木桶醤油 (Kioke jōzō shōyu)
Kioke-fermented soy sauce is brewed in traditional Japanese cedar barrels (kioke, 木桶), some of which are over 100 years old and carry resident microbial communities.
MOQ from 200–1000 L (tank batch) / 20–100 L (bottled).
Premium bottled finishing soy sauce (export retail) — 'Craft soy sauce' positioning for premium retail in Europe, North America, and East Asia — small-format glass bottles with producer story and kioke production-method narrative on label.
La sauce soja fermentée en kioke est brassée dans des fûts traditionnels japonais en cèdre (kioke, 木桶), dont certains ont plus de 100 ans et hébergent des communautés microbiennes résidentes. La majorité des sauces soja commerciales modernes utilisent des cuves en acier inoxydable ; la production en kioke s'est réduite à un petit nombre de brasseries spécialisées, concentrées à Shōdoshima, Yuasa et Chiba.

Supplier-disclosed industry ranges are 200–1000 L for tank-batch supply and 20–100 L for bottled formats, with 8–16 week lead times. Because kioke production is small-scale and capacity is fixed by the number of operating barrels at each brewery, allocation to export buyers is typically through long-term relationships or trading-house intermediaries. Plan procurement at least 6 months ahead for any commercial volume.

Connaissance sectorielle — non encore rattachée à une source primaire unique
EU regulation sets a maximum 3-MCPD limit for soy sauce (currently 0.02 mg/kg in liquid; equivalent calculation on dry matter basis applies) under Commission Regulation (EC) No 1881/2006 and successor regulations. Reputable Japanese producers, including kioke shōyu specialists, can supply COA confirming compliance with the EU limit. Allergen labeling for soybeans and wheat is required for EU and US markets.

Most kioke producers focus on koikuchi (regular dark) shōyu, but some also produce tamari, saishikomi (twice-brewed), and other regional varieties using the kioke method. Saishikomi is notable as a more concentrated, slow-aged style sometimes called 'sashimi shōyu.' Specify the variety at RFQ — the kioke method is applied across multiple shōyu types and the production-method positioning translates across them.
