Natural properties of cork

Oxygenation

When the stopper is inserted into the bottle, it is compressed, gradually releasing the ideal amount of oxygen that the sparkling wine needs to age perfectly while it is stored in the bottle.

Impermeability

Thanks to the suberin, the natural cork discs ensure the sparkling wine remains sealed, isolating it from external elements like humidity, fungi and odors while also preventing wine or gas from escaping.

Ideal pressure

The cork’s compression capacity exerts the ideal pressure to retain the necessary carbon dioxide gas, preventing leaks and facilitating smooth uncorking by the end user.

Durability

The lignin and polysaccharides in cork give it great longevity and make it a very resistant and durable material that has proven to retain its characteristics over the years.

Lightweight

Cork is made up of 90% air, making it extremely light and facilitating its transport and handling, while maintaining its characteristic resistance and insulating capacity.

Natural and eco-friendly

Cork is a 100% natural and renewable product. It is sustainably harvested from cork oaks causing zero damage to the tree, which means it is possible to maintain hectares of protected forest.
