Key product features:

• Material: Natural cork, obtained from the bark of the cork oak, is characterized by exceptional elasticity and the ability to regain its original shape after being compressed
• Standard dimensions: 23x40 mm - perfect fit for most wine bottles
• For long-term storage: The cap ensures a tight seal while allowing the exchange of gases, which prevents the drink from oxidizing and losing its flavor

How to use:

1. Preparing the corks: Soak the corks in hot water for about 3 minutes to increase their elasticity.
2. Closing: Use a corkscrew to place the cork into the neck of the bottle
3. Stabilization: Once sealed, store bottles upright overnight to allow the cork to adjust to the inside of the bottle
4. Long-term storage: Store bottles horizontally to prevent the corks from drying out and maintain proper gas exchange

What is the difference between natural and agglomerated cork?

Natural cork comes from a single piece of cork oak bark and retains all the properties of this raw material, such as elasticity, flexibility and optimal air permeability. It is particularly recommended for closing wines and beverages that require long storage.

In contrast, agglomerated corks are made from finely ground bark, bonded with adhesives. Although they are more economical, they do not offer the same properties as natural corks – especially in terms of tightness and influence on the maturation process.
