Does the lack of an oak stopper affect the quality of the wine?

Yes, it is best to plug it with a wooden stopper, because the cork has the characteristics of softness and elasticity, it has many fine pores, when the bottleneck is sealed with it, the cork expands up after contact with the wine, plugging the gap of the bottleneck and preventing the wine from leaking; At the same time, the wine can also be exposed to a small amount of air through the pores of the cork itself, for the purpose of breathing and development, and continues to complete its maturation process after bottling. In addition, the ingredients of the cork are soaked into the wine, which also adds to the structure of the wine.

In fact, it is not uncommon for an oak stopper to get moldy. Most often, the mould on the cork comes from the humid environment of the cellar. Generally speaking, a musty cork does not mean that the wine has gone bad, because wines (especially fine wines) are often stored in large underground cellars, which are a great contrast to the tall wines that many consumers have in their image of tall wines, many of which can be said to be completely covered in mold and rot due to mold growth.

The wines are aged in the cellar for a period of time ranging from a few months to several years, usually between 10 and 15 degrees Celsius, and humidity is even more important: if the cork breaks due to drying, oxygen enters the wine and comes into direct contact with the wine. Wine comes into contact with a large amount of oxygen, which causes oxidation of the wine and the flavor of the wine dissipates prematurely.

Therefore, the humidity of most wine cellars will be maintained at more than 50%, and between 50% and 70% is the ideal humidity environment, so that the wine can be stored for a long time and aged slowly, allowing the wine to fully develop its flavors. In such a relatively high humidity environment, the entire bottle, including the top of the cork, will become moldy, or even completely covered by mold rot.

The winery wipes the bottle clean of mould before wrapping the wine**, but due to the uneven surface of the cork, a small amount of mould remains on the top of the cork. Luckily, mould usually can't penetrate stoppers up to a few centimeters long, so while mildew is not aesthetically pleasing, it has little effect on the quality of the wine.

In fact, the presence of mould on the stopper indicates that the wine has been aged in the cellar for a long time (e.g. Rioja, Spain's highest grade of Gran Reserva, which needs to be aged for 3 years after bottling, and the likelihood of mold on the stopper is much greater than that of lower-grade, shorter-aged Crianza wines), while wines that can be aged for longer periods tend to have a more robust structure and complexity, as well as higher quality. So, as strange as it may sound, mold on a stopper can be one of the hallmarks of a high-quality wine.

It will affect that without corks, the wine will not react slowly, and the wine will not be so mellow.

I think it will affect the quality of the wine, because using an oak stopper preserves the flavor of the wine.

I don't think it will affect you, as long as the plug is sealed well enough.

This will greatly affect the quality of the wine, and the taste will be much different from the mellow aroma of the wine.

The use of oak corks in red wine will affect the texture of the wine and make it less mellow.

I think it will still have a big impact on the precision machining.

Of course, there will be an effect, because this seal is not good, and it will react with the components in the air.

Yes, after all, a good red wine is even an oak stopper, and the aroma of the material must be considered.

Well, it will definitely have an impact, and the final taste will be different, and the mellow aroma of the wine will be gone.

I don't think it will affect it, because the cork is just to make it look better.

I think it will, after all, it will have a great impact on the taste of the sake.

High-end red wines are available with rubber stoppers and wooden stoppers.

What is the difference between cork and rubber cork?

The difference between a wooden cork and a rubber cork red wine is the tightness. The use of corks in red wine can pass through part of the air, so that the red wine in the bottle can react with oxygen and continue to grow; The rubber stopper is directly isolated from the air, which is more sealed, and the red wine cannot continue to grow, so it is suitable for drinking as soon as possible.

What are the types of wine stoppers?

Wine stoppers can be divided into natural stoppers, synthetic stoppers, and polymeric stoppers. Natural stoppers are natural cork stoppers that are also graded differently depending on their elasticity and appearance. The advantage of using a natural stopper is that the stopper has good elasticity, strong airtightness, and produces an oak aroma through contact with the wine.

The material used for the synthetic plug is also oak bark, but not the whole, but the crumbs are processed and pressed and glued together, relatively speaking, ** is much worse than the natural one, the hardness is relatively large, and the elasticity is not as good as the natural one. There is also a 1+1 type in this category, that is, the two ends are natural and the middle is synthetic.

The polymeric plug is a polymer polymeric stopper, which belongs to the synthetic and is a new type of bottle sealing. It is said that it can achieve or even better airtightness than natural cork, but it still needs to be verified, and at the same time, it also lacks some oak aroma. Therefore, to sum up, I personally think that it is better to be natural.

In addition, there are also metal screw caps to seal them. It is more popular in Australia, but it has not yet appeared in China.

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.

The cork of red wine has a whole cork and a broken cork, generally the quality of the whole cork is relatively high, and there is a screw iron cap, most of this wine is the wine of the New World, suitable for drinking directly from the bottle, not suitable for aging, and has nothing to do with the quality.
