ROSA

ROSA (Rate of Optimal Steam Application) technology is a proprietary technology developed by Amorim to eliminate TCA (2,4,6-Trichloroanisole) and other volatile compounds that may affect the natural properties of cork and can cause the commonly referred to “cork taint” in wine bottles. 

Introduced in 2004, ROSA technology uses controlled steam distillation to treat cork granules, ensuring they are free from undesirable compounds, without compromising the cork’s natural qualities.

ROSA technology is integrated into Amorim’s overall quality control process. The technical cork stoppers that undergo ROSA treatment are subjected to additional tests and evaluations to ensure they meet strict quality standards, reducing the chances of tainted or defective stoppers reaching the market.

In this way, through a natural process, Amorim Cork is able to enhance the overall performance of its agglomerated and micro-granulated cork stoppers, providing a reliable closure that preserves the quality of the wine in the bottle over time.

ROSA Evolution

Between 2007/2008, ROSA technology was adapted to be applied to natural cork stoppers. This new technology, called ROSA Evolution, is based on using vapour under controlled conditions as the ROSA technology, but consuming less energy per unit of time in order to prevent deformation on natural stoppers.
