Commercial wine grapes have recently emerged as an alternative crop in Kentucky after laws evolved encouraging private entrepreneurs to invest in vineyards and small farm wineries many decades after prohibition shut down the industry. Grapes grown in Kentucky are exposed to biotic and abiotic stresses that reduce crop yields and quality or kill grapevines. Damaging winter temperatures, spring frosts, and higher than optimal growing temperatures occur regularly. Despite these challenges, grape growing is a successful enterprise in many areas of the state.
