The grape and wine industry in North Carolina is now worth in excess of $30 million dollars. To assist North Carolina growers in the production of quality grapes for quality wines, a newly revised guide has been written for winegrape growers, called the North Carolina Winegrape Grower's Guide. This publication provides grape growers with practical information about choosing an appropriate site for a vineyard, establishment, and operation of commercial vineyards in North Carolina. It includes a new chapter on spring frost control and examines the pros and cons of active frost protection systems.
