Why is cork only for red wine, and why is cork for red wine but not for white wine?

There is no proof that it is not good to seal without corks. Many wineries in New Zealand and Australia use metal screw caps, which completely eliminate air and ensure that the wine is fresh. Therefore, it is not possible to judge the quality of the wine by using a cork.

And that doesn't mean you don't have a single sealed wine, it's not good, because it's a wine that comes in a lot of brands, in a variety of brands.

Generally, the red wine produced by regular manufacturers is sealed with a wooden stopper, which is the tradition of red wine companies.

This is a different brewing method, the red wine is corked, so that the red wine in the bottle can be fermented a second time, and it can also be breathed through the cork. The alcohol concentration of liquor is relatively high, and if it is corked, it may volatilize into the air.

This is because the cork is soft and elastic, which can tighten the gap between the neck of the bottle and prevent the wine from leaking. The cork also has many tiny pores, which allow a small amount of air to enter the bottle, allowing the red wine inside to continue to develop and mature.

The liquor must be sealed, otherwise the alcohol will evaporate.

Generally, red wine is mostly corked, and white wine is mostly screwed cap, for the following reasons:

1. There are subtle gaps and pores between the corks, which have a channel for exchange with the outside air, which is convenient for red wine to breathe.

2. The cork itself has a woody aroma, and the aroma of the cork can be transmitted to the red wine during storage.

3. Liquor is volatile, and the phenomenon of running wine will occur with wooden stoppers, which will affect the quality and taste of the product.

4. There are many counterfeits in liquor, and the bottle cap must have an important anti-counterfeiting and anti-theft function, which is easier to achieve on the aluminum cap.

Red wine itself is a low-alcohol fruit wine made from grapes. It needs to be stored for a period of time for fermentation and maturation to get a better taste. And this process is inseparable from the participation of oxygen, and the amount of oxygen must be controlled and slowly infiltrated.

If there is too much oxygen, it will acidify and the taste will deteriorate. Cork stoppers are perfect for this purpose. Baijiu is a distilled spirit, the main ingredient is alcohol, which is very volatile, and the cork will let the "liquor" volatilize, which will affect the degree and taste for a long time.

In addition, although liquor also needs oxygen to mature, the demand for oxygen is very low, and it needs more sealing, so most liquor is sealed with screw caps.

A red wine without a cork may be a good wine, because the presence or absence of a cork does not determine the quality of the wine. In addition to the cork sealing method, most red wines will also use the screw cap sealing method, which is lower than the cork sealing method.

Red wine without corks may be good wine, because whether red wine has corks or not does not determine the quality of red wine, and the current way of sealing red wine is not only corked and sealed, there are many red wines that use screw caps to seal red wine.

Corks are the original sealing method of red wine, and the reason why corks were originally used to seal them was because the cork expands when it comes into contact with the wine, which can fill the gaps between the bottlenecks and prevent the wine from leaking. In addition, the cork has a certain oxygen permeability, which will be more conducive to the fermentation and maturation of red wine.

However, the disadvantage of the cork is that the wooden cork is easy to break, and if the cork is too dry or too damp, the cork is easily damaged, and the quality of the red wine will also be affected. And this kind of wine stopper is relatively expensive and costly, so the sealing method of screw cap was born.

As we all know, red wine is a common wine in life, and many consumers will find that almost all red wine sold in the market is sealed with cork. So why cork is used in red wine?

1. The use of cork stoppers can ensure the tightness of the red wine, suitable for the quiet place of the red wine, which also has a certain degree of air permeability, and remember to maintain a certain amount of breathing during the fermentation process of the red wine, so as not to affect the taste of the wine inside.

2. Red wine is generally placed flat, so that the red wine will soak through the cork, the purpose of which is to prevent the wine from being contaminated.

3. A good cork can make the stored red wine not deteriorate, and at the same time, it will not rust, so that your wine will not taste bad.

That's it for a description of why cork is used in red wines.

1. Pure natural cork, natural cork is generally made of selected cork, solid cylindrical cork, this type of cork is generally tightly sealed, so that the wine is not easy to oxidize too quickly, so that the wine is preserved for a longer time, in addition, because the natural cork is generally made of whole wood, and elastic, with small holes and not easy to permeable, its micro-permeability can not only ensure the normal breathing of wine, but also meet the needs of long-term storage of wine, this kind of cork is generally used for high-grade red wine;

2. Filling plug, filling plug is slightly inferior to natural cork, due to too many pores of natural cork, it may lead to red wine seepage, so the special cork powder and binder mixture will fill the holes and defects with larger diameter on the surface to ensure that this kind of cork can be used.

3. Composite cork, natural cork stoppers will form small pieces and small wooden strips in the production process, after waste utilization, the remaining natural cork strips are combined with cork particles and adhesives, at a certain temperature and pressure, through extrusion processing, this kind of cork is called composite cork, which is generally suitable for ordinary red wine.

Made from quercus cork, "quercus cork" is the botanical name for a slow-growing, year-round evergreen oak that grows only in certain western Mediterranean regions. The tree requires a lot of sunlight, a perfect combination of low rainfall and slightly higher humidity, and its bark quality and thickness vary depending on the specific environmental conditions of the place where it is grown.

Known as the "patron saint" of wine, cork stoppers have long been considered the ideal wine stopper. It has to be moderately dense and hard, flexible and elastic, permeable and viscous, and once bottled, the only way for the wine to come into contact with the outside world is guarded by cork.
