Step 4: Water showering The time in the shower room is usually one day.

From the smouldering workshop, the raw materials enter the shower room. At this time, it is necessary to add boiled water to the raw material, and in the jargon of the vinegar, it is said to be "infused with vinegar." The bottom of the raw material is a large sieve, and the vinegar leaks out of the sieve and is drawn into the pan. If it is seasoned vinegar, it can be mixed with fennel, pepper, aniseed, etc. in the pot to make vinegar of different tastes. These new vinegars usually stay in the shower for a day.
