Most wine bottles are made of oak plugs. Why?

There are several reasons why wine bottles are stuffed with oak.

First, oak itself has certain anti-corrosion characteristics. After disinfection, heating and other treatments, bacteria can be avoided and will not be corroded by alcohol in wine. In addition, its cost is low, which is only time-consuming when processing and making, but for many producers, it is completely within the tolerance range.

Second, oak has very good flexibility. Oak is pressed into the bottle, which can be better sealed and easier to open. If the oak stopper is not damaged, it can be stuffed into the unfinished wine bottle again.

Third, increase the process of oxidation. Different from other wines, wine is fermented from grapes, and it can be fermented better by adding appropriate oxygen. After the project is made, there will be some slight gaps, which is also the reason why the oak plug has certain elasticity. These gaps can let some air into the bottle, so the longer the wine, the more mellow it becomes because of the oak stopper.

Fourth, it is easy to pull out. Because the oak stopper is very strong, it will not fall apart when pulled out, which has advantages over other materials. Of course, it does not rule out that some shoddy oak stoppers are often broken before they are pulled out, or even the cork is directly thrown into the wine, so there are both good and bad aspects in this respect.

Fifth, relatively speaking, wine has a stronger aftereffect, so you won't feel drunk after drinking it, because the degree is usually not high, but the degree and purity of wine preserved with oak stoppers are often higher than what is written on the bottle, so you must stop drinking it, otherwise you may not feel it at that time and get drunk afterwards.

Sixth, in addition to wine, some fruit wines with oxidation function also need to be stuffed with oak to achieve the same effect.
