A worker was killed Monday afternoon at a Napa vineyard after getting stuck in a grape harvesting machine.

The Napa man was working near the machine at Deconinck Vineyards when his clothing caught in it, pulling him in and killing him, according to Chet Schneider, a spokesman for the Napa County Sheriff’s Office.

He was pronounced dead at the scene.

The vineyard, which is part of Beaucanon Winery, has had no prior worker safety issues, according to a database run by the California Occupational Safety and Health Administration. Cal/OSHA is investigating the incident.

Though worker deaths are rare in Wine Country, they are not unheard of. Last spring, a Fairfield man died when the tractor implement he was cleaning at a Sonoma Valley vineyard crushed him. He was found underneath the machinery at Arrowhead Vineyard.

The Sheriff’s Office could not confirm what type of grape harvesting machine the unidentified man was working near. Mechanical machines vary from the more basic type, which look like tractors, to expensive models that rapidly sort and de-stem the fruit.

And while there has been resistance to mechanical harvesting among high-end wineries, especially in Napa and Sonoma counties, which see hand-picked grapes as an essential component of their premium products, the machines are becoming more common. In 2017, about 80 percent of all California grapes were harvested by machine.

Deconinck Vineyards did not immediately respond to calls for comment.
