Why use a cork stopper?

Its main function is to preserve the properties of the wine in time and to ensure that it evolves correctly in the bottle. 

The advantages of the cork stopper 

The cork stopper prevents a large amount of oxygen from penetrating, which would damage the wine. Indeed, they play an essential role in the quality of the wine. 

As explained above, the cork stopper has first of all a function of protection. This last one also plays another very important role as for the taste of the wine. Indeed, according to the cork stopper, the gustative characteristics will vary and will impact greatly the aromas of this last one. 

The disadvantages of the cork stopper 

Cork stoppers can also have certain disadvantages. We can notably mention the humidity. Indeed, for it to ensure its protective function, it must be slightly humid. Without this, the wine will lose its aromas and its conservation will be alternated. Moreover, a lack of humidity can dry out the cork excessively. This can cause the cork to break. If this happens, the wine will be altered because of the amount of air that will enter the bottle.  

The different alternatives 

In recent years, the cork stopper is sometimes replaced by synthetic stoppers. These have the same protective function as cork stoppers, preventing the passage of oxygen as well as bacteria and fungi. This alternative also has another important advantage: it does not break despite humidity and it does not produce dust. 

However, the use of synthetic stoppers is still very much in the minority and contested by many in the wine industry. Indeed, the cork stopper remains the best material to preserve the wine and its properties, this is due in particular to its proven effectiveness in the long term.
