Our Quality Control Laboratory and the technical team backing up Production meet all winery requirements. The Cork Stopper Of all the natural products transformed by industry, undoubtedly cork is one of the raw materials with the widest range of applications. The cellular structure of cork tissue affords the cork stopper a good adherence to the bottle neck, something that cannot be achieved by any synthetic product. That is why the cork stopper is still the best-known closure for wine. Careful selection of raw materials means that corks are tailor-made for each application.
All corks undergo a washing procedure to disinfect and enhance their appearance.
After drying, corks are sorted according to required grades, and can be printed or fire branded. In order to ensure good sealing performance, a surface treatment is applied to the cork, which avoids penetration of wine, helps insertion during the bottling process, and allows easy pulling by the consumer. For bottles with Bar Top corks, a capsule made of wood, plastic or metal is added to the cork. Finished corks are vacuum packed in anti-oxidant polyethylene bags, ensuring their preservation. For approval, finished lots pass through a vast inspection plan.
