Even the wineries where buildings survived may see damage to crops.

Any of this year's harvest still in the fields is threatened not only by flames, but also by smoke, which can ruin grapes that have not yet been picked. Still, most of this year's crop was already picked and next year's fruit won't likely be affected, Anita Oberholster, a cooperative extension specialist in enology at the University of California, Davis, told the AP.

"Even if wines now were heavily affected by smoke, it doesn't carry over to the next season, only in the fruit itself," she said.
