M. A. Silva has developed an individual cork testing method to deliverguaranteed TCA free corks*. Our process tests for releasable TCA, down to non-detectable levels (0.5ng/L) and eliminates bad corks from the supply chain. This fully automated process is based on cutting edge gas phase spectroscopy and available for high end natural cork to seal ultra-premium wines. It inspects every single cork one by one to detect any trace of cork taint leaving no margin of human error. The one-by-one testing process is the latest innovation of M. A. Silva's commitment to provide TCA free corks. 



Over the last 40 years we have established ourselves as an industry technology leader. Our proprietary cork cleaning processes are recognized worldwide and this new testing method is a game-changing technology in the cork industry. 

With the implementation of this new state-of-the-art testing technology we once again demonstrate our determination to be the leading manufacturer of the finest premium cork.
