Why natural cork?
Natural cork is made from the bark of the cork oak tree. This organic material has an intricate cellular structure similar to a honeycomb which creates a compressible, impervious material that is resilient to environmental changes such as temperature and moisture. Natural cork is the only material that can adapt to the internal irregularities of the neck of a wine bottle ensuring proper sealing even if the glass expands or contracts during storage or shipping.

The maturation of wine finished with a natural cork is predictable as oxygen ingress with natural corks is largely a result from diffusion. Additionally, the physical properties of natural cork interact with wine during the maturation process by developing its character and impacting the creation of the bottle bouquet - the aroma developed during aging.

What size cork do I need?
Choosing the right size cork for your bottle and maturation process is essential for ensuring the ideal evolution of the bottled wine. Cork measurements are typically expressed in millimeters with the length of the cork first and the diameter second.

The diameter of the cork is the most important measurement for creating the proper seal. A natural cork stopper should be at least 6mm wider than the smallest diameter of the neck of the bottle. However, if the cork is compressed by more than 33% of its total diameter when inserted into the bottle, the honeycomb-like cellular structure of the cork may become damaged and impact the quality of sealing. 24mm is the most common cork diameter. This size fits most industry-standard wine bottles.

The second dimension, the length of the cork, also can affect the quality of the seal. Typically, longer cork stoppers are associated with longer bottled maturing, but choosing the appropriate cork length for the bottle will prevent leakage or poor sealing.

What grade cork do I need?
Natural cork is typically classified into categories based on several criteria including visual appearance, density, humidity, surface treatment, extraction force, etc. The highest quality is Flor or Flower grade with the smallest quantity and size of pores. From highest quality to the lowest, traditional classifications include: Flor, Extra, Super or Superior, 1st, 2nd, 3rd, 4th and 5th.

High grade corks are typically used for bottling quality wines for longer periods of cellar aging. This is because the higher density corks create a better seal and offer a smooth aesthetic with fewer cracks and no greenwood. The Cary Company sells natural corks in Flor, Extra, Super and 1st quality to help you ensure a proper seal.
