The changing climate around the world has forced grape growers into leaving their comfort zone in search of different grape varieties that will tolerate heat, experimenting with new vititcultural practices and modifying how they make wine. It’s a revolutionary era that will preserve the industry and introduce consumers to new wines.

We recently interviewed Christopher Jackson, second-generation proprietor of Stonestreet Estate Winery, about how his family operation is adjusting. Jess Stonestreet Jackson and Barbara Banke launched the estate in 1995.

Located on Alexander Mountain, the vineyards are already facing difficult growing conditions even without climate change.

Jackson said, “Over the last two decades, the extreme of winegrowing on the mountain have continued to grow in intensity. In 2004, recognizing the challenges in achieving physiological ripeness and high stress to the vineyards, we began implementing regenerative farming practices that could mitigate the growing intensity of conditions and foster resilience of the land and vines.”

He said he has identified more rigorous rootstock and clone combinations to reduce the stress on the vines. But the producer also has planted drought-resistant varieties, such as assyrtiko, chenin blanc and malvasia blanca. How these grapes fit into future wines – as a blend or stand-alone – remains to be seen.

With disappearing sources of water for irrigation. Stonestreet added reservoirs on the mountain to capture the rainwater. Since 2008, water use across Jackson Family wineries has been reduced 43 percent.
