"There are a lot of evacuations and closures going on throughout the valley. We are trying to just keep the roads clear for the firetrucks to get through. Because there are only two-lane roads through the valley. Smoke is everywhere. The smoke is very thick and very dangerous." John Taylor, the testing room manager of Yao Family Wines told Xinhua.

"We will be closed until further notice until we see how these fires go." Taylor said, adding that "It's only ten miles (17 kilometers) away from the closest fire. I have gone. I am not there."
