Custom ferments target high-end kitchens
SAN-J, an 8th-generation Japanese brewery, has launched Bespoke Ferments, a partnership program designed to allow chefs at prestigious restaurants to collaborate on custom-brewed shoyu and tamari tailored to their specific menus.
The program targets kitchens already relying on SAN-J's traditional fermentation methods, including three-Michelin-starred establishments. Chef Keiji Nakazawa at Sushi Sho, for example, uses a private label SAN-J rice shoyu in his kitchen.
New online store expands retail presence
Alongside the partnership initiative, SAN-J has opened an online store featuring small batch, handcrafted brewed sauces with novel flavor profiles. The collection includes tomato tamari—made with sundried tomatoes and soybeans—alongside traditional rice shoyu offerings.
The moves reflect growing interest among high-end chefs in distinctive umami profiles and traditional production methods as differentiators in competitive fine dining markets.
Why It Matters
For operators seeking ingredient authenticity and customization, the Bespoke Ferments program offers a scalable model for collaboration with ingredient suppliers. The expansion of specialty soy sauce products also signals growing consumer demand for heritage fermentation techniques and unique flavor applications in elevated dining.
