After experiencing an exceptionally cold and persistent winter, local farmers are beginning to face the potential loss of crops. In the Ontario wine grape industry, experts indicate that it is still premature to determine the full extent of damage, but there are evident losses in Niagara-on-the-Lake and more significant damage in Lake Erie North Shore near Windsor and the U.S. border.
Quinton Jenkins, the owner of Jenkins Vineyards Niagara Inc., mentioned that the extreme cold, reaching as low as -19 degrees, has caused damage to the bud tolerance for frost, particularly for certified organic vineyards. He explained that bud death can occur around -17 or -18 degrees, prompting the use of wind machines to protect the vines by raising air temperatures.
Jenkins noted that the damage at his vineyard was primarily on the merlot grapes, with approximately 30 to 50 percent bud damage, which is less severe compared to the broader impact felt by many vineyards in the region during the winter of 2022.
Despite the challenges posed by the prolonged freezing temperatures, the Ontario wine industry remains resilient, with a commitment to ensuring the prominence of Ontario wines. Stephen Mitchell, vice-chair of Ontario Craft Wineries and owner of Sprucewood Shores Estate Winery, highlighted the varying degrees of damage across regions and vineyards. He emphasized that regions like Lake Erie North Shore are experiencing substantial damage, while areas like Prince Edward County, where winemakers took protective measures like burying vines, are expected to fare better.
Collaboration within the industry is crucial during times of damage, with winemakers supporting each other by sharing grapes to ensure continued wine production. As the industry navigates the challenges posed by the winter conditions, growers will gain a clearer understanding of the extent of losses in the upcoming spring.
Amid increased pressure and a surge in home-grown wine sales due to the U.S. trade war, Ontario winemakers are adapting to the shifting market dynamics. David Eiberg, the Founder of Therianthropy, a natural wine company, highlighted the positive shift towards supporting local producers and the recognition of Ontario wines on an international level. Jenkins, having already sold all his grapes, expressed optimism for the future of sales and the ongoing support for local producers.
In conclusion, the winter’s impact on Ontario grape harvests is being assessed, and the industry remains focused on overcoming challenges and maintaining the momentum of Ontario wines in the market.
