NATURAL CORK STOPPERS FOR WINE
Not all cork is the same. And not all cork makers treat it the same.
At Parramon Exportap, our natural cork stoppers begin with raw material carefully selected in the forest and end with an individual analysis using our VOCUS Cork Analyzer — detecting TCA in under two seconds, even at concentrations below the human sensory threshold.
More than twelve months of natural plank seasoning, precision cutting, ozone washing, artificial vision grading, and surface treatment. Eight quality grades, from Flor-Miroir to N3, each matched to the wine it is meant to protect.
Because a wine designed to age for twenty years deserves a closure crafted with the same level of care.
Why Natural Cork, and Why Parramon Exportap?
Controlled Micro-Oxygenation
Natural cork allows a slow, controlled exchange of oxygen between the closure and the wine. This is not a defect — it is the mechanism through which great wines develop complexity over years of bottle ageing. Our closures are engineered to make this process consistent and predictable.
Sensory Reliability
Bottle variation often starts with the closure. Our individual VOCUS Cork Analyzer screening and AI-based visual grading ensure that every cork in a batch performs to the same standard — not just statistically, but bottle by bottle.
Twelve Months of Natural Seasoning
We never rush the raw material. Cork planks rest for more than twelve months before processing, allowing the natural stabilisation of moisture and internal structure. This is the foundation of consistent and reliable performance.
100% Spanish Origin
Our cork comes from responsibly managed cork oak forests in Spain. Sourced exclusively from Spanish raw material, it reflects the country’s long-standing excellence in cork production while ensuring full traceability and a sustainable origin.
Eight Quality Grades for Every Wine
From Flor-Miroir — our highest-grade natural cork, reserved for wines with exceptional ageing potential — to our N grades designed for earlier-drinking wines: the right closure for every wine, with no compromises.

Frequently Asked Questions
1. What guarantee against TCA do Parramon Exportap natural cork stoppers provide?
Our natural cork stoppers undergo the ZERO Protocol, a comprehensive quality-control process based on mass spectrometry technology (VOCUS technology). Each cork is individually analysed to ensure non-detectable levels of releasable TCA (below 0.5 ng/L). This allows us to offer one of the highest levels of sensory security on the market while preserving the authenticity and nobility of a single-piece natural cork stopper.
2. Why choose a natural cork stopper instead of a microagglomerated or technical closure?
While technical closures offer consistency and standardisation, natural cork remains unmatched for age-worthy wines. Its unique cellular structure enables ideal, stable, and natural micro-oxygenation (OTR) over time. It is the only closure that actively contributes to the evolution, balance, and refinement of fine wines in bottle, while also conveying the premium image consumers associate with the highest-quality wines
3. Where does the cork used by Parramon Exportap come from?
We work exclusively with locally sourced raw material. Our cork is sustainably harvested from Spanish cork oak forests, with full respect for the Mediterranean ecosystem. By controlling the entire process — from harvesting in the forest to production in our facilities, established in 1956 — we guarantee complete traceability and minimal environmental impact.
4. What customisation and branding options do you offer wineries?
We understand that the cork stopper is often the consumer’s first physical interaction with the wine. That is why we offer state-of-the-art laser branding for both the body and the ends of the cork, allowing wineries to reinforce their identity with precision and elegance.
5. What sets Parramon Exportap apart from large multinational manufacturers?
Our key difference lies in our exclusive approach and deep specialisation. We work closely with wineries to create premium cork stoppers that become the finishing touch for their finest vintages. By focusing on uncompromising quality, we provide responsive service, close technical support, and exceptional attention to detail — ensuring that every cork is not simply a closure, but an element that enhances and elevates the prestige of the brand.
6. Is cork a sustainable material?
Cork is one of the most sustainable materials used in the packaging industry. Cork oak trees are never cut down to harvest cork: the bark is carefully stripped by hand and naturally regenerates over time. After harvesting, the tree can absorb up to five times more CO₂ than before stripping, making cork’s carbon balance potentially negative. In addition, natural cork stoppers are fully biodegradable at the end of their life cycle. At Parramon Exportap, all our raw material comes from certified cork oak forests, with complete traceability from the forest to the bottling line.
