The production of greenhouse grapes is a very uncommon but historic concept. Although rarely found, Vitis riparia ‘Frontenac’ would be a good cultivar for greenhouse production due to its large resistance to root Phylloxera and winter hardiness. For these reasons, winter costs of a greenhouse would be lower than those for other crops that are harvested year-round. Greenhouses would have better protection from other pests that affect ‘Frontenac’ grapes in the vineyard, such as leaf Phylloxera and Botrytis. The following paper goes to explain why growing ‘Frontenac’ in greenhouses would be both cost-efficient and sustainable.
