Ontario program will help grapegrowers protect vineyards.

St. Catharines, Ontario — If you are a grapegrower, do you know how acclimated your vines are to the cold? Soon, grapegrowers in Ontario will have a new tool to help them understand the cold hardiness of their vines and determine when to use their wind machines to protect their grapevines against winter injury.

Researchers at Brock University’s Cool Climate Oenology and Viticulture Institute (CCOVI) in St. Catharines have developed a database called VineAlert to provide growers with information about the level of grapevine hardiness for different varieties at different locations during the dormant season.

Sampling will take place throughout the dormant season—from vine acclimation in the fall to maximum hardiness in winter to de-acclimation in the spring. Starting this fall, samples of Chardonnay and Cabernet Franc, the most widely planted white and red vinifera varieties, will be taken within the 10 sub-appellations of the Niagara Peninsula from late October to mid-April. As the project gets underway, other grape varieties will be added, and the sampling extended to Lake Erie North Shore and Prince Edward County.
