Farm-to-Ferment Miso, Shoyu & Umami Seasonings

Co-founders Eleana Hsu and Kevin Gondo making ferments in their old kitchen

Shared Cultures is a small batch fermentation company in San Francisco specializing in using koji to ferment newly imagined, farm-to-ferment miso, shoyu, and umami seasonings. Inspired by traditional fermentation methods, wild foraged ingredients, the bounty of Northern California, and our families’ pasts, we honor our cultural food traditions with a modern fermentation approach.
