These natural cork stoppers are shaped, chamfered, colmated, sorted, washed, coated, treated, marked and packaged. They are designed for still wines and are made of planks of 100% Spanish natural cork.

The cork’s seasoning time is controlled using a FIFO warehouse control system.

The report which is produced for each shipment includes the following parameters: humidity, diameter, length, ovalisation, density and extraction and insertion force.
The following samples are taken for this analysis: for shipments of 0 to 5,000 stoppers, a test sample of 5 stoppers; for 5,000 to 50,000 stoppers, a test sample of 10 stoppers; for 50,000 to 200,000 stoppers, a test sample of 25 stoppers; and for 200,000 to 400,000, a test sample of 50 stoppers.
The microbiological characteristics, maximum powder content and capillarity are tested in batches by sending samples to an external laboratory in a sterile clinical analysis container. This report is available for any customers who wish to read it.
