About how many persons use?


There is not a problem by using of a five-person family every day with U-25 type. 100 times use with U-50 type and 50 times use with U-25 type can be performed , and it can respond also to many and unspecified persons. However, we recommend you to add sawdust temporarily, using many men in many cases beforehand. (It is for improving fermentation conditions)
