In the consciousness of Most people in , white wine has no shelf life, not only white wine, but also red wine. After all, who hasn't heard of the 1982-year-old Lafite that can still be sold at a sky-high price?
According to relevant regulations in my country, alcohol products with alcohol content higher than 10 can be exempted from the shelf life, so in white wine, we can almost only see the production date .
This is because bacteria are difficult to survive in alcohol solutions above 10%, and there is no situation where bacterial reproduction causes deterioration under sealing conditions. What's more, the degree of most white wines in my country is basically above 40 degrees.
From this point of view, liquor does not have a shelf life of , but this does not mean that liquor can be stored at will.
We often hear the saying " liquor becomes more fragrant the more it gets, ". It means that after a few years of storage of liquor, the taste and aroma will be much better than when it was first left factory ( is only pure grain wine). . During this period, it has been called " oral " by the industry.
But it is worth noting that not all liquors are suitable for long-term storage. Good things like "10 Years of Blossom Blue and White " and "10 Years of Jianzhuang Saipu 5 " will never come true. Many liquors can no longer be stored for 10 years.
If you have the idea of storing wine, it is recommended to understand these first and then start.
·The necessary conditions for liquor to be suitable for long-term storage
1. Whether the degree is above 50 degrees
Whether liquor is suitable for long-term storage is closely related to whether it reacts when it is aged esterification reaction , or hydrolysis reaction , and this depends on the alcohol content of in the wine body .
High-altitude wine has higher alcohol content . Long-term placement will cause an esterification reaction, which can convert the low-boiling aroma in the wine body into an elegant aroma, and can also make the wine body more silky and round, and drink more harmoniously;
However, low-alcohol wine has higher water content , which is more prone to hydrolysis reactions, which will cause the wine body to become sour, and will also make the wine body thin, and will also produce " water flavor ", which is not suitable for long-term storage, and it is best to drink it within 5 years.
2. Using solid brewing process
The wine that adopts solid brewing process has a rich fragrance component . After long-term storage, various fragrance substances will produce various changes and arrangements and combinations, and will stabilize. The final appearance is that the wine becomes more fragrant as it ages.
Among all kinds of liquors, the most suitable wine for long-term storage is sauce wine , especially the sauce wine with good basic wine quality. Even if it is stored for more than 20 years or even more than 30 years, the aging taste will make the taste better.
This is because the flavor substances contained in the sauce wine are richer than other flavors. For example, pyrazine, furan high boiling point substances are conducive to the formation of colloidal solution . It will be tighter for a long time to store the group, so the taste will be rounder. The rich aromatic substances in
sauce wine are inseparable from its solid brewing process. Let’s take Mutai Houdao Wine as an example.
It uses the 12987 process, which is the traditional solid fermentation process of sauce wine, and the brewing time is as long as 1 years . Such a process requires fermentation in the open environment, so that more microorganisms in the air can be included.
Under the influence of complex and diverse microorganisms, Mutai Houtao Wine can have more than 1400 fragrant substances . These fragrant substances will continue to undergo esterification and oxidation reactions during placement, so that the wine body will eventually have a full and round taste.
will be placed for 5 years before it can be mixed by Moutai old director Li Xingfa disciple Feng Xiaoning teacher. That is to say, after leaving the factory, it will be 6-year-old wine .
And after a long period of placement, the harmful substance in the wine body has also been greatly evaporated, which can minimize the damage caused by drinking as much as possible.
Of course, it is not only sauce wine that is suitable for long-term storage. In fact, wines that contain a lot of fragrance substances are suitable for long-term storage. In addition to sauce wine, there are also Dongxiang liquor and sesame liquor .
3. Good quality and basic wine
. You should choose a wine with a good body foundation itself. Because of the disadvantages of poor quality wine, after a long period of storage, it is likely to be enlarged, such as malignant , etc.
If you want to store wine for a long time, the above 3 points are necessary. Of course, choosing good wine alone is not enough. You also need to pay special attention to the storage environment. It is even better to be able to achieve constant temperature and humidity in an environment that is protected from light, ventilated, and dry !
