As the leading company in the cork industry, we are permanently committed to guaranteeing the quality of its products. When it comes to eliminating TCA, i.e. the chemical compound responsible for the musty odour and "cork taste" in wine bottles, Amorim Cork adopts strict curative measures.
To eliminate TCA, Amorim Cork uses specific cleaning and treatment processes aimed at removing the unwanted compound from the cork. In addition, the company constantly invests in research and innovation to develop new techniques and technologies that help prevent and eliminate TCA.
Thanks to Amorim Cork's commitment to quality and innovation, its products are among the best on the market when it comes to eliminating TCA and guaranteeing the full satisfaction of its customers.
ROSA
With the aim of eliminating TCA and other volatile compounds that adulterate the characteristics of cork, Rosa (Rate of Optimal Steam Application) technology was launched in 2004.
This system is an essential stage in the treatment of granulated cork, using steam under controlled conditions to eliminate these compounds.
After implementing ROSA, batches of cork granules are analysed by gas chromatography to quantify those compounds to the level of parts per trillion.
ROSA Evolution
Between 2007/2008, ROSA was adapted to natural cork stoppers and this new technology was called ROSA Evolution.
This innovative technology works by using vapour under controlled conditions, but with less energy consumption/unit of time in order to avoid deformation of the natural stoppers. By increasing the residence time of the natural stoppers in ROSA Evolution, reductions in TCA and other volatile compounds have been achieved, similar to those obtained in granulates in ROSA.
