1. Is it true that liquor has no shelf life?
According to the regulations of the General Administration of Quality Supervision, Inspection and Quarantine and the National Standards Committee, the shelf life of drinking wine above 10 can be omitted.
As we all know, the deterioration of food is due to the action of microorganisms. When microorganisms in food are difficult to survive, food is also difficult to deteriorate.
The wine with the temperature above 10 degree has the function of automatic disinfection. Under the condition of proper preservation, it is difficult for microorganisms in wine to grow and reproduce, and the probability of producing harmful substances is small.
Generally, the passing degrees of standard liquor are 28 degrees, 33 degrees, 35 degrees, 38 degrees, 39 degrees, 40 degrees, 43 degrees, 45 degrees, 48 degrees, 50 degrees, 52 degrees, 53 degrees, 56 degrees, 60 degrees and 68 degrees, all of which are above 10 degrees.
Therefore, it is true that liquor has no shelf life.
2. If there is no shelf life, will it really never expire?
In fact, it will still expire, but this period is a "drinking period."
The drinking period of liquor refers to the most suitable drinking period of liquor, and generally speaking, it is the best drinking period of liquor.
Because liquor, as a special food, will continue to undergo esterification reaction during storage, producing aromatic substances, thus making liquor mellow and pleasant.
The esterification reaction will eventually stop, and when the reaction stops, it is the best drinking period of wine. After this optimal drinking period, if it is stored continuously, the alcohol content will gradually decrease, and the taste of liquor will also fade, losing the inherent characteristics of liquor, making people unable to enjoy the best flavor of liquor.
3. Is the drinking period of all liquors the same?
Just like everyone has their own life cycle, each wine has its own "drinking period". There is no fixed answer for how long, and it should be distinguished according to different standards.
Therefore, liquor above 10 degree has no shelf life, and the so-called shelf life is only the "best drinking period". Aged wine means that the longer the wine is stored, the stronger the flavor.
