292: Testing Vinifera vs. Hybrids: Which Survives Climate Stress Better?

Sustainable Winegrowing

Show Notes

Will hybrid grapes help vineyards survive climate change? Professor Karine Pedneault of the Université du Québec en Outaouais explores this question through trials that expose grapevines to drought and heat stress. Testing both vinifera and hybrid varieties, her research measured plant water flow and metabolic responses to determine resilience. While hybrids still carry a stigma around flavor, they showed promising resistance, raising the potential to reduce fungicide use by up to half and adapt more sustainably to extreme weather scenarios.

When we talk about sustainability in wine, practices like conserving water, enhancing soil quality, and supporting biodiversity often come to mind. But sustainability is about more than caring for the land; it's about caring for the people behind every bottle.

Healthy soils are built through years of management decisions and sometimes rethinking old practices. Jim Lincoln, General Manager of Beckstoffer Vineyards in Napa Valley, shares how his approach to weed management has evolved from cultivation and herbicides to mowing, sheep grazing, cover crops, and no-till practices. Learn how these changes have improved under-vine soil health, influenced weed populations, and affected costs. Jim discusses the real-world tradeoffs of building soil health and the opportunities it creates to improve fruit quality.
