How long is the storage time of liquor, and how can liquor be stored for a long time?

After a long period of storage, the quality of the liquor will become warm and mellow. Therefore, some people believe that the older the liquor, the better. Actually, not necessarily.

Although liquor has no expiration date, during the storage of liquor, the alcohols in the liquor will react with organic acids to produce a variety of esters, and each ester has a variety of special aromas. Because the esterification reaction in wine is quite slow, high-quality wine generally needs to be stored for three or four years, or even a little longer. However, when the esterification reaction reaches a certain level, it will tend to be equilibrium and stop state, and if it continues to be stored, the alcohol content will be reduced, the wine flavor will become weaker, and the volatilization loss will also increase.

In particular, some mid-range and low-grade liquors are added with flavoring agents during the blending process, and this kind of liquor cannot be stored for a long time. Otherwise, the wine will become bitter and greasy. Therefore, there is also a proper amount of time for the storage of liquor, and it is not better to get older.

Liquor is volatile, leaking, and overflowing when the temperature rises. Therefore, the following points must be paid attention to when retail and using bulk liquor:

Strict lid When the delivery is suspended, the lid of the wine container should be covered and sealed tightly to prevent volatilization and reduce the wind consumption of the wine.

Don't be too full The container should not be too full to avoid spilling the wine as the temperature rises. It is also necessary to check the container of wine frequently, and if leakage is found, take measures to deal with it in time.

Reduced wastage Do not sell wine too far from the container and use a wine tray to catch it. After the tools for selling wine are used up, they should be put back into the tank in time to keep the tools moist and reduce the skin staining of the wine. With the continuous development of science and technology, mechanized and automated wine storage and sales tools will increase day by day, and it is necessary to learn and master their use well.

Stirring properly Baijiu is a mixture of alcohol and water, and the two are infinitely dissolved. However, due to the different specific gravity, during the storage process, the alcohol content of the upper layer is high, and the alcohol content of the lower layer is low; If it is stored for a long time, the lid is not tightly sealed, and the taste of the upper layer of the wine will be weak. In order to ensure the consistency of the wine and taste, it is necessary to use a wooden rake, stir properly, and hook up and down before taking zero.

Is it true that the longer the liquor, the better? After reading the long insight, it's not too late to know.

It is better to store liquor in glass, stainless steel containers, and at a relatively constant temperature. Pottery, porcelain, wood, bamboo and other containers are suitable for aging wine under certain conditions and for a certain period of time, because it is volatile when stored in wine.

Supplement: The standard definition of liquor is: distilled liquor made by cooking, saccharification, fermentation and distillation with grain as the main raw material, large koji, small koji or bran koji and liquor mother as saccharification starter agent.

It is also known as soju, old white dry, burning knives, etc. The wine is colorless (or yellowish) and transparent, the smell is aromatic and pure, the entrance is sweet and refreshing, the alcohol content is high, and after storage and aging, it has a compound aroma with esters as the main body. It is a variety of liquors made from koji and liquor mother as saccharification starter cultures, and using starchy (sugar) raw materials through cooking, saccharification, fermentation, distillation, aging and blending.

Strictly speaking, a blended liquor made from a mixture of edible alcohol and edible spices cannot be regarded as liquor, but should be called a beverage containing alcohol.

Baijiu is a kind of distilled liquor unique to China, which is one of the world's six major distilled spirits (brandy, whiskey, vodka, gin, rum, and spirit), which is made of starch or sugar raw materials or distilled after fermentation.

Baijiu, also known as soju and baigan, is a traditional Chinese beverage liquor. According to the "Compendium of Materia Medica", it is recorded: "Shochu is not an ancient method, since the founding of the Yuan Dynasty, its method uses strong wine and dregs into the retort (referring to the steamer), steaming on the gas, and using a vessel to carry dripping dew."

It can be concluded from this that the production of liquor in China has a long history. Baijiu is a distilled spirit unique to China. High-quality liquor must have a proper shelf life.

Lu type wine should be stored for at least 3 6 months, and more than one year; The storage period of Fen type liquor is about one year, and Mao type liquor requires storage of more than three years. The alcohol content is generally above 40 degrees, and below 40 degrees is low alcohol alcohol.

Temperature: Constant temperature.

It is better to maintain the temperature of the liquor storage environment at a constant temperature of 12 to 15. Therefore, if the wine storage environment can be maintained at a certain temperature of 5-20 degrees, it is also ideal to maintain a change of 2 degrees.

However, in the summer when there are high temperatures, without any auxiliary conditions, the storage of the liquor should be kept at a constant temperature, such as 26 degrees, within a change of 2 degrees, so as to ensure that the quality of the wine will not be greatly affected for several months. When there is liquor stored at home, the use of air conditioning should indeed be paid attention to.

Placement: Lay flat.

It is better to lay the liquor flat, so that the cork and the liquor can come into contact to maintain its moisture, otherwise if the wine is left straight for too long, the cork will become dry and brittle, and the bottle cannot be completely closed, resulting in oxidation of the wine.

Because the liquor will precipitate after being stored for a long time, the precipitate will gather at the bottom of the bottle when it is placed flat or the bottle mouth is slightly tilted upward; If the mouth of the bottle is tilted downward, the sediment will accumulate at the mouth of the bottle, and it will stick there for a long time, and when the wine is poured, it will be poured into the glass along with the sediment, which will affect the taste of the wine.

Light: Protected from light.

The ultraviolet rays in the light are very damaging to the liquor, and it is also one of the main culprits that accelerates the oxidation process of the liquor, so if you want to store the liquor for a long time, you must put it in a place away from light. In particular, fluorescent lamps tend to reduce the sake's changes and give off a strong and unpleasant taste.

Humidity: Constant humidity.

The influence of humidity mainly acts on cork stoppers, and the humidity is generally more suitable at 60%-70%. If the humidity is too low, the cork will become dry, affecting the sealing effect, allowing more air to come into contact with the wine, accelerating the oxidation of the wine, and causing the quality of the wine to deteriorate. Of course, too high humidity is not good, so a humidity of around 70 is the best environment for wine storage.

It is packed in a clay jar or glass container, sealed and buried in the ground or placed in the basement. Don't use plastic, the liquor basically doesn't care about any conditions, as long as it is sealed well, it's OK!

CCTV liquor brick family said that it is best to wrap it tightly with raw material tape and then wrap it tightly with sealing tape, the wax will smell for a long time, not to mention, go and get my wine first.

Bottled liquor should be selected in a relatively dry, clean, bright and well-ventilated place, and the relative humidity should be around 70%. The humidity is high, and the cap is easy to mold. The ambient temperature of liquor storage should not exceed 30°C.

Fireworks are strictly prohibited. The container should be tightly sealed to prevent leakage and "runaway".

First of all, there are many types of liquor:

Brewed liquor: like beer.

Wine, wine, these.

Bai distilled spirits: liquor, brandy, whiskey.

Pre-blended: Baileys is a type of liquor that is added to other beverage ingredients.

If you want to keep it all year round, the ideal environment for all wines is constant temperature, preferably around 10-15 degrees, constant humidity, dark conditions, these are only available in professional cellars or natural cellar caves.

But the condition of the spirits can be a little worse, for example, it is displayed in the family condition.

It will be stricter for brewed wine, and for ordinary consumers. It can be placed under the bed at home, which is dark and undisturbed.

Put the high liquor into a coarse porcelain jar, seal it with wax, and bury it in the ground to keep it for n years.

Rice liquor can generally be stored for 20 years.

Because rice liquor is pure grain, as long as your storage environment is cool and dry, the storage is well closed, and there is no air leakage, it can generally be stored for 20 years without any problem

And the longer the time, the taste of rice liquor is purer and sweeter, oh [than the heart] [than the heart] [than the heart] [than the heart] to ask the question, glutinous rice liquor, rice liquor, which tastes better?

It must be glutinous rice liquor, which is more mellow than the heart [than the heart] [than the heart] [than the heart], the alcohol content is lower than that of rice liquor, and it is not spicy or spicy in the throat, oh pro [than the heart] The entrance is docile and easy to get on the head [left cover face].

I'm afraid that I don't feel drunk when I'm drunk, this is the power of glutinous rice liquor, I hope my answer can solve your worries, dear, the weather is cold, please pay attention to the cold and keep warm, I wish you a happy life Bixin] [Bixin] [Bixin].

Question: What percentage of rice, glutinous rice, and liquor are produced under normal circumstances? Clinker liquid fermentation answers good quality, generally 70% oh pro [than heart] [than heart] [than heart] [than heart] more than 11 pieces
