The craft
We believe in the value of time, in conscious craftsmanship and innovation that respects nature. Each cork is the result of the wisdom passed down from generation to generation. At Oller, perfection comes from striking a balance between tradition and progress.
Terroir
In Empordà and Les Gavarres, our work is rooted in the land and open to the world.
The cork-oak forests are our origin, our inspiration and our future. Caring for cork is caring for the culture that defines us.
From here, we export excellence to the most prestigious wineries in the world.
World of wine
Corks are part of sparkling-wine culture.
That is why we promote and participate in meetings, tastings and events with the professionals shaping the sector today and tomorrow.
Advisory services
Working with Oller means forging a relationship based on trust.
We provide technical advice based on tastings, tests and analyses, as well as strategic guidance to help wineries find the best solution for each sparkling wine, market and ageing style.
Our clients don’t just get a product; they get a team that listens, supports and monitors the performance of each cork. Because the success of a great sparkling wine also depends on its stopper.
Two sides of the same coin
01 Mechanical performance advisory services
Each winery has different processes and machinery. That is why we work closely with the client to:
- adapt the cork to the bottling process and production pace
- integrate it with winery machinery to prevent risks
- optimise dimensional recovery to ensure safe, smooth, perfect opening
This precision guarantees industrial safety and an opening experience worthy of an exceptional sparkling wine.
02 Sensory performance advisory services
The cork isn’t neutral. It influences the evolution of sparkling wine and its final expression.
We support wineries through:
- tastings and comparative testing
- sensory and chemical analyses
- guidance to ensure the cork suits the ageing type and aromatic profile of the sparkling wine
Our goal is clear. For each bottle to reach the consumer exactly as the winery intended, with its identity, freshness and precision intact.
One concept of corks.
Solutions tailored to each type of sparkling wine.
Natural
Natural corks are the classic among classics. And each piece is one of a kind.
At Oller, we select them one by one strictly based on their density and visual consistency to ensure impeccable quality, both in function and appearance.
It is the most authentic, prestigious way to preserve a great sparkling wine.
A gesture of craftsmanship that connects the soul of the forest with the expression of the wine.
Why natural?
Natural corks offer unique advantages:
- Respect for the wine: the natural discs in direct contact with the wine promote harmonious evolution faithful to the winemaker’s vision.
- Antioxidant properties and OTR control: they help preserve freshness and elegance while adding complexity over time.
- Durability and strength: they withstand internal pressure perfectly, even over extended ageing.
Our commitment to natural cork also means fewer chemical products are used, which is better for the environment.
1D, 2D and 3D options
More discs mean superior precision, stability and protection of the sensory profile.
3D. Three natural discs.
Designed for premium ranges and extended ageing.
The most respectful evolution for the wine.
2D. Two natural discs.
The industry standard for quality sparkling wines.
1D. One natural disc.
An efficient solution for young sparkling wines to be enjoyed without ageing.
Specialities
Oller’s special corks are truly bespoke creations.
Unique projects for one-of-a-kind bottles. Designed for exceptional formats such as jeroboams or methuselahs, they combine innovation, craftsmanship and meticulous attention to detail.
Through precise craftsmanship and natural innovation, we create corks that reflect the personality of each sparkling wine and the vision of each winery.
For these tailor-made pieces, we select the materials specially, use specific processes and implement exhaustive controls to ensure an incomparable result. Because some sparkling wines deserve a cork designed exclusively for them.
Jano
The fusion of tradition and technology.
Next-generation technical corks offering highly stable performance, controlled permeability and outstanding consistency among units.
Perfect for wineries that need reliable, consistent results without any variations in look and feel.
These corks are designed to respect the essence of the sparkling wine, preserving its aromatic nuances and purity over time.

Knowledge and R&D
At Oller, research, development and innovation are in our DNA. The R&D&i department is a strategic pillar and constant source of progress and inspiration. We work with scientific rigour and a creative mindset to understand every detail: from antioxidant contribution and structure to influence on evolution, mechanical behaviour, aroma and the final character of the sparkling wine.
We develop and implement the most advanced quality control and sensory analyses to ensure safe corks tailored to our clients. We go further, actively collaborating with research centres, oenological institutes and laboratories both locally and internationally to validate new processes, experiment with materials and get data that allows us to perfect every detail.
Science provides answers, but it also inspires us to dream and anticipate. Our innovation starts with listening to wineries’ needs and transforming them into solutions that make a difference: corks that preserve the wine’s vitality over time, maintain the personality of each bottle and enable an authentic, memorable sensory experience.
Through a clear commitment to R&D&i, we continue to forge new paths: new manufacturing technologies, more sustainable processes and pioneering studies on the relationship between corks, wine and time. Our goal is clear: to be trustworthy today and inspire the innovation of tomorrow, for the most demanding sparkling wines.
Research and innovation
At Oller, we propose a global vision of cork as a plant cell wall. We must understand this natural polymer beyond simplifications and generate new knowledge of this complex natural system.
We seek multidisciplinary knowledge and work with research centres that provide diverse, complementary perspectives: genomics, metabolomics, chemical composition, biotechnology and mechanical properties.
This global vision allows us to optimise cork structure and use environmentally friendly manufacturing techniques that enhance the properties of this material and the performance of each cork.
In the context of climate change, knowledge-based biological solutions are the only sustainable and environmentally friendly path forward.
