Cork pollution is mainly due to natural substances in oak cork, so we should try to avoid red wine with natural oak cork and choose wine with synthetic cork instead.
This is in fact the expert said that a good red wine should be chosen like this, for example, this French red wine is not perishable.
The wine is sealed with synthetic cork into the wine.
On the one hand, it can avoid pollution and is not easy to deteriorate;
On the other hand, the loose and porous structure of the cork is conducive to softening the wine body.
Since red wine is made from unpeeled grapes, the skins contain a lot of tannins, and the tannins give off a bitter taste, softening the tannins is an extremely important step.
The special structure of the cork transforms the tannin into a sharp flavor.
Therefore, the wine sealed with cork is more mellow and sweet, without bitterness.
