1. Brewing liquor is generally suitable for high-quality liquor with an alcohol content of 50 ~ 60 degrees. This white wine can kill germs, harmful microorganisms, parasites and eggs attached to Chinese herbal medicines to a great extent during soaking, so it can be drunk under safe conditions.
2. If the concentration of wine is too low, it is not conducive to the dissolution of effective components in Chinese herbal medicines, thus affecting the treatment and health care effects. In addition, the concentration of wine is too low, which is not conducive to preservation. However, using high-concentration liquor, even if the medicinal materials contain a small amount of water, liquor is not easy to deteriorate.
3. Many people think that liquor should be soaked for more than 1 year, and the longer the time, the better. But most people think that the time of soaking wine depends on various conditions, such as temperature changes, and cannot be generalized. Generally speaking, the time is about 15 ~ 30 days. At the same time, during the soaking period, it is necessary to shake or stir once a day and stir once a week after 7 days. In order to fully soak out the active ingredients, the time can be a little longer.
