In reality, it is almost airtight because some air is able to pass through natural cork , because microscopically there are holes inside the cork structure. This can be beneficial or harmful, depending on the type of wine that is stored. Some wines age better with exposure to air for periods of time, while others stay much better when exposed to the absence of air during storage. Both the type and size of the cork are determined by the type of wine , the amount of pressure contained within the bottle and the diameter of the bottle neck.
Today, there is a wider variety of types of wine corks and bottle stoppers to preserve wine. Some winemakers, especially those who produce great volume, are using screw caps instead of corks. While the type of cork or lack of it somehow affects the taste of wine over time , as well as our perception of taste, it is also critical in protecting wines as they age.
Some types of wine corks are more reliable than others. Natural one-piece corks are ideal for long-term wine aging , as they expand and stay strong for long time periods. Mobile Newsletter banner close. Mobile Newsletter chat close.

Stripping the bark -- A cork oak must be at least 25 years old before its bark can be harvested. Its cork can then be stripped every 8 to 14 years after that for as long as the tree lives. The cork is stripped off during June, July and August using a long-handled hatchet to cut sections out of the bark.
These holes can be used as a venting cap. In the process of mechanical cap, if there is no small hole exhaust, there will be air forming air cushion between the bottle cap and the bottle mouth, which makes the wine cap fall slowly, affecting the production speed of the mechanical assembly line, and in the cap tin foil cap When heated thermoplastic cap , residual air is trapped in the wine cap, affecting the appearance of the cap.
These holes are also venting holes for wine, which can be easily carried out in old age. A small amount of oxygen is good for wine, and these vents are designed to help the wine have access to the air when it is completely sealed.
This slow oxidation not only allows the wine to develop a more complex flavor, but also extends its life. This is because the cork is contractile. If the humidity is too low, the cork will become very dry and the airtightness will be poor, which may cause a large amount of air to enter the bottle to accelerate the oxidation of the wine, affecting the quality of the wine.
The small hole in the bottle seal can maintain a certain humidity of the upper part of the cork and maintain its sealing performance. Not all wine bottles have small holes in the seal The wine is sealed with a screw cap, and there is no small hole in the bottle seal. Some wine merchants use a screw cap to preserve the floral and fruit aroma in the wine.
The air entering the bottle is particularly low or almost absent, which can inhibit the oxidation process of the wine the fruit and fruit will gradually disappear after ageing in the bottle. The screw cap has no ventilation function like a cork, so there is no need to punch holes. However, even wines that are closed with cork stoppers do not have small holes. They also obscure the cork and fill in the bottle, which is important. If the fill is not close to the cork, the wine may be oxidized.
Occasionally, reason triumphs over habit as it seems to be doing now among some young winemakers. We should drink to that.
