How to plug a red wine bottle

Sometimes it is impossible to finish drinking red wine in one go, but it would be a pity to pour it out directly. At this time, you can only find a way to plug the mouth of the red wine bottle to ensure that the gas inside will not leak out, and naturally it will not go bad. However, most people don’t know how to plug the mouth of the red wine bottle. The last method is to use a corkscrew. This method is the simplest and most convenient, and can avoid a lot of problems.

Specific method:

During the wine bottling process, the cork is dry and its volume is actually just slightly larger than the bottle mouth, so the machine can easily pressurize it into the bottle. When the cork is in place, the cork begins to expand due to the contact between the cork and the wine in the bottle, which increases its volume and makes it difficult to pull out the seal on the bottle mouth. It is for this reason that wine cannot be stored upright for a long time, because if the cork is stored upright for a long time and becomes dry and cracked like it was in the beginning, it will be easy for air to enter and oxidize the wine.

Since the cork is larger than the bottle mouth, it cannot be inserted by hand after opening. Machines have always been used to push the corks in. Because the corks have a certain degree of elasticity, they can be compressed slightly and then pushed into the bottleneck. It is worth noting that if the wine cork is made of oak, it needs to be soaked in warm water in advance to ensure that the wine cork will not be crushed during operation.

The manual cork tapper is a relatively primitive method of packaging wine. Nowadays, the production method generally adopted is the assembly line, but the principles are basically the same. The corkscrew is generally divided into two parts, with a base at the bottom for the bottle and a small recess at the top for the cork. Then use a lever to lift the bottle up and press the cork down so that it can be driven in just right. The principle is this:

Press the hand lever down, the cork is pushed to the V-shaped mouth, squeezed and thinned, and then the iron rod facing the cork under the hand lever easily pushes the cork into the dry bottle mouth; then put a round plastic paper or aluminum paper on the bottle mouth with the cork inserted, like this (this is already done), then hold the bottom of the bottle and put the bottle mouth into the bottom of a pre-heated iron ring and press it, take it out for about 3 to 5 seconds, and the whole sealing process is completed. If there are some bumps on the iron ring, beautiful prints can be printed on it.
