Natural corks are the natural choice for all types of wine as they combine pleasing aesthetics with excellent performance. There are different grades of natural cork, with the pinnacle being our 100% TCA free cork. Through our investment in technology, each cork can be examined for releasable TCA content (below the 0.5 ng/L detection limit, analysis performed in accordance to ISO 20752). Your wine demands the best: to ensure it will be drunk just as you intended, choose a cork that guarantees no interference or taint.
