Fuku-genryō

【English】
Subsidiary ingredients

Signifies raw materials for seishu other than primary ingredients such as rice, kome-koji and water. Although the term subsidiary ingredients (副原料 fuku-genryo) doesn’t occur in Liquor Tax Law, brewer’s alcohol, saccharides, organic acids and amino acid salts are commonly so called. Saccharides include glucose and mizu-ame (starch syrup); organic acids include succinic acid, lactic acid, malic acid, citric acid and such, and amino acid salts refers to monosodium glutamate.

Liquor Tax Law stipulates the raw materials for seishu to be “rice, rice koji, water, seishu kasu and other articles as designated by government ordinance”. “Other articles” corresponds to “subsidiary ingredients”. It is stipulated that the combined weight of these “other articles” may not exceed half of the weight of the rice (including kome-koji).
