From Trees to Bottles: The Journey of Corks

What would a bottle of wine be without a cork? Aside from the obvious bottle shape restriction, it would definitely not taste the same if the wine was not stored using this traditional method.

So what is cork’s role in wine, and how did it become key in preserving the flavor of the contents? Like any great story, this one is a bit complicated.

Keep reading to learn how corks are made, from the trees they come from to their development as a wine preservation method.

Harvesting the Cork Oak Trees

First, workers remove the rough outer bark of the tree using large axes or specialized tools. They then set aside this outer bark to dry for use in other applications. Afterwards, the tree regenerates its bark, a process that can take up to nine years.

Once the tree’s cork material has fully grown back, skilled laborers carefully strip it in thin layers using a specialized tool called a plow. They subsequently sort and grade these layers based on their thickness and quality. Finally, craftsmen boil and shape the wood cork into various products, such as wine corks or flooring tiles.

Curing the Cork

This process involves letting the cork bark dry out for several weeks, exposing it to sunlight and air to promote natural oxidation. The bark is then boiled in water to remove impurities and soften the cork’s texture.

After boiling, the cork is then cut into the desired size and shape and left to dry for a few more days. This process ensures that the cork is free of any moisture and ready to use.


One begins by choosing a cork of the desired size and quality to punch a cork. Then, they use a cork punch, a sharp tool resembling a large needle, to create the hole. Placing the cork on a stable surface, they drive the punch into it using a mallet or hammer.

They then rotate the punch to create a clean, circular hole in the cork. If a larger hole is needed, they can repeat the process. Finally, they remove the cork from the punch, and it’s ready for use as needed.

Distribution Process

It involves several steps, starting with sourcing the cork from cork oak trees and transforming it into usable products. These products are then packaged and stored in warehouses before being transported to distribution centers. From there, the products are distributed to retailers who sell them to consumers.

The process requires careful planning, coordination, and transportation to ensure that the cork products reach their final destination in a timely and cost-effective manner. Effective distribution processes are vital in meeting customer demand and sustaining the market for cork products.
