University of Bordeaux to improve wine adaptation conditions with climate experiment

There are reports that the University of Bordeaux, France, is conducting climate experiments using Portuguese and Greek vines to help winemakers find ways to adapt to rising temperatures that cause an imbalance between sweetness, acidity and aromatics in their wines.

The average annual temperature in Bordeaux has risen by nearly 3.6 degrees Fahrenheit since the middle of the last century, according to French meteorological data, and a summer heat wave in 2019 has reduced French wine production by more than 10 percent.

For this reason, scientists are studying the microclimate of the Bordeaux region, and land on the northern slopes of the hills or on the cooler riverbanks may be a better location for wine growing.
