NASA Study Finds Climate Change Shifting Wine Grape Harvests in France and Switzerland
A new study from NASA and Harvard University finds that climate change is diminishing an important link between droughts and the timing of wine grape harvests in France and Switzerland. During a study of wine grape harvest dates from 1600 to 2007, researchers discovered harvests began shifting dramatically earlier during the latter half of the 20th century. These shifts were caused by changes in ...

First raisin grape that dries naturally on vine developed
Agricultural Research Service (ARS) scientists in California have developed a new raisin grape that dries naturally on the vine, making it unnecessary for growers to cut into the woody “canes” connecting the grapes to the mother vine weeks before harvest. For mechanically harvested raisin grapes like Thompson Seedless, growers have to cut the canes each summer, usually about 2 weeks ...

How policies could help winegrowers adapt to climate change
Grapes are sensitive to small changes in temperature, rain and sunlight, meaning climate change will have implications for wine producers worldwide. This study assessed local vulnerabilities and adaptation strategies in two wineproducing areas in France. The findings may help growers to develop suitable methods of adapting to long-term climate change. Changes to climate are already having ...

Purfresh Ozone Container Trials Show Promise for Smoke-Affected Winegrapes
Trials conducted during the 2020 harvest with smoke-exposed winegrapes using controlled ozone (O3) treatments in shipping containers indicate such pre-crush treatments can mitigate and reduce levels of smoke-related volatile phenol (VP) compounds from grapes and produce resulting wines with more favorable sensory and quality characteristics. Purfresh Wine of Hayward, California (formerly branded ...
