Vineyard owner David Hirsch was seriously injured this weekend in a tractor accident at his vineyard near the Sonoma coast.

The accident reportedly occurred while Hirsch was showing one of his workers how to operate a skid-steer tractor, a model used primarily for its large lifting scoop. He is in stable condition at Santa Rosa Memorial Hospital, according to one of his daughters, Jasmine Hirsch.

Hirsch underwent a single operation late Saturday night, which “went incredibly well,” Jasmine Hirsch said. The accident caused some skeletal injury, and cuts and bruises. But his daughter said there was no head injury, as previously reported.

“We’ve spoken with him, and he was making jokes with us after his surgery. He knows who everyone is around him and he’s really happy to have his family there,” Jasmine Hirsch said.

Hirsch Vineyards, located on a remote ridge outside Cazadero, has been one of California’s top sites for growing Pinot Noir. Hirsch, a former clothing entrepreneur, acquired the site in 1978 and began planting it a few years later at the suggestion of winemaker friends. By the 1990s, such top winemakers as Burt Williams from Williams Selyem and Ted Lemon of Littorai began buying Hirsch’s grapes, making the Hirsch name a familiar one to Pinot connoisseurs.

Despite the recognition, Hirsch has eschewed the fancier side of the wine business, preferring the hands-on work of farming. Since 2002, his family has made wine under the Hirsch Vineyards name in addition to selling grapes.

The family is optimistic about a recovery.

“He’s going to be back to telling us all what to do pretty soon,” Jasmine Hirsch said.
