Tentang bahan ini
White-koji mold (Aspergillus luchuensis var. kawachii) — distinct from the yellow-koji of sake and miso, and from the black-koji of awamori. Discovered in Kawachi (Kagoshima) in the early 20th century, shiro-koji enables citric-acid-pathway fermentation that suits warm-climate honkaku shōchū production. Commercially supplied by the Akita Konno Shoten and other specialist starter-culture (moyashi-ya) producers. Distinct from existing shio-koji and amazake (which are koji-derived foods, not the starter mold itself).
