“A lot of people are contacting me from around the world hearing all these terrible stories, but actually the vineyards are not impacted at the moment,” Croft, a tour guide based in Bordeaux, told CNN. “But we’re all very upset because there are people losing homes.”
Croft said at this time of year, the grapes aren’t yet large enough to absorb wildfire smoke – a phenomenon known in winemaking as “smoke taint.”
“We won’t be harvesting until the beginning of September,” Croft said, “so there’s still time.”
Dr. Phil Crews, a winemaker and chemist at the University of California, Santa Cruz, explained that unripe grapes aren’t as vulnerable to smoke taint. Young grapes lack sugars that would otherwise bind with bitter-tasting phenols in wildfire smoke.
“If you don’t have the sugars in the pulp of the grapes,” Crews said, “you don’t have the problem.”
