I don't know if you have noticed that there are a few holes in the wine cap. What do you do in this? Some people think that this bottle of wine itself has problems, and it has been moved by others. In fact, these holes The effect is very big! Today, let's talk about the magical effect of the small holes in the wine cap.
1. The role of exhaust
These small holes in the wine cap can be used as a hood for exhausting. Because the wine sealed with cork stopper has a link in the process of sealing the bottle - the tin foil cap. However, in the process of high-speed mechanical caps, it is easy to form a gas pressure between the cap and the bottle mouth due to the resistance of the air, so that the production speed of the machine is slow. With these small holes, excess gas can be quickly discharged and the production efficiency can be improved. In addition, in order to prevent the air cap from being sealed in the cap during the cap (tin foil cap) and heating (thermoplastic cap), the wine is not tightly sealed and the residual air is enclosed in the cap. The unevenness of the bottle seal affects the appearance of the cap.
2. Ventilation
In the process of ageing, wine requires a small amount of oxygen to oxidize, so that the wine develops more complex flavors in the bottle. These venting holes are designed to help the wine to have access to the air in a completely sealed condition, thereby interpreting the complex flavor of the wine and extending its life.
3. moisturizing
In addition to paying attention to light, temperature, and placement, wine preservation requires moisture. This is because the cork is contractile. If the humidity is too low, once the cork is dried, the tightness will be greatly reduced, and a large amount of air will enter the bottle, which will affect the quality of the wine. The small holes in the cap help the cork of the wine to come into contact with the moisture in the air, which acts as a moisturizer to prevent the cork from drying out.
4. Do you have a small hole?
In general, wines with screw caps or wax-sealed wines generally do not require such holes. In order to preserve the aroma of flowers and fruits in the wine, the wine with spiral cover and beeswax can prevent the exchange of gas with the outside world, can inhibit the oxidation process of the wine, prevent oxygen from entering the bottle through the bottle cap and cork, which is to a large extent It reduces the possibility of wine being oxidized.
It is also worth noting that not all cork wines have small holes, and the presence or absence of small holes in the wine cap depends entirely on the manufacturer's production requirements, so it is not necessary to entangle the number of small holes or small holes. Just remember that the presence of these holes is not bad for wine.
