Natural Cork
Cork is the bark of the cork oak (Quercus Suber L. ), which means it is a 100% natural plant tissue. It is formed by a hive of microscopic cells filled with a gas similar to air and covered mostly with suberine and lignin. In its chemical composition other compounds are also identified, although with less expression, such as polysaccharides, ceroids and tannins.
In a single cubic centimetre of cork there are almost 40 million cells – about 800 million in a single cork stopper.

T4T SNIFFER
T4T is a sensory olfactory quality control method designed for high quality natural cork stoppers, allowing the selection of stoppers with guaranteed non detectable TCA.
The T4T Sniffer process individually analyses the presence of TCA, mould and other abnormal sensory deviations in each natural cork stopper, using an olfactory control method carried out by JGR CORK’s specialised professionals.

JGR W-ONE
JGR W-ONE is a quality analysis and control technology designed for premium quality natural cork stoppers, allowing the selection of stoppers with non detectable TCA guarantee*. This technology individually analyses the presence of TCA in every natural cork stopper, in seconds, using an innovative technology of rapid chromatography.
This analysis, being highly accurate, allows to detect any cork containing more than 0.7 ng/L of TCA* (parts per trillion), being automatically removed from the process.
- Cork stoppers with TCA-Free guarantee
- Corks 100% individually tested by our equipment
- TCA analysis with high levels of accuracy through a highly sensitive process
- Buy Back Bottle” Warranty Policy – Your Wine Bottle Warranty

O3 OZONE
Ozone Thermal Sterilisation Chamber is an odour-cleaning technology for cork that aims to make the cork stopper more sensorially clean.
Cork stoppers enter a hermetically sealed chamber at a temperature of approximately 0ºC for thermal stabilization for 48 hours. The Ozone – O3 chamber facilitates the disinfection of the cork stopper at any stage of the process by decreasing the probability of TCA and other odours through the action of ozone.
