When buying red wine, you may have found that some red wine bottles are covered with a layer of plastic wrap, especially those precious red wines. As we all know, cling film is a plastic product used for food preservation. So why do you want to wrap a layer of plastic wrap on the red wine bottle? What does this do?
Should wines be preserved with plastic wrap? This starts with the storage environment of the wine.
What kind of storage environment does wine need?
Constant temperature
The optimum temperature for wine storage is between 10 ° C and 15 ° C and the temperature is kept constant for a long time. Because the thermal expansion and contraction caused by temperature changes will cause the wine to ooze out of the cork, causing the wine to oxidize and contaminate the wine label.
A cold environment will slow the ripening of the wine and require a longer age to reach the drinking period. Excessive temperatures will make the wine taste good, which is not conducive to the ripening of the wine.
2. Constant humidity
The humidity of a typical wine cellar is about 60%-70%. The effect of humidity on wine is mainly reflected in the cork, too humid environment is prone to mold, causing cork pollution and wine label corrosion;
The too dry environment will make the cork lose its elasticity, and it will not completely seal the bottle mouth, which will easily cause the oxidation of the wine and the leakage of the wine.
3. Protect from light
Many food preservation needs to be stored in the dark, and wine is no exception. Light causes the wine to oxidize, giving the wine an unpleasant odour.
Especially those wines that are packed in colorless wine bottles should be stored in the dark to avoid oxidation of the wine.
4. Ventilation
In a humid environment, it is easy to breed mold and produce odor. Therefore, the wine must be kept ventilated during storage to avoid bad odor in the wine.
5. Place
Whether it is a wine rack or a wine cabinet, wines sealed with cork should be placed flat so that the wine and cork are in contact and the cork is kept moist. This will seal the bottle better and avoid oxidation of the wine.
What is the role of wine wrap plastic wrap?
1. Prevent the wine label from being damaged by moisture
Wrap the wine with cling film mainly to protect the wine label. The wine label is a reflection of the wine culture, and the broken wine label is undoubtedly the most troublesome thing. For dealers, the breakage of the wine label is not only bad for the appearance, but also reduces the value of the wine, and it also makes consumers have no understanding of the wine.
The wine storage environment requires 60%-70% humidity. This makes the wine cellar or wine cabinet that is in a humid environment for a long time easy to breed a large number of molds, so that various mildew spots appear on the wine label, and even the moisture is damaged, and the plastic wrap is well protected.
However, it should be noted that in order not to affect the ageing of the wine and the bottle neck and bottleneck, the plastic wrap only needs to tightly wrap the wine label, and the bottle mouth must not be sealed off.
2. Prevent damage to the wine label during transportation
Wines are inevitably subject to various bumps during transportation. The wine label is paper-based. If it is not protected, it will be easy to wear during transportation, and the plastic wrap can protect the wine label from damage.
For many friends who want to get a drink, don't want the wine to suffer a little damage. For many famous wines, there are also many people who like to collect wine labels for commemoration. It is especially important to protect the wine label.
3. Prevent the wine label from being frozen when it is iced
The drinking of wine requires a high temperature. Sparkling wine and liqueur need to be chilled before opening. The plastic wrap can also ensure that the wine label is not frozen, and it can still be clearly presented to the people after chilling.
What is the role of cling film for wine?
In addition to protecting the wine label from the bottle, the cling film has a magical effect, which is to prevent the wine from smelling.
The British Exel Wines company has done experiments, saying that wines that have been contaminated by cork and improper storage can be restored to the original with filter wrap.
But "not every type of cling film is easy to use", but the use of cling film can ensure that the taste of the wine is no longer deteriorated to a certain extent.
However, some experiments have pointed out that although the plastic wrap takes away the odor in the wine, it also takes away the aroma of the wine itself to some extent. Therefore, you can use other methods to remove the odor, try not to use plastic wrap.
