Why there is small holes in the top of wine capsule?
The role of the wine bottle cap, you should not underestimate this inconspicuous small bottle cap, the small hole on it is not only to the role of closure, but also a more important role - to make wine more delicious, let us detail Learn about the role of this humble little hole.
There are small holes in the wine bottle
cap. I believe that people who drink wine regularly find it. But friends who
don’t have much contact with wine may feel strange. Is this bottle of wine
being touched? If you see this picture above, This kind of small hole can be
assured that your wine has not been touched by people, but when it is filled,
the winery "deliberately". Why is there a small hole on the bottle
seal? So what is the role of the small hole in the wine bottle capsule? In
fact, this is not a defect in a bottle of wine. On the contrary, the right quantity
of small holes has the following three positive effects on wine:
1. Exhaust: These small holes can be used for exhausting function when doing capsule shrinking. In the process of mechanical capsule shrinking, if there is no small hole exhaust, there will be air between the bottle cap and the bottle mouth, which makes the wine capsule fall slowly, affecting the production speed of the capsule packing line, and during heat shrinking for polylaminated and PVC capsule, the residual air is trapped in the wine capsule, which affect the appearance of the cap.
2. ventilation: These holes are also the
venting holes of wine when the wine will be stored long time. 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.
3. moisturizing: We all know we need pay attention to the humidity
requirements in addition to light, temperature, placement during storage of
wine. This is because the cork is contractile. If the humidity is too low, the
cork will become very dry and the air tightness will be poor, which may cause a
large amount of air enter into the bottle to accelerate the oxidation of the
wine and affect 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.
4. Not all wine bottle seals have small
holes. The wine bottle sealed with a screw cap has no small holes. Some wine
merchants use a screw cap to preserve the flower and fruit aroma in the wine,
so that the air entering the bottle is particularly small or almost no, which
can inhibit the oxidation process of the wine (the flower and fruit fragrance
will gradually disappear after the bottle is aged). The cover 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. The
presence or absence of a small hole in the bottle seal is more dependent on the
will of the wine producer, because there are small holes in both the low-end
and the high-end wines. Of course, there will be no small holes, we don't have
to worry too much, just remember that the existence of these holes does not
harm the wine.
Some people say that this makes a small
hole in the bottle cap to make a bottle of good wine look unsightly, people
look very awkward, I believe you will not think so after knowing this reason,
it is with these holes to make sure your wines are more delicious, and of
course not all wine bottles have small holes because each wine is with a slightly
different.
