General requirements for traditional koji wheat ground into "rotten heart is not rotten skin" plum petals, leather upcoming wheat ground into flakes borders, foursquare pulverized . General koji with wheat about 13% moisture content , directly after crushing blocks with compressed into song koji , is not conducive to the growth of microorganisms .

Therefore, when the song spices billet must have sufficient moisture. Usually in raw materials ( wheat ) to the raw material before crushing "inflated ", that run wheat, causing water to reach about 30% ( with hot water in winter , in summer with cold water ) .

Is pre- mold, yeast blooms ; since the late song billet product temperature rises rapidly, generally more than 40 ℃ -45 ℃. Many wineries like to use partial Luzhou koji temperature 55 ℃ -60 ℃, it will force the yeast large number of deaths . Northwest Territories song now commonly used in low-temperature (40 ℃ -45 ℃). High temperature and low temperature Qu Qu index contrast.
