In order to reduce the content of aldehydes in liquor production, it is necessary to reduce the use of rice bran and husk, or to pre steam the auxiliary materials. In order to reduce the content of total aldehydes in liquor, the temperature of liquor flow should be strictly controlled and the end of liquor should be pinched.
The containers for liquor storage must be made of ceramics or glass. In a word, they can only be sealed well. The storage place and temperature are better underground, because underground is an environment with little temperature change, and they are basically kept at normal temperature
Liquor is a volatile substance, so it will not volatilize much. It is mainly to keep the original flavor of liquor without deterioration, which is also important. Generally, the storage time should not be less than three years, so the wine taste is pure, and the taste is particularly good.
The bottled liquor should be dry, clean, bright and well ventilated, the relative temperature is about 70%, and the bottle cap with high temperature is easy to mildew.
The ambient temperature of liquor storage should not exceed 30 ℃, and fireworks are strictly prohibited. The container shall be tightly sealed to prevent wine leakage and "running".
The bottle mouth of Kaifeng liquor is carefully wrapped with fresh-keeping film and wrapped with transparent tape. The tape is stretched straight and tightened at the bottle mouth position, and it is wound several times. The transparent tape has a characteristic
The longer the time is, the tighter the wrapping is. Do not forget to leave a section of tape head, or it will be difficult to dismantle. But the effect of this method is worse than that of sealing wax.
The unopened ones are also better preserved at zero centigrade, but the alcohol is volatile and will run away after a long time. The packaging of commodity wine is not suitable for long-term storage. You can seal the mouth of the bottle with wax and keep it for a long time
