Sake Lees Extract

Supplier-disclosed industry ranges are typically 10–30 kg with 4–8 week lead times. Sake brewing season runs October–April, so primary sakekasu supply for any given year is concentrated in those months; cosmetic extract producers typically buffer with stored sakekasu through the off-season but may quote longer lead times for premium single-brewery origin material.

Yes. Several Japanese fermentation-cosmetic specialists offer single-brewery origin sakekasu extracts, often from named breweries in Niigata, Nada (Hyōgo), Fushimi (Kyoto), or Saijō (Hiroshima). These typically carry premium pricing, lower MOQ ceilings, and longer lead times than aggregated-source material. For brands building 'craft fermentation' positioning, the brewery story can be a meaningful differentiator.

Cosmetic-grade sake lees extract is typically processed to remove or minimize residual ethanol, but the COA should declare residual ethanol content. For Halal-positioned export markets, alcohol content and source require careful documentation; Halal-certified sake-derived cosmetic ingredients are limited and typically require explicit certification rather than industry-general assumption.
