Innovation
Searching for the Perfect Cork
Our constant search for improvement takes us further. Our goal is to achieve perfection, cork by cork, bottle by bottle. For this reason, 15% of our employees are dedicated to ID and Quality Control.
Quality
We are leaders in Quality Control
- Traceability of cork from the forest;
- Purchase of high quality raw material directly in the forest;
- Sampling and analysis of the raw material directly in the forest;
- Most advanced boiling technology in the sector:
- 100% of natural cork stopper production is subjected to the TCA and off-aromas Extraction Circuit;
- We have the highest ratio of laboratory analysis per stopper sold in the world;
- More than 5 million corks consumed per year for quality control analyses;
- In-house laboratory with chromatography equipment operating 24 hours / 7 days a week;
- Guaranteed minimum: 3 control points in the production of natural cork stoppers;
- More than 250,000 chromatographic analyses performed annually;
- 15% of employees dedicated to quality control and R&D.
Technology
New TCA extraction technology: natural corks without TCA*.
Once again, we have redefined quality by taking our natural corks to a higher level, thanks to the introduction of the second technology for extracting TCA and other off-aromas, PureCork.
The InnoCork Circuit is thus composed of two technologies - PureCork and InnoCork (introduced in 2007) - that are part of the production process and allow us to ensure that all natural cork stoppers are free of TCA and other off-flavors at no additional cost to our customers.
Each extraction technology is located at a different critical control point in the production line to ensure maximum efficiency, control and results.
* The corks have been shown to be free of TCA and other off-flavors in 99.85% of cases.
VAPEX
Granule cleaning technology for technical stoppers.
All the granulate used in the production of technical stoppers, 100% from our raw material, is submitted to the VAPEX process.
This is a treatment that extracts TCA molecules and other volatile compounds using steam under pressure.
This efficient batch treatment process guarantees a high sensorial uniformity of the granulate and allows traceability by batch.
DS100
DS100
100% INSPECTION (SINCE 2011)
In 2011, Cork Supply launched the industry's first natural cork stopper with no detectable TCA and an individual guarantee.
The DS100 is a non-invasive, non-destructive analysis performed by a panel of highly specialized testers that guarantees the elimination of corks with sensory deviations including TCA.
100% of the corks are inspected to detect all sensory deviations, including TCA, using our non-destructive "dry maceration" method.
Every cork in a DS100 order is 100% inspected by 3 sensory experts in a sequential manner. If one of these three specialists detects a sensory deviation in a cork, it is rejected and removed from the batch of corks.
As a sign of our commitment to our customers, we were the first company in the industry to offer a Bottle Buy Back guarantee.
However, our constant search for improvement takes us further. Our goal is to achieve perfection, cork by cork, bottle by bottle, 100% natural, environmentally friendly, and TCA free. We are getting closer to this goal with the world premiere of the new stopper: the natural cork stopper with guaranteed organoleptic performance control in all stoppers, for an exceptional result and maximum guarantee.
