What we liked

  • + Described as keeping its white color with strong fermentation ability, useful for pale ferments like white miso.
  • + One 20 g sachet is rated for up to 15 kg (33 lb) of rice koji, enough for many home batches.
  • + Produced by Hishiroku in Kyoto and sold as a powder that is easy to measure out.

Trade-offs

  • - Only 20 g per sachet, so anyone making koji every week may prefer a larger pack.
  • - Very close to the Kairyou Chohaku-kin sachet from the same maker, so most kitchens need only one of the two.
