Have questions? Here are the answers to some common ones!
WHAT TYPES OF WINE WORK WITH UNIQ STOPPERS?
These cork stoppers are ideal for all still wine varieties. Composed of smaller pieces of natural cork, they fit securely in bottlenecks to ensure an effective seal, prolonging wine freshness.
HOW DO UNIQ WINE STOPPERS DIFFER FROM ONE ANOTHER?
The stoppers differ slightly based on the cork particles used. Though each has a unique structure, the visual differences are minimal.
Functionality-wise, the UNIQ2 model absorbs up to 30% moisture, while UNIQ3, UNIQ4, and UNIQ5 models absorb around 25%.
Regarding TCA levels, the UNIQ2 has a content of up to 1.5 ng/L, whereas the UNIQ3, UNIQ4, and UNIQ5 contain up to 0.9 ng/L.
WHAT ARE THE SIZE SPECIFICATIONS FOR UNIQ STOPPERS?
Each UNIQ stopper is manufactured with dimensions of 44 × 24 mm.
ARE THESE STOPPERS SUITABLE FOR SPARKLING WINES?
No, for sparkling wines, we suggest trying the EXPO and VEGA stopper options.
WHAT IS THE TCA LEVEL IN UNIQ STOPPERS?
In the UNIQ2 stopper, TCA levels are up to 1.5 ng/L, while in UNIQ3, UNIQ4, and UNIQ5, the levels are up to 0.9 ng/L. These are considerably lower than typical mass-produced cork stoppers.
CAN YOU EXPLAIN WHAT TCA IS?
TCA, or trichloroanisole, is a compound that may occasionally produce a “corked” flavour in wine. However, it’s still safe to drink even if affected. TCA influences the wine’s scent and taste without compromising its safety.
The less TCA present, the lower the risk of this taint. Choosing stoppers with reduced TCA helps maintain the wine’s pure aroma.
All of our cork stoppers are rigorously tested to minimise TCA levels.
IS NATURAL CORK A SAFE CHOICE FOR CLOSURES?
Yes, natural cork is a secure and non-toxic option for wine stoppers. Sourced naturally from the bark of the cork oak, it releases no harmful substances.
Additionally, cork serves as a protective shield, safeguarding the wine from contaminants such as dust or bacteria, ensuring it stays fresh throughout storage.
HOW DO I STORE WINE WITH THE UNIQ BOTTLE CORK STOPPER?
Consider these easy storage tips:
- Store bottles horizontally – this keeps the cork moist and prevents it from drying, ensuring a lasting seal.
- Keep in a cool, dark place – ideally at a stable temperature of 10-15°C to maintain wine quality.
- Ensure proper humidity – around 70% humidity is best for wine storage.
IS A BOTTLE CORK STOPPER HARDER TO REMOVE?
While cork stoppers may require a bit more effort to remove than synthetic stoppers, it’s a small difference.
Natural cork provides a stronger seal than plastic closures, but with a quality corkscrew, removal is simple and smooth.
DOES NATURAL CORK CHANGE WINE COLOUR?
No, cork doesn’t influence the wine’s colour. Its main function is sealing and controlling airflow. The cork itself doesn’t affect the appearance.
Changes in colour are typically due to natural aging and oxidation processes, not the stopper.
IS NATURAL CORK ALLERGY-FRIENDLY?
Yes, cork is hypoallergenic. Unlike certain synthetic materials, cork doesn’t emit chemicals that might harm health.
For wine, natural cork is especially suitable, as it doesn’t react with or affect the liquid in any way.
Opening a bottle of wine is an experience that should meet your expectations. Natural cork ensures a perfect seal – keeping the wine fresh and free from any undesirable tastes. Plus, its classic look adds elegance to the bottle’s presentation.
#1 CLASSIC, STYLISH DESIGN
Every detail matters when it comes to wine, from the bottle itself to the moment you open it. A cork stopper exudes understated sophistication, without being excessive.
Each cork stopper is one of a kind – nature doesn’t replicate. This gives each bottle a personal touch, something true wine lovers will value.
#2 ALL-NATURAL, WITHOUT SYNTHETICS
Choosing cork is a commitment to nature – no synthetic elements or additives. Cork is directly harvested from the bark of cork oak trees, which live long and provide a sustainable resource. Simply put, cork stoppers are a gift from nature!
No plastics, no artificial materials. Cork represents a sustainable choice without compromising on quality. It’s a small but impactful step towards environmentally friendly practices.
#3 SUPERIOR SEALING
Natural cork is exceptional at preserving the freshness and quality of wine. It seals the bottleneck perfectly, serving as an effective barrier against oxidation.
It protects the flavours and aromas, keeping them intact. Every bottle you open will meet your standards, with no unpleasant surprises.
#4 PLASTIC STOPPERS VERSUS CORK
Comparing synthetic stoppers with natural cork reveals a clear difference, particularly with high-quality still wines.
For example, plastic stoppers can cause quicker loss of freshness. After just a few days, wine flavours may degrade. Natural cork, however, offers an ideal seal, allowing the wine to age gracefully.
Synthetic closures accelerate oxidation, negatively impacting wine quality. Cork’s porous nature allows controlled air exchange, preserving the wine’s character for longer storage.
#5 LOWER TCA RISK
Concerned about unwanted aromas? Rest assured, our cork stoppers have lower TCA levels, keeping the wine’s flavour pure.
This means you can enjoy wine as it’s meant to taste, with no unpleasant surprises. Each bottle remains as expected – nothing hidden in the glass.
#6 AN OLD-WORLD TOUCH
Opening a bottle sealed with a natural cork connects you to a rich heritage. Cork has been trusted by winemakers for centuries to preserve wine at its best.
Each cork stopper tells a story, allowing wine to age as it has for generations. This closure not only seals the bottle but honours a long-standing tradition in winemaking.
