Which is suitable for red wine, aluminum cap or cork

The sealing form of wine bottle is very much, but wine bottle USES cork sealing more, especially high-grade wine, want to choose the cork that good cork makes more.

France Bordeaux second University wine technology institute, there is a specialized research laboratory cork, in addition to the study of synthetic materials to make simulation cork, but also liquid chromatography, gas chromatography and other analysis of cork components and the impact on the quality of wine aroma.

So why the cork seal?

The reason is cork has soft and the characteristic with stronger flexibility, it has a lot of fine small hole, after sealing bottle neck with it, cork classics and wine liquor contact expand rise, plug tight the gap of bottle neck, prevent wine liquor leakage;

At the same time, the liquor can be exposed to a small amount of air through the micro-hole of the cork itself to achieve the purpose of respiration and development, and continue to complete its maturation process after bottling.

In addition, the cork ingredients soaked into the wine will also increase the structure of the wine.

It is said that before wine was sealed with a cork, there was no special wine bottle stopper.

It is usually done by first plugging the container with some material such as rattan and then sealing it with wax.

That has a lot of drawbacks: in the opening process will inevitably have wax particles and grass cuttings fall into the wine, thus affecting the health of the wine;

Lax sealing leads to serious oxidation of liquor, which affects the quality of liquor;

Liquor leakage is more difficult to avoid, causing a great loss.

The material selection of cork and manufacturing technology are very complex, as the progress of science and technology, now cork is no longer confined to log making, however the method that USES artificial synthesis will make, the cork that makes USES effect and log to make have no difference, be widely used.

Wines made with metal caps are generally very cheap, and good wines are mostly made with corks.

Cork is a natural product made from the bark of an oak tree. It is elastic and restorable and can be completely sealed when compressed into a bottle.

However, when dry, the elasticity decreases due to shrinkage, which is why the wine must be placed horizontally to allow the cork to wet and preserve the wine.

Today, there are also artificially compressed corks made to replace natural corks, but in general, most high-priced wines use natural corks.

Because corks live for about 30 years, they can preserve older wines.

Liquor does not need cork. First, the brewing process and preservation method are not as strict and complicated as wine. Second, it is to save production cost.
