Introducing Nomacorc Green Line
Nomacorc Green Line is a category of closures called PlantCorc™, derived from sustainable, renewable sugarcane-based raw materials. Driven by a steadfast commitment to innovation, sustainability, and continuous improvement, Nomacorc Green Line offers dramatic improvements in wine closure Performance, Design, and Sustainability.
Green Line closures are based on Nomacorc’s patented & proven co-extrusion manufacturing technology, which ensures bottle-to-bottle consistency, and eliminates faults due to oxidation, reduction, off-flavors associated with TCA and other contaminants.
The natural look and soft-feel skin ensures trouble-free bottling performance and provides customers a smooth extraction and reinsertion closure experience. With a culture committed to sustainability and an ultimate product vision of carbon neutrality, all Nomacorc Green Line closures are certified to contain plant-based raw materials, substantially reducing carbon footprint. PlantCorcs™ are produced using sustainable manufacturing processes powered by renewable energy and are fully recyclable.

🌿 PlantCorc™ Technology & Renewable Raw Materials
PlantCorc™ technology is a new, nature-inspired category of high-performance wine closures. Building off the success of Nomacorc’s oxygen management research initiative, this latest innovation couples the sustainability of renewable plant-based raw materials with the consistency and predictability of co-extrusion technology.
In 2013, with the launch of Select Bio, Nomacorc developed the world’s first zero carbon footprint closure and began the journey to apply this technology to all of their closures — today known as Nomacorc’s Green Line.
PlantCorc™ technology utilizes plant-based raw materials derived from sources such as sugarcane. The plant-based ingredients are harvested using techniques ensuring there are no negative effects on the food supply or the environment.

🔬 Performance
Based on years of oxygen management research studying various winemaking styles and in collaboration with leading wine institutions and winemakers, consistent control of oxygen ingress post-bottling is fundamental to the Nomacorc Green Line.
While maintaining the traditional bottle-opening experience, the precision of co-extrusion technology benefits all wines, including those of the highest quality requiring wine preservation up to 25 years.
Nomacorc Green Line closures deliver trusted performance including: TCA- and migration-free composition, smooth and easy extraction and reinsertion with no crumbling or breakage, reliable bottling performance, and clean, safe, compliant product compositions.
