More than 97,000 gallons of red wine spilled from a tank at a vineyard in Sonoma County and eventually leaked into the Russian River, which officials said could hurt water quality in the 110-mile tributary flowing into the Pacific Ocean.

The Cabernet Sauvignon, enough to fill eight large tanker trucks, spilled at the Rodney Strong Vineyards in Healdsburg on Wednesday after a door near the bottom of a large blending tank popped open, releasing all of the wine it was holding into a sanitary sewer system on the property, the Press Democrat reported.

The wine spilled into a drainage ditch that feeds into Reiman Creek and eventually made its way to the Russian River.

The winery is conducting an internal investigation and cooperating with authorities, Rodney Strong spokesman Chris O’Gorman said Thursday.


“We are deeply concerned and are doing everything in our power to protect our waterways,” O’Gorman said.

According to the Governor’s Office of Emergency Services, which was notified of the accident on Wednesday, about 20% of the 97,112 gallons spilled were contained. Estimates showed anywhere between 46,000 and 96,000 gallons reached the Russian River.

The Sonoma County Sheriff’s Office helicopter determined the wine reached as far south as Riverfront Regional Park within a matter of hours.

Rodney Strong contracted with two vacuum truck operators to clean up the spill, and tried to assemble a dam in the creek, Elson said. The containment measure was unsuccessful, since water was flowing faster because of the recent rains.
