A short drive from Tsar Nicoulai, which also has an elegant cafe in San Francisco’s Ferry Building, Passmore Caviar in Sloughhouse has been, similarly, hard at work to establish the area’s reputation as caviar central. "The area provides resources optimal to the culturing of white sturgeon and also offers proximity to UC Davis and its renowned aquaculture program and caviar expertise,” says Michael Passmore, whose business is coming upon its 20th anniversary. "We really just focus on raising healthy fish that produce wonderful roe."
At the farm, the pristine, cool water of the region, which is being sustainably reused on site, flows from an aquifer—an underground pool of water that comes up to the farm spring via a pump, at 64°F. “Add to that the Mediterranean climate, which all result in an environment that is optimal for the native white sturgeon species,” says Passmore, explaining how they get a top-notch product with minimum intervention.
Compared to its neighbors, Passmore is a bit more boutique, and recently it was announced that Tsar Nicoulai had purchased Sterling, a third big-name producer in nearby Elvaretta, increasing its footprint in the area. The acquisition didn’t change the vibes much; the small-town atmosphere and the simple structures of the caviar plants feel far from the product’s glitzy reputation. Yet this is where many chefs and purveyors are looking to for sourcing, partnerships, and even creating their own private labels.
The most famous name in the game is perhaps the French Laundry’s Thomas Keller, whose own caviar brand, Regiis Ova, is produced by Sterling. In San Francisco, chef Matthew Accarrino of restaurant SPQR, has recently collaborated with another power player, the California Caviar Company. Led by well-known local figure Deborah Keane, the brand sources caviar from sustainable farms all over the world, and farms its own white sturgeon at CQ ranch in Elk Grove, CA, an 11-minute drive from Tsar Nicoulai. The brand also has an elegant tasting room in Sausalito, and a starry list of chef partnerships, which Accarrino was happy to join.
“I invested in understanding the principles and process of caviar making because it was a local ingredient,” Accarrino says of the pathway to create his own caviar label, ACCA. Motivated to “peel back the curtains and truly understand the where, the how, and the why of the process and product,” Accarrino, thanks to the proximity of the production plant, was able to participate in every step, from picking the characteristics of the initial eggs to processing the roe by hand to incorporating the final product into the restaurant’s dishes. “What's special about the caviar is that it is a local product,” he says. “In essence, this is a product native to the area.”
