(NBCNews) -  Sonia Byck-Barwick couldn’t fall asleep. It was a windy October night, and the electricity in her home in Northern California’s wine country flickered.

Sometime after 1 a.m., the facilities manager at Paradise Ridge Winery, which she co-owns with her father and siblings, called. A fire was approaching the winery, he reported, and Byck-Barwick’s husband, the winemaker, attempted to drive to the property. There’s fire everywhere, he said in a phone call from the road.The Round Barn, an iconic landmark that was built on Fountaingrove in 1889, burned to the ground. Also gone: the buildings of the adjacent Paradise Ridge Winery, which had housed an exhibit about Nagasawa, who had been known in his time as the “Wine King” of California both locally and in his native Kagoshima.

Still, she held out hope. “We still had hope because our buildings were made out of stucco and had tile roofs. And, you know, you always have hope, right? You try to have hope,” Byck-Barwick said.

The Tubbs Fire, which began the night of Oct. 8, 2017, would turn out to be one of the worst fires in California history, burning more than 110,000 acres and destroying nearly 7,000 structures.
