As we all know, most baijiu gets better with age. Baijiu that is 10 or 20 years old has a pleasant aroma and softer taste. So why doesn't baijiu have a shelf life like other food? custom wine boxes why do not generally standard shelf life? Can baijiu never go bad? Wines with a shelf life of less than 18 months will be listed, and those older than that will not be mandatory. There are many things about the expiration date of wine. According to relevant regulations, drinks with alcohol content greater than or equal to 10vol% can be exempted from the shelf life label. Because microorganisms cannot grow and reproduce and produce harmful substances even in a 10% alcohol solution; Liquor alcohol degree is relatively high, and above this degree of alcohol, fungi basically difficult to survive, there will not be deterioration problems, so you can not mark the shelf life. However, if the alcohol level is very low, the microorganisms in the wine are easy to grow and multiply, so that the wine deteriorates and produces sour taste, therefore, low alcohol should not last long. Baijiu generally does not have a shelf life, but this does not mean that the longer the baijiu is stored, the better. After five years of ordinary flavor baijiu, the taste will become weaker and the fragrance will weaken. Maotai-flavor old wine is a good wine, but whether the Luzhou-flavor wine stored for many years is a good wine has not been concluded at present, there is a big dispute; Low alcohol liquor, especially the liquor below 32 alcohol, the longer the time, the more likely to cause the performance change, the longer the time, will lose the inherent characteristics of liquor. In this regard, the country has strict regulations, requiring that the alcohol content of less than 10% drinks, such as the shelf life must be marked.
