The reason why the old wine is valuable is that the long-term storage makes the harmful substances in the wine, such as methanol and formaldehyde, exhausted through volatilization and chemical changes. During this period, there is a process of continuous fermentation and chemical changes. The degree of the wine will be slightly reduced and the taste will be lighter, but the sauce flavor is more sufficient. To continue this process, several conditions need to be met:
1、 Containers need materials such as ceramic pots or porcelain pots with dense structure. These materials are dense and leak free, but they have slight pores, and small molecules can penetrate. Purple sand and other holes are slightly larger, which is easy to leak wine; If glass is used, the harmful substances of small molecules will not come out again.
2、 Appropriate temperature is needed to maintain the activity of microorganisms in wine. If you are drunk above the freezing point in winter, you must not be exposed to the sun in summer. 3-23 degrees is appropriate.
3、 Dry. The wet environment will not only block the pores on the pottery altar, but also make the water penetrate back into the altar. Over time, the wine will be wasted.
4、 Keep away from light. Direct sunlight has a bactericidal effect. Ultraviolet light will kill the active ingredients in the wine and make it unable to continue fermentation.
