Lightness

Cork is a very light raw material, weighing just 0.16 grams per cubic centimetre, and can float.

Flexibility/compressibility

Each cork stopper is made up of around 800 million watertight cells. Among them is a gaseous mixture which allows it to be compressed to around half its thickness, without losing any flexibility, and to be decompressed and return to its original shape. This is what is called an elastic memory. Cork is the only solid which when compressed on one side, does not increase in volume on the other. This feature enables it to adapt to variations in temperature and pressure, without compromising its integrity as a stopper.

Impermeability

Thanks to the suberin and ceroids, it is practically impermeable to liquids and gases.

Decay resistant

Cork is highly resistant to moisture, and therefore to subsequent oxidation and decay.

Insulation

Cork is an excellent thermal, acoustic and vibration insulator. In relation to wine, the insulating properties of cork contribute to cork stoppers being the best protection against variations in temperature.

Biodegradable, recyclable and renewable

Cork is a natural raw material which is 100% biodegradable, recyclable and renewable. A recycled cork stopper is never used to manufacture a new stopper, but its recycling has endless uses, from materials for construction, fashion, sport, art, the aeronautics industry, among others.
