Why Screw Caps are the Preferred Choice for Wine Quality

For many wine lovers, the mystique of the corks is still quite powerful. Many associate corked wine with premium quality and top brands. But the situation is changing rapidly, partly due to the growing consumer awareness on the phenomenon of cork tainting, which interferes with the taste and the odor of the wine, giving it a musty smell. In the recent years, you are more likely to find wine bottles with a wine screw cap rather than the good old cork. Innovation in wine packaging, along with the adoption of screw caps by some of the top wine producers in Australia and the world has convinced consumers that these stoppering devices are just as good or even better than corks.

The wine screw cap is no longer associated with cheap wines. In many premium wine selections that are currently available in stores, they have replaced corks as the preferred wine bottle stoppering option. The world’s best wineries now adopt the screw caps and they are slowly becoming an industry standard when it comes to wine closures.

In the wine industry, there are three main options of sealing wine bottles. These include the following:

·         The use of natural corks

·         The use of synthetic corks

·         The use of wine screw caps

Screw caps are increasingly gaining a foothold in the wine industry due to a number of advantages that they offer wine producers. The most obvious advantage is that the materials used in screw caps are generally neutral. Screw caps will not impart any flavor on the wine as they are 100% inert. However long you store you wine, you do not have to worry about any form of tainting of your wine. This is in stark contrast to corks which can impart lots of flavors on the wine which in the end will ruin the quality of the wine.

In fact, one of the central reasons why many vintners are increasingly embracing  screw caps is due to the now infamous cork issues such as the “cork tainting” where the wine is contaminated by trichloroanisole or TCA. This chemical is created when the mold on the cork interacts with the chemicals which have been used in the sterilization of the cork. If the wine has been TCA-affected, it will be characterized by musty or “earthy” odors along with flavors which are not so pleasant. Cork-tainting is so commonplace that it affects up to 10% of  cork-sealed wines. To illustrate this more clearly, one bottle in every case is generally affected by cork-tainting and this can spoil your reputation for quality with your end users.

Wine screw caps are also advantageous in the way they provide 100% impermeable seals for your wines bottles. When you purchase good quality screw caps which are also properly applied, the stopper will form an air tight seal which prevents the diffusion of oxygen into the sealed wine bottle. This will practically prevent the oxidation and the spoilage of the wine. Natural and synthetic corks cannot guarantee such a high degree of reliability in preventing oxygen from getting into the wine bottle.

Screw caps are also increasingly inspiring consumer trust. Consumers feel 100% confident that the wine is safe and in premium condition in spite of the fact that it may not look as “classic” or “sexy”. For the vintner, using wine screw caps guarantees that there will be less variation in the quality of the wines and you can look forward to uniformity of the wine during the cellaring or when it is ageing. The last advantage is that the screw caps are quite user-friendly and you can, therefore, afford to open them without much fuss.
