Role of The Koji Lid
Koji lid, commonly known as kojibuta, is a small container that has been used for a long time in koji making (the process of propagating yeast cell on steamed rice).
Koji making takes place in a hot and humid specialized room called Kojimuro, which takes 48 to 56 hours. However, due to the nature of the room, various parts like the center and corners, front and back, whether it's close to the ceiling or near the tatami floor, can have different temperature and humidity. Therefore, the rice is divided into small portions on this koji lid, and the lid placement is regularly moved to adjust the conditions of all rice to be the same in terms of temperature and humidity. By moving and reloading every 3 hours, all the lids that are stacked in the corners of the room are moved to the center, the lids that are in the back are moved to the front, the lids stacked in the upper row are moved to The lower row, and so on. By doing this, the yeast cell will be uniformly propagated in the rice grain.
Advantages of koji lid method
Compared to machine-made koji (manufactured by automatically controlling the heat generation of koji), the finish of koji is much better. That is all. Even in sake breweries, when it comes to sake that are in junmai or ginjo classification, most of The breweries are made using this lid method. After all, there are some aspects in the world of brewing that are not yet understood by the power of science or machinery. Moreover, the finish of koji affects not only sake but also miso and soy sauce . The koji, which is in good quality even after the preparation, works well.
