What's the material for the red wine lid?
According to the law, the bark can only be harvested for the first time until the tree age reaches 25 years. The harvested oak is very irregular in size and density, so it is not suitable for making wine corks. Usually these oak trees are made into floors or good insulating materials. It was not until 9 years later, it can be harvested again on the bark, but the harvest oak quality still can not meet the requirements of cork, poor quality for the production of carpet, ceiling, auto parts and other products of sole. Until the third harvest, that is, when the tree age reached 52 years, the size, size and density of the tree can make it a suitable wine stopper material. In oak life, there are usually 13-18 useful harvests.
The cork is made of the bark of this oak. The bark is a protective layer of trees that is transported to the entire tree through the bark, so the average tree dies when it loses its bark. The cork is made of the bark of oak, which is because the soft oak has two layers of bark. The bark of the inner layer is vital and is the basis for the growth of new bark every year. As the old bark grows and dies, the new bark continues to take on the task of growth. Therefore, the dead bark of the outer layer can be stripped without hurting the trees, but in this process, be careful not to penetrate the vital inner bark.
Quercus suber is a botanical name for green oak, which is quite different from the oak used in oak barrels during winemaking. Not only does this oak need a lot of sunshine, but it also requires a perfect combination of low rainfall and slightly higher humidity. Its bark quality and thickness vary greatly depending on the specific environmental conditions at which it is grown. This oak grows only in certain Mediterranean regions, such as Portugal, Spain, North Africa, etc., and corks play a decisive role in the economies of these areas.
