Wine makers are pulling the cork on California.

Another giant in the world-famous wine growing region is shutting down and slashing staff, making it the fourth since the start of 2026.

Jackson Family wines has stopped production at its Carneros Hill facility in Sonoma’s Carneros region, laying off more than a dozen employees, according to a Worker Adjustment and Retraining Notice filed with California authorities on February 12.

Communications director Sean Carrol told theSF Chroniclethat Carnero’s Hill – previously owned by Buena Vista Winery – “served as overflow production capacity and was not tied to any specific brand.”

He added the site had “become underutilized,” allowing the company to consolidate.

Jackson Family Wines is known as one of the top US wine producers, the sixth largest wine company in the country.

It owns the Kendall-Jackson label and about 40 other brands, producing around six million cases a year, according to anindustry review. More than 25 of those wineries are in the Golden State.

Last week, major winemaker Galloannounced the closure of a large production facilityand the elimination of nearly 100 jobs across the wine growing region of Napa and Sonoma counties.

Considered the world’s largest winemaker by volume, Gallo filed a “warning” notice with the California Employment Development Department on Feb. 12, confirming it will permanently pull the cork on the Ranch Winery in St. Helena.

Gallo is also slashing staff at some of its other labels, including the Louis M. Martini Winery and the Orin Swift Tasting Room in St. Helena, as well as J Vineyards and Frei Ranch in Healdsburg.
