(PD) - A fire sparked by staining rags badly damaged at a Windsor winery warehouse Tuesday night, a Sonoma County Fire District official said.

The blaze at Notre Vue Estate Winery and Vineyard on Hillview Road was reported about 8:40 p.m. Firefighters found flames outside and in a portion of the 11,000‑square‑foot building when they arrived, said Cyndi Foreman, spokeswoman for the fire district.

The fire appeared to have started just outside the building that houses a tasting room, offices and a warehouse where wine barrels are stored and spread to one area inside, but there was smoke and heat damage throughout, Foreman said. The blaze caused about $500,000 in damage to the building.
