How can you tell an oak tree from a cork?

Unlike many other oak trees, cork oak is an evergreen and does not drop its leaves. The thick and knobbly dark grey bark which covers it is the portion known as “cork.” During cork harvest, the tree remains standing while large sections of its outer bark—the cork itself—are cut and peeled from the tree.

What does a cork plant look like?

The tree is usually about 18 m (60 feet) tall, with a broad, round-topped head and glossy green, hollylike leaves. Cork is obtained from the new outer sheath of bark formed by the inner bark after the original rough outer bark is removed. The outer sheath may then be stripped and will form again.

The Cork Oak Tree is found in the Mediterranean (Spain and Portugal.) Laws dictate that a tree must grow for 25-34 years before the first harvest. This is done by a person called an extractor and it is done in a special way to make sure the tree can continue to grow and produce more cork.

Why is cork called cork?

Its name comes from the Gaelic Corcaigh, which means marshy place. For centuries the abbey at Cork flourished and it was famous for learning.

Do Most trees have a layer of cork?

What does cork oak look like?

The cork oak (Quercus suber) is a medium-sized, evergreen oak tree. It grows southwest Europe and northwest Africa. It grows to up to 20 m, but in its native environment it is usually not that tall. The leaves are 4–7 cm long, dark green above, paler beneath, with the leaf margins often downcurved.



How long does a cork tree live?

200 years

Cork trees live on average 200 years, but there are cork trees that are 500 years old. They grow up to 75 feet tall. A cork tree is ready to be harvested after it is 40 years old.

Why do people smell a wine cork?

So back to why we smell the wine cork. The short answer is TCA. The taint kills any of the wine’s original aromas and usually creates a dull smell often described as wet cardboard, mold, rotten wood or fungus. If you get a whiff of any of those odors from the cork, your wine may be “corked”.

Why is wine not corked anymore?

The reason cork alternatives have became so popular is because of a period of decreased quality cork manufacturing during the 1980’s. Basically, winemakers were tired of getting low quality corks that would cause TCA ‘cork’ taint, so they switched.



Are we running out of cork trees?

We often get asked this question and the answer is quite simple: No. Absolutely not. The rise of alternative wine closures such as screw-caps, faux cork, plastic, etc., have certainly created less demand for real cork stoppers.

How much is cork worth?
