Natural Cork Stoppers
Not all cork is created equal. And not every manufacturer treats it the same way.
Our natural cork stoppers begin with the selection of the finest raw material and end with an individual analysis using our VOCUS Cork Analyzer, which detects TCA in less than two seconds—even at concentrations below the human sensory threshold.
More than twelve months of natural maturation in plank form, precision cutting, ozone washing, machine-vision sorting, and surface treatment. Eight quality grades, each designed for the wine it will protect.
Because a wine crafted to age for twenty years deserves a closure made with the same level of care.
Why Choose Our Natural Cork Stoppers?
Controlled Micro-Oxygenation
Natural cork allows a slow, controlled exchange of oxygen between the closure and the wine, with an OTR (Oxygen Transmission Rate) ideally suited to supporting balanced evolution during bottle aging. This process works in harmony with the natural development of great wines, enhancing their balance and elegance over time.
Sensory Reliability
Our individual analysis using VOCUS Cork Analyzer, combined with machine-vision sorting, ensures that every stopper meets the same performance standard—not just statistically, but bottle by bottle.
Twelve Months of Stabilization
We never rush the raw material. Cork planks rest for more than twelve months before processing, allowing their moisture content and internal structure to stabilize naturally. This provides the foundation for consistent, reliable performance in every natural cork stopper.
100% Spanish Origin
Our cork comes from responsibly managed cork oak forests in Spain. With raw materials sourced entirely within the country, we build on Spain’s long-standing excellence in cork production while ensuring traceability and sustainability from origin to finished closure.
Frequently Asked Questions
1. What TCA protection do Parramon Exportap natural cork stoppers offer?
Our natural cork stoppers undergo the ZERO Protocol, a rigorous quality-control process that uses mass spectrometry technology (VOCUS). We analyze each stopper individually to ensure undetectable releasable TCA levels (below 0.5 ng/L). This allows us to provide the highest level of sensory protection while meeting the most demanding technical standards—all without compromising the natural character and prestige of a single-piece natural cork stopper.
2. Why choose a natural cork stopper over a microgranulated or technical closure?
While technical closures offer a high degree of standardization, natural cork remains unmatched for wines intended for long-term aging. Its unique cellular structure enables a precise, consistent, and natural level of micro-oxygenation (OTR) over the years.
It is the only closure that actively supports the maturation and development of great wines in bottle, while also delivering the premium perception that consumers associate with the highest levels of wine quality.
3. Where does the cork used by Parramon Exportap come from?
We work exclusively with locally sourced raw materials. Our cork is sustainably harvested from Spanish forests while preserving the Mediterranean ecosystem.
By controlling the process from harvesting in the forest through processing at our facilities—founded in 1956—we ensure full traceability and minimize our environmental impact.
4. What customization and branding options do you offer wineries?
We understand that the cork stopper is the consumer’s first physical interaction with the wine. That is why we offer state-of-the-art laser customization and branding for both the body and ends of the stopper.
5. What sets Parramon Exportap apart from large multinational manufacturers?
Our true difference lies in personalized service and specialization. We work closely with wineries to create premium cork stoppers that serve as the finishing touch for their finest vintages.
By focusing on uncompromising quality, we provide responsive service, close technical support, and an exceptional level of attention to detail in every finish. The result is a stopper that is more than a closure—it is a piece that expresses and elevates the excellence of your brand.
6. Is cork a sustainable material?
Cork is one of the most sustainable materials used in the packaging industry. Cork oak trees are not cut down to harvest cork. Instead, the bark is carefully removed by hand, allowing the tree to regenerate it naturally.
After harvesting, the tree can absorb up to five times more CO₂ than before the bark was removed, helping make the carbon balance of cork carbon-negative. In addition, cork stoppers are 100% biodegradable at the end of their useful life.
At Parramon Exportap, all our raw material comes from certified cork oak forests, with complete traceability from the forest to the bottling line.
