disease, a bacterial illness common in Florida. Early breeders like Loren Stover and later Dr. John Mortensen focused on incorporating resistance from native grapes into quality bunch grapes. This work resulted in key cultivars such as ‘Lake Emerald’ and ‘Blanc du Bois’, the latter becoming one of the most successful wine grapes in the southeastern U.S.
UF also developed several notable muscadine varieties, including ‘Florida Fry’, ‘Southern Home’, ‘Delicious’, and ‘Southern Jewel’, which feature improved fruit quality and better adaptation to Florida’s climate. Recently, UF has renewed its efforts by evaluating historical breeding lines and creating new crosses with better disease resistance and fruit quality. These initiatives aim to produce cultivars that support a sustainable, profitable grape industry for Florida growers, serving markets for fresh fruit, juice, and wine.
