June brings together two distinct natural rhythms: the cork oak forest and the vineyard.

In the vineyard, the vines are in full growth, steadily developing through the season. Each day contributes to what will later become the harvest, shaped by time and climate.

In the cork oak forest, June marks the start of the cork harvesting season - one of the most important and active periods of the year. It is a time of precision and teamwork, where the bark is carefully removed by hand, respecting the natural cycle of the tree.

Two landscapes, moving at different rhythms, both guided by seasonality and nature.

From forest to vineyard, June is a reminder that every result begins long before it is seen.

This World Environment Day, we celebrate the power of natural materials.

Cork stands out for its unique combination of natural performance, renewability, and recyclability.

Harvested without harming the tree, it helps preserve biodiversity, supports healthy ecosystems, and contributes to a more circular future.

Every cork product begins in a forest that continues to grow, regenerate, and capture carbon, creating lasting environmental benefits far beyond its application.

Today, we're proud to be part of an industry that demonstrates how sustainability and performance can go hand in hand, proving that the best innovations often start with nature.

Wineries don’t just need closures.

They need systems they can trust.

CWINE is part of a new generation of technical cork closures designed for precision winemaking environments, where consistency and control are essential.

Using advanced supercritical CO₂ extraction technology, CWINE reduces TCA to below detectable levels (

Wine has a way of bringing people together - whether it’s a quiet dinner, a celebration with friends, or simply the end of a long day.

This National Wine Day, we’re celebrating the moments, memories, and conversations that begin with the simple act of uncorking a bottle.

At Portocork America, we’re proud to play a small part in preserving those experiences, one cork at a time. 🍷

Tradition built the cork industry.
Technology continues to shape its future.

What was once seen only as a traditional wine closure is now supported by innovation, advanced quality control, and continuous research.

At Portocork America, technology plays a key role in delivering reliable cork stopper solutions that meet the demands of wineries - combining sustainability with technical performance.

From anti-TCA technologies and individual cork screening to rigorous sorting and quality assurance processes, innovation ensures cork closures wineries can trust.

A natural solution, supported by innovation.

Did you know most of the world’s cork comes from Portugal?

Home to around 720,000 hectares of cork oak forests, Portugal is responsible for nearly 50% of the world’s cork production.

For centuries, Portuguese cork oak forests have played a key role in the wine industry - combining sustainability, tradition, and innovation in every natural cork closure.

A tradition rooted in nature.

A material trusted by wineries worldwide.

What winemakers look for in a cork closure?

Winemakers don’t choose a cork stopper by chance.

They look for consistency, reliability, and a closure that protects the wine’s evolution over time.

Here’s what matters most:

- Consistency
- Sustainability
- Aging potential
- Technical performance
- A premium opening experience

Cork remains the closure of choice for wineries that care about quality, aging potential, and authenticity.

From Portugal’s cork oak forests to wineries around the world, every cork tells a story of tradition and innovation.

The story of cork begins in the forest, in the Montado.
Cork comes from the cork oak tree, harvested without cutting the tree and allowing it to regenerate naturally over time.

These forests play a vital role in:

- Supporting biodiversity
- Preventing desertification
- Capturing carbon from the atmosphere

For the wine industry, cork is more than a closure - it is a connection between nature, tradition and sustainability.

A cork holds more than wine.

It holds time, seasons, and the care of countless hands. Every bottle carries a story waiting to be told, a journey waiting to be experienced.

And when the cork is lifted, the world seems to pause - just long enough to savor the moment.
