These stoppers are great for all varieties of still wines. Made from finely granulated cork pieces, they fit snugly in the bottleneck, ensuring an airtight seal to maintain the wine’s freshness for longer periods.
The key difference lies in the size of the cork granules used for each stopper model. While all provide excellent sealing, their texture and structure vary slightly.
Performance-wise, the UNIQ2 stopper absorbs up to 30% moisture, while UNIQ3, UNIQ4, and UNIQ5 models handle up to 25% moisture. This slight variation ensures suitability for different types of still wines.
Regarding TCA content, UNIQ2 contains up to 1.5 ng/L, whereas UNIQ3, UNIQ4, and UNIQ5 offer a lower level of up to 0.9 ng/L, giving wine enthusiasts added confidence in the purity of their wine.
Each stopper measures precisely 44 mm x 24 mm, ensuring a consistent fit across various bottle designs.
No, these stoppers are specifically designed for still wines. For sparkling options, we recommend checking out EXPO or VEGA stoppers, which are tailored for the pressure and carbonation of sparkling wines.
The TCA level varies slightly between models. For instance, UNIQ2 has a maximum TCA content of 1.5 ng/L, while UNIQ3, UNIQ4, and UNIQ5 contain just 0.9 ng/L. These levels are much lower than most conventional corks, ensuring an enhanced tasting experience.
TCA, short for trichloroanisole, is a naturally occurring compound that can cause an unpleasant musty odor or taste, often referred to as a "corked" wine. Thankfully, all UNIQ stoppers undergo rigorous testing to minimize TCA levels, significantly reducing the risk of this happening.
Low TCA levels ensure the wine’s aroma and flavor remain unaltered, allowing the wine’s true character to shine through.
Absolutely! Natural cork is a safe, sustainable, and healthy material. It is harvested from cork oak trees and does not release any harmful chemicals into the wine.
In addition to its safety, cork provides excellent protection by creating a natural barrier against bacteria and contaminants. It helps maintain the purity and freshness of the wine, ensuring an enjoyable experience with every sip.
Proper storage is crucial to ensure the wine maintains its quality. Follow these simple tips:
Removing a natural cork stopper is straightforward with the right tool. Although they create a tighter seal compared to synthetic alternatives, a quality corkscrew makes the process effortless.
No, natural cork has no effect on the color of the wine. Its role is to seal the bottle while permitting minimal airflow, which is crucial for aging.
Changes in wine color are typically due to oxidation or natural aging processes, not the stopper itself.
Yes! Natural cork is hypoallergenic and free from harmful chemicals. It doesn’t release any allergens or interact with the wine, ensuring a safe and enjoyable drinking experience.
Opening a bottle of wine should always deliver the experience you expect. That’s where natural cork truly stands out – it creates a secure seal, helps maintain freshness, and reduces the chance of unwanted flavors. Its refined look is an added touch that beautifully enhances the overall presentation of the bottle.

When selecting a bottle of wine, the details make all the difference – especially when it’s time to uncork it. A natural cork closure represents understated sophistication, offering elegance without excess.
No two corks are ever the same – each one carries its own natural texture and character. This uniqueness adds an individual touch to every bottle. It’s a subtle detail, yet one that true wine lovers will instantly recognize and appreciate.
Choosing natural cork means choosing authenticity – free from synthetic materials. Harvested from the bark of cork oak trees, this renewable resource is nature’s own solution for wine preservation. In fact, cork stoppers quite literally come straight from the tree.
No plastics, no chemical imitations – just pure, natural material designed to protect your wine. It’s a small component with a big impact, reflecting both environmental awareness and a commitment to quality.
Natural cork excels at safeguarding what matters most in wine. It adapts perfectly to the shape of the bottle neck, forming a tight seal that helps control oxidation.
It preserves delicate aromas and flavors, locking them in for longer. Every time you open a bottle, you get exactly what you expect – a consistent, high-quality tasting experience without surprises.
There’s a clear difference between natural cork and lower-cost synthetic closures – especially when it comes to premium still wines.
With plastic-based stoppers, wine tends to lose its freshness faster. Even after a short period, aromas and taste can noticeably decline. Natural cork, by contrast, ensures a reliable seal and supports proper aging conditions. This allows wine to maintain its full character over time.
Synthetic closures may accelerate oxidation, which can negatively impact the wine. Natural cork, thanks to its micro-porous structure, enables controlled breathing. This balance helps protect both flavor and aroma, even during extended storage.
Concerned about unwanted off-flavors? You don’t have to be. Our natural cork stoppers are processed to ensure extremely low TCA levels.
This means you can enjoy your wine exactly as intended – pure, clean, and true to its character. Every bottle remains a reliable choice, free from unpleasant surprises.
Opening a wine sealed with natural cork connects you to a heritage that spans centuries. Winemakers have trusted this method for generations to preserve wine at its best.
Each uncorking is part of that legacy. Natural cork doesn’t just close the bottle – it supports the aging process in the same way it has for hundreds of years, preserving both the wine and the tradition behind it.
