Secrets of wine stoppers

The main function of wine stoppers is reducing the exposure of wine to the air condition to protect its original taste. Besides, there are some interesting facts about those small items that you might not know. Let’s discover with La Badiane.

  1. Corks

Corks or liège are made from  the dead cells of the oak bark. The component inside of the cells is nitrogen and the outside is suberin. Suberin is a waterproof material, so that they prevent the wine from flowing out of the bottom. Thus, the bottle closed with cork is suitable for keeping the wine fermented.

Each Quercus Suber oak must be grown in 25 years or more to provide 70 mm thick bark. 14 years latter, people will peel the first oak bark but it will be discarded because of a rough surface and unusable tannin. Another 12 years later, the regenerated second bark with smooth surface can be used for making wine corks.

  1. Screw Caps

Screw caps are descendants of liège. It was invented by Dan Rylands of Bamsley on August 10, 1889. Until 1926, the consumption of spirits increased thanks to the convenience and low price of metal screw caps.

6 steps to open wine liège

1. Use a knife to cut the wrapped tag in bottle-neck

2. Turn the screw into the cork of the wine bottle. Notice not to turn it out of the center of the cork, otherwise, it will not break apart into smaller parts.

3. Stop when the tip vortex almost inundates. Folding the prongs to leverage the bottleneck.

4. Slowly push the cork up vertically. The force of the leverage will push the button and minimize the risk of breaking cork.

5. Stop when the cock is still in the bottleneck (about half a centimeter). If you withdraw it more strongly, it will create uncomfortable sounds. Additionally, there may be small debris falling inside the bottle.

6. Use your fingers to gently pull out the cork. Use a towel (no cotton) to gently wash the head of bottle. Do not throw the cork away. Reuse it if there’s some wine left after drinking.
