Before plastic came into existence, and when metal limited usages in society, bottles for all sorts of drinks were made of glass and sealed with cork. Over time, thousands and hundreds of stoppers and bottle closures were invented and implemented. However, only a few have survived from among those thousands, and some more were made functional. Even though wine bottles are still made with glass, there are 5 essential types of bottle stoppers are still in use. The importance of stoppers and closures are generally undermined. In fact, they play a crucial role in revealing some information about the content of the bottle that it is protecting. A stopper can reveal the age of the wine inside, and also the quality. Also, Different stoppers are used for different drinks, For example, the closure that is used for a bottle of soda is different from one that contains beer, etc.
Natural Cork For Conventional Bottles: This is, and always has been, the most common type of stopper that is used for any type of bottle. Even now, with contemporary and fancy techniques for plugging up bottles, cork remains the most favored. It is made from the wood inside a cork tree, which is firm, but slightly flexible. This allows the cork to keep the contents of a bottle completely sealed, while at the same time, allowing the wine to come in contact with the air because of its porous nature.
Aluminium Screw Caps: These are another favored category of bottle stoppers that are used to close wine and other bottles. They are made of aluminium, and keep the contents of the bottle completely airtight. There is no amount of porosity, which is beneficial, because no matter how old the wine is, the original taste, the aromas and the natural flavor remains unchanged.
Glass Stoppers: Glass wine bottle closures, or Vinolok, look very elegant and have an O-ring similar to the one that was used earlier to put a stopper on medicinal jars, etc. Glass is another non-porous element that does not allow any amount of air to come into contact with the contents. Also, because it is glass, there is not even the slightest change in taste, which might occur when you are using wood or aluminium.
Zork: This is a plug-like stopper which makes a ‘pop’ sound when it is taken off a bottle. It is very popular in states like Australia and New Zealand. Zork stoppers are put in champagne bottles, and still and sparkling wine alike.
New Synthetic Corks: This is a relatively new invention, which makes use of corks that are made of synthetic material such as petroleum-based plastic. Even more contemporary manufacturers have come up with synthetic cork that is made with sugar canes. The benefits of such stoppers is that they act and function exactly like corks. They allow the right amount of breathability, helping the wine to age in a finer manner. However, when you use synthetic corks, you can avoid the cork-stains and the slight woody taste that may get imbibed into the wine when exposed constantly to the cork.
