In countries like the United Kingdom, approximately 90% of white (and especially young) wines use the Screw Cap closure. This is also the case in New Zealand, South Africa and Chile, where screw caps have been used as closures for their wines for years. In fact, 92% of New Zealand wines are closed in this way, while in Chile and South Africa the figure is 53%. These countries have an established wine culture and excellent production in terms of quality.
The key, we are sure, lies in understanding that the screw cap is compatible with some types of wine and not with others.
Advantages of the screw cap
A bottle closed with a screw cap can contain an excellent young or fruity wine, as well as any other product that does not necessarily require aging in the bottle; in other words, wines meant for near-term consumption. In fact, screw caps have some advantages over other types of closures:
- The aluminum screw cap prevents oxygen from entering the wine, preserving its fruity fragrance.
- The aluminum cap is more versatile for certain decorations.
- It is more convenient and easier to open. For this reason, it is widely used in bars, where speed and by-the-glass consumption are essential.
In conclusion, experts recommend screw caps for certain types of wine and those meant to be consumed in the short term. On the other hand, for wines that require aging or maturation, natural micro-granulated cork remains the ideal choice.
The evolution of the screw cap
We must understand that technology has advanced by leaps and bounds, making it possible today for a screw cap, such as Torrent’s Roscap, to be perfectly adaptable for a high-quality wine.
At Grupo Torrent, we have more than 50 years of experience in manufacturing wine screw caps and aluminum closures. Our Pilfer/Stelcap line ensures the wine remains in perfect condition from the moment it reaches the market until it is consumed.
As manufacturers of screw caps, we also see that the use of this type of closure as an alternative to cork for sealing wine bottles is gaining increasing support in Spain, Portugal, and other European Union countries that until recently were reluctant to use such closure solutions.
At Torrent Closures, we understand the magnitude of the trust placed in us by our clients, and for this reason, safety is paramount in our screw caps. In our commitment to food safety, we have developed solutions ranging from laser-printed numbers on the caps, which are nearly impossible for counterfeiters to replicate, to invisible inks that prove product authenticity—resulting in closures that are extremely difficult to duplicate.
If we look at the advantages aluminum screw caps offer for wine, we see that they fulfill their function even better than traditional cork. The screw cap provides an airtight seal for the container, preventing any contamination or odor, while at the same time preserving the wine’s properties and nuances.
