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.
Isn’t it only a matter of time before winemakers understand the use of screwcaps and are able to adjust winemaking practices to accommodate this closure?
Post-bottling wine chemistry is a very complex issue and the closure is only one of a number of factors affecting wine development (others include the chemical composition of the individual wine, headspace volume and gas composition, free SO2, bottling conditions, etc).
Research is improving our understanding but wine researchers don’t yet know enough about how all the factors affect wine development to predict let alone control what will happen in the bottle.
Experts such as Dr Alan Limmer believe that the likelihood of reduced characters forming after bottling varies from wine to wine, vintage to vintage, placing severe demands on the winemaker wanting to control them.
