焼酎粕 (Shōchū-kasu)

Kyushu honkaku shōchū industry produces the world's only large-scale supply of imo / mugi shōchū kasu; heritage knowledge for upcycled active ingredient extraction.
Free amino acid 0.5–2% (wet basis); polyphenol content elevated in imo-shōchū kasu vs mugi.
Upcycled cosmetic moisturisers, fermented-supplement feedstock, regional-craft retail.
Liquid and solid residue from honkaku shōchū distillation. Long historically a feed/fertiliser by-product, recent research has identified amino-acid and peptide-rich active fractions with humectant and skin-conditioning properties. Kagoshima, Miyazaki, and Kumamoto — the heartland of imo (sweet potato) and mugi (barley) shōchū production — generate the largest volumes. Used in cosmetic moisturising lines and as a feedstock for fermented-supplement ingredients. Distinct from sake-kasu (rice/koji) in profile.
