-“A cork isn’t useful unless you have a place to put it.” –
Different kinds of closures of wine bottles
Wine bottles have different closures. Corks made of natural cork, imitation corks made out of of plastics, screwcaps, glass / plastic caps. What is the best way to seal a bottle of wine? In fact that’s an easy question. They are all made to seal a winebottle. And if the cap closes properly it is a good cap, isn’t it?
Choice of the winemaker
It depends on the winemaker which one he chooses. Cork is the most expensive choice for the winemaker. This is a natural product of which the price depends on its scarcity.
There is only a limited number of countries where cork oaks grow. In addition, cork can only be harvested once every 9 years. A vintner will therefore only choose cork if he is convinced that this is a good choice for his wines.
One of the characteristics of cork is that it can breathe. Only sealed with a cork wine the bottle can develop. Of course, it has to be a wine that was intended to mature on the bottle. Sometimes cork is chosen for marketing purposes. Customers often think that there always should be a proper natural cork on a wine bottle.
Look at it differently
You can also look at it differently. If there is a screwcap or a plastic cork on the bottle, then this is either a simple (read: cheap, unpretentious) wine or a wine that is intended to drink young (between 1-2 years after purchase). A cork is not necessary at all for these types of wines.
There have been experiments developing a screwcap that also has the ability to breathe. But the real breakthrough is not there yet.
