Cork harvesting is performed in six stages: 1. The major cork producing nations provide 2,200,000 hectares (5.4 million acres) of natural cork forest.
Cork harvesting is done in a steady cycle that promotes healthy growth to the tree over its expected lifespan of over 200 years. At the same time, the edge of the axe is twisted so as to separate the outer from the inner bark. The first harvest, which is known as “desbóia”, produces cork of a very irregular structure which is too hard to be easily handled. This is the so-called virgin cork which will be used for applications other than cork stoppers (flooring, insulation etc. The first Portuguese regulations protecting cork oak trees date to 1320 by then King Dinis. Cork is harvested in a steady cycle that promotes healthy growth to the tree over its expected lifespan of over 200 years. Nine years later, the second harvest produces material with a regular structure, less hard, but still not suitable for cork stoppers – this is known as secondary cork. Cork harvesting is performed in six stages: 1. The tree itself is never felled. A vertical cut is made in the cork, choosing the deepest crack in the cork bark. After the first plank has been stripped, the operation is repeated over the whole trunk. Opening.
When the edge of the axe is applied to the strip, a hollow sound of tearing is heard if the cork is going to come off easily.

Opening. All the piles are constructed taking into account strict specific rules defined by the International Code of Cork Stopper Manufacturing Practice – ICCSMP, so as to allow the cork to stabilise.
), since its quality is far from that necessary to manufacture stoppers.
Cork is extracted only from early May to late August, when the cork can be separated from the tree without causing permanent damage. Typically, virgin cork is not removed from saplings until the 25th year, and reproduction cork (the first cycle) may not be extracted for another 9-12 years. All Rights Reserved. The harvesting of the cork oak is an ancient process that can only (and should) be done by experts: the descortiçadores.

The larger the planks extracted, the greater their commercial value. The axe is twisted between the trunk and the cork strip to be extracted. At this time of year the cork comes away easily from the trunk because the tree is growing, the new, tender cork cells being generated break easily.

The axe is twisted between the trunk and the cork strip to be extracted. The plank is removed from the tree with care so that it does not split. However, this first harvest almost always produces poor quality or "virgin" cork (Portuguese cortiça virgem; Spanish corcho bornizo or corcho virgen ). From then on, the cork oak will supply good quality cork every nine years for around a century and a half, producing, on average, 15 bark harvests throughout its life. Cork harvesting is done entirely without machinery, being dependent solely on human labour. This is the so-called “amadia” or reproduction cork. Another 9 to 12 years is required for the second harvest, and a tree can be harvested about twelve times in its lifetime. Founded in 2008, Cork ReHarvest has led the cork recycling movement in the US and Canada, helping to collect and recycle some of the billions natural corks that are produced each year.
Usually five people are required to harvest the tree's bark, using a small axe. 1. Bark from initial harvests can be used to make flooring, shoes, insulation and other industrial pr…
Virgin cork (or 'male' cork) is the first cork cut from generally 25-year-old trees. A vertical cut is made in the cork, choosing the deepest crack in the cork bark. The first harvest, which is known as “desbóia”, produces cork of a very irregular structure which is too hard to be easily handled.
