How to preserve liquor for a long time?

Question 1: What liquor can be stored for a long time? Does liquor have a shelf life? Is the liquor as long as possible? After long storage, the quality of liquor will become moist and mellow. So some people think that the older the liquor, the better. Not really. Although liquor has no shelf life, during the storage process of liquor, alcohols in liquor will react with organic acids to generate a variety of esters, all of which have various special aromas. Because the esterification reaction of wine is quite slow, high-quality wine generally needs to be stored for three or four years or even longer. But when the esterification reaction reaches a certain level, it will tend to be balanced and stop. If it continues to be stored, it will reduce the alcohol content, weaken the taste and increase the volatilization loss. Especially at present, some middle-and low-grade liquors are added with flavoring agents in the blending process, and such liquors cannot be stored for a long time. Otherwise, the wine will become bitter and tasteless. Therefore, there is also an appropriate time for liquor storage, not the older the better.

Liquor is volatile, it will leak, and it will overflow when the temperature rises. Therefore, when retailing and using bulk liquor, we must pay attention to the following points:

(1) Cover tightly. When the delivery is suspended, cover and seal the wine container to prevent volatilization and reduce the wind consumption of wine.

⑵ Don't fill the container too full, so as to avoid the overflow of wine caused by the rising temperature. Check wine containers frequently and take timely measures to deal with any leakage.

(3) Reduce losses. When selling wine, don't be too far away from the container, and use the wine tray to receive the wine. The tools for selling wine should be put back into the cylinder in time after use, so as to keep the tools moist and reduce the skin of wine. With the continuous development of science and technology, there will be more and more mechanized and automatic tools for storing and selling wine, so we should learn and master their usage methods well.

(4) Properly stirred wine is a mixture of alcohol and water, which are infinitely soluble. However, due to the different specific gravity, the upper alcohol content is high and the lower alcohol content is low when stored. If it is preserved for a long time and the seal is not tight, the taste of the upper wine will be weak. In order to ensure the consistency of alcohol content and taste, it is necessary to use a wooden rake, stir it properly, and mix it up and down before taking it.

It should be possible to say so, but only if the storage condition should be 1. Sealing and setting. Suitable temperature: 0-30 degrees. Many places in China have excavated 1000-year-old wine kilns, which still contain quite a few ancient wines.

The change of liquor is probably like this: the main component is ethanol, and the percentage of ethanol content is the alcohol content of liquor. In addition to ethanol, there are artificially added spices, medicinal materials, microorganisms remaining in the distillation process, methanol (the blinding thing in fake wine), acetaldehyde (the mellow substance of liquor) and so on. It slowly transforms the ethanol in liquor into acetaldehyde over time in an oxygen-free environment, so there is a saying that "wine is the fragrance of old age". The longer the liquor is stored, the less the ethanol content, the higher the acetaldehyde content and the more fragrant the liquor is, so the longer the liquor is stored under the above conditions, the better.

Question 2: How to store liquor for a long time? "Being" is not the same as aging. For alcohol storage, glass and stainless steel containers should be sealed and the temperature should be relatively constant. Pottery, porcelain, wood, bamboo and other containers are suitable for wine aging under certain conditions and time, because the wine stored in them is volatile.

Question 3: Can all liquor be preserved for a long time? First of all, we must know that liquor facing consumers has a shelf life. If you don't believe it, you can check whether there is a shelf life on the bottle. Generally, there are no special circumstances that have a shelf life. This standard is stipulated by the state. Secondly, we usually hear that "wine is the fragrance of old age" is the wine in the wine cellar.

During the storage process of wine, alcohols in wine will react with organic acids to form a variety of esters, which all have a variety of special aroma. Because the esterification reaction of wine is quite slow, high-quality wine generally needs to be stored for three or four years or even longer. But when the esterification reaction reaches a certain level, it will tend to be balanced and stop. If it continues to be stored, it will reduce the alcohol content, weaken the taste and increase the volatilization loss.

However, it should be no problem to store it for 5 years 10 years ~ ~ Finally, warm reminder: the wine that the landlord likes should be sealed and stored in a dry and constant temperature place (the temperature should be kept at around 1 1 degree).

Question 4: How much liquor is suitable for long-term preservation? Liquor will be hydrolyzed during storage, that is, the acid content is high and the ester content is low, so liquor with low alcohol content is not suitable for long-term storage.

Liquor above 53 degrees is suitable for long-term storage.

Liquor brewed by traditional techniques (alcohol-free blended liquor) is suitable for long-term storage.

Maotai-flavor liquor is more suitable for long-term storage than Luzhou-flavor liquor and Fen-flavor liquor.

Question 5: How can wine be preserved for a long time? There are many ways to preserve wine, and some wines are not suitable for long-term preservation.

Preservation of liquor: the original liquor with good quality should be put into a ceramic container, sealed and protected from light, and stored at low temperature. It should not be opened for ten years, the quality will be greatly improved and the taste will be much better. General finished wine is not suitable for long-term storage, and its trace components will change during storage, so it is best to drink it within three years.

Preservation of red wine: it is no problem to keep it in a low temperature place or in a wine cellar or wine cabinet for several years.

Question 6: What kind of wine can be stored for a long time so that it can be taken out for drinking when it is old? Most people think that the longer liquor is stored, the better. After all, wine smells old. But in fact, low-alcohol wine has no storage value at all. On the contrary, low-alcohol wines have a shelf life. Too long storage time will affect the taste and quality of wine, and even expire. Therefore, if you want to store liquor, it is best to choose puree liquor with a temperature above 50℃, and if you want to store maotai-flavor liquor, don't use Luzhou-flavor liquor. It is suggested that these 10 old wines stored for 20 years must be blended when they are sold. If you don't blend it out after 20 years, it will be awesome. Old wines stored for 5 years are sticky, and the viscosity of wines stored for 20 years is even more awesome. This wine must be blended with new wine, otherwise it can't be drunk.

It is recommended that Maotai Cave store old wine and Anhui Gujing Distillery Luzhou-flavor pure grain original wine. It is most suitable for kiln collection, and many people collect it.

Question 7: What should I do if I want to preserve high-grade liquor for a long time? Dig a cellar and bury it. It is recommended to avoid light, and a place that is not wet will do.

Question 8: The longer the liquor is stored, the better. Liquor has long storage time, mellow and moist taste and pure taste. So some people think that the longer the liquor is stored, the better.

Indeed, liquor stored for a long time is "fragrant, fragrant, fragrant". The reason why the "three flavors" are concentrated is mainly because of the "esterification reaction". The main component of wine is ethanol. In addition, there are more than 10 higher alcohols and more than 20 organic acids. During the storage of liquor, alcohols in liquor will react with organic acids to form a substance called ester, and each ester has its own special flavor. Because the formation of esters is quite slow, it is necessary to store wine for a long time to make it have a rich aroma and mellow taste. However, the chemical reaction between alcohol and organic acids in wine is not endless, but tends to balance to a certain extent, and the formation of esters will stop at this time. In this case, if it continues to be stored, it will not only make the fragrance stronger, but also produce negative reactions, such as yellow color, weak wine taste and reduced quantity.

So the general storage time of liquor should be four or five years or a little longer.

Question 9: How to store liquor for a long time? "Being" is not the same as aging. For alcohol storage, glass and stainless steel containers should be sealed and the temperature should be relatively constant. Pottery, porcelain, wood, bamboo and other containers are suitable for wine aging under certain conditions and time, because the wine stored in them is volatile.
