What Is The Neutrocork®️ Stopper?

Functional, accessible and with impeccable sustainable credentials – each stopper retains up to 392g of CO2 – Neutrocork is recommended for fast-rotation wines.

The Neutrocork® stopper offers great structural stability, resulting from a uniform-sized micro cork granule composition pressed into individual moulds. Due to this manufacturing process, there will be no bottle to bottle variation. With an attractive appearance and easy extraction, it stands as an extremely competitive natural closure in terms of both performance and price.

This stopper is available in the following sizes: 38x24mm, 44x24mm and 44×25.5mm.
