New Leadership
Imperial Cork is a brand with over a century of heritage in the cork stopper industry. Today it is reborn under new ownership — stronger, more agile, and with a truly global vision.
Leading this new chapter is Quin Amorim, globally recognised as one of the world's foremost ecommerce and digital markets experts. With a unique vision to combine Portuguese artisan excellence with worldwide online distribution, Quin brings a new dimension to Imperial Cork: making the world's finest cork stoppers accessible to wineries anywhere on the planet.
We are not the company of before. We are the evolution that heritage always deserved.
The new Imperial Cork has no legal connection to the previous company of the same name. We share the heritage of the name and the love of the product — everything else is entirely new.
Our Story
The story of Imperial Cork is inseparable from the story of wine itself. Founded in 1922, we have navigated a century of transformation in the wine industry while upholding one immutable principle: only the finest stoppers deserve the Imperial Cork name.
From the cork oak — the most noble of Mediterranean ecosystems — to the world's most demanding wine cellars, every stopper we make carries decades of knowledge, technical precision and an uncompromising love for the perfect product.

Our manufacturing process is a sequence of rigorously controlled operations, where each step determines the final quality of the stopper that reaches your cellar.
Cork planks are boiled twice to clean them, extract water-soluble substances, increase thickness and make the cork more supple and elastic.
A resting phase flattens the planks, followed by manual grading and separation by quality class before cutting into strips.
Strips are punched with a hollow drill to produce cylindrical stoppers. Dried to achieve optimal 4-8% humidity.
Grinding and polishing to achieve final specified dimensions with tolerances of ±0.5mm in length and ±0.4mm in diameter.
Each stopper is analysed by cutting-edge 3D electronic selection machines, complemented by manual selection, to guarantee correct quality grade.
Automatic washing and disinfection with hydrogen peroxide to eliminate microorganisms. Rigorous microbiological control on every batch.
Automatic ink or fire branding with the winery's logo, name, vintage or any graphic element specified. Your identity on every stopper.
Surface coating with silicone and paraffin blend to ease insertion and extraction, improve sealing and isolation. Vacuum packed with SO₂.

Knowledge & Insights
Wine Science
Unlike any synthetic or metallic alternative, the natural cork stopper is the only closure system that allows controlled micro-oxygenation — the process that enables wine to develop complexity and bouquet over time. We explore the science behind this unique property.
Sustainability
The Portuguese montado is one of the Mediterranean's most biodiverse ecosystems. Discover why this unique habitat is irreplaceable.
Quality Control
2,4,6-trichloroanisole is wine's number one enemy. Our process guarantees TCA levels below the human detection threshold of 2 ng/L.
