WHAT WE DO

ADVANCED VINICULTURAL CORK SOLUTIONS

High-performance natural and technical stoppers tailored to precise enological parameters.

We specialize in high-performance natural, technical, and synthetic cork stoppers, engineered to preserve wine profile, ensure optimal OTR management, and guarantee TCA-free performance. Our portfolio offers full dimensional and structural flexibility, allowing for complete customization according to your specific winemaking parameters. We tailor our products by precisely calibrating density, extraction force, and surface treatments to match your bottling line and aging requirements.

Natural

Crafted from premium-grade bark, our natural closures are the definitive choice for sealing prestigious still wines. Due to their unique, inherent physicochemical characteristics, these stoppers facilitate optimal micro-oxygenation, allowing for superb wine maturation and flawless long-term aging in the bottle. Every batch supports tailored dimensional calibration and specialized surface treatments to match your exact bottling line requirements. To elevate your brand aesthetics, the cork body allows for high-definition, traditional fire branding alongside complete aesthetic customization. We also remain fully receptive to designing bespoke variations using alternative finishing protocols upon your request.
