Survey of Winter Damage in Okanagan and Similkameen Vineyards

The low temperatures experienced in late December 2008 and early January 2009 in the southern interior of British Columbia presented a unique opportunity to study the winter hardiness of commonly grown V. vinifera wine grape varieties. The rare combination of near-lethal threshold temperatures, an established temperature-monitoring network, and a large number of variety blocks within the monitored area created a rich source of data for the study.
