Temecula Wineries Adapt as Climate Change Impacts Vineyards
Triple-digit temperatures are putting vineyards to the test in the Temecula Valley, and winemakers say climate change is forcing them to adapt.
At Akash Winery, some grape varieties are already entering veraison, the stage when grapes begin changing color as they mature.
Wine expert Cliff says an unusually warm start to the year caused vines to emerge from dormancy earlier than normal, accelerating the growing season and pushing the harvest ahead of schedule.
"We hit 100 degrees in March," Cliff said, noting that temperatures reached triple digits while it was still technically winter.
Winemakers say rising temperatures, persistent drought conditions and longer heat waves are becoming increasingly common challenges for vineyards not only in California but around the world.
Similar concerns are being felt south of the border at Adobe Guadalupe Winery, where winemakers are also adjusting to extreme weather conditions that can affect grape development and overall wine quality.
Experts say excessive heat during key growing periods can impact sugar levels and seed development, ultimately affecting the flavor profile of the finished wine.
For many in the industry, adapting to changing conditions has become an essential part of modern winemaking as vineyards search for new ways to protect vines and preserve the quality of each varietal.
