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.

白酒存放的容器必须是陶瓷或玻璃的，总之是封闭的好才行，存放的地点、温度较好是地下，因为地下是温度变化不大的环境，基本保持常温的

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

白酒是挥发性的物质，这样也不会挥发多少的，主要是保持白酒的原味，还不变质，这也是重要的。存放的时间一般应不少于三年，这样的酒味道才纯，口感特别好。

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.

瓶装白酒应选择较为干燥、清洁、光亮和通风较好的地方，相对温度在70%左右为宜，温度较高瓶盖易霉烂。

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.

白酒贮存的环境温度不宜超过30℃，严禁烟火靠近。容器封口要严密，防止漏酒和“跑度”。

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".

开封的白酒用保鲜膜将瓶口仔细包好，用透明胶带缠，瓶口位置将胶带绷直拉紧，多绕几圈，透明胶带有个特性

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

时间越长自身缠的越紧，一定别忘了留出一段胶带头，要不拆时就难了。但是这种做法防“跑酒”效果比封蜡稍差。

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.

没开封的也较好在零摄氏度情况下保存，不过酒精有挥发性，时间长了还是会跑掉不少，商品酒包装不适宜长时间存放。你可以用蜡把瓶口封住，就可以保存很长时间了

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
