How many times can a cork oak be stripped?
Over the course of its lifetime, a cork oak may be stripped around 17 times, at intervals of at least nine years, which means that the harvesting of the cork will last 150 years, on average.
The first stripping is called "desbóia" from which the virgin cork is obtained, which has a highly irregular structure and hardness that make it difficult to process.
Nine years later, when the second stripping takes place, the cork, known as "secundeira", has a regular structure which is not as hard.
The cork from these first two harvests is not fit for the manufacture of stoppers and thus used in other applications for insulation, flooring, decorative items, among others.
From the third and following strippings the "amadia" or reproduction cork is obtained. This cork has a regular structure, with a flat front and back and the ideal characteristics for the production of natural, quality cork stoppers.
Synthetic closures are getting better all the time; isn’t it only a matter of time before existing problems are resolved?
It’s good that all closure manufacturers seek to improve their product. However, according to recent research, synthetic closures still have some way to go, especially in relation to oxidation and flavour ‘scalping’.
Cork on the other hand also continues to improve and retains all the benefits of a natural wine closure. So even if parallel advances are achieved by the plastic stoppers, we will be able to retain cork’s advantageous departing position.
