Melted wine bottles at Santa Rosa Winery.

Photographer Josh Edelson was documenting the fire damage from the wildfires at the Paradise Ridge Winery in Santa Rosa, California when he noticed the strange phenomenon.

Speaking to SF Gate newspaper,  Josh Edelson says he was walking the fire-ravaged grounds of Paradise Ridge Winery with the owner when he noticed a large plastic container, about three-feet-by-three-feet in size, that had once held wine and was completely melted.

“I saw a pool of wine and it was flowing lightly down the hill and as I got close to it, I noticed that it was bubbling,” Edelson says. “At first I didn’t understand it, but then it dawned on me that the ground was hot and the wine was boiling with all that stuff smoldering around it.”

 More than a dozen wildfires are still blazing in Napa, wiping out vineyards entirely.
