The aluminium closure guarantees an absence of 2,4,6-trichloroanisole (TCA), the chief cause of cork taint, resulting in a significant reduction in wine spoilage. Corked wine containing TCA has an unpleasant characteristic odour. About 2 to 5% of all wine produced in the world each year is wasted, spoiled by products of decay resulting from closures made out of traditional materials.
With aluminium closures, by contrast, the special wine aroma emerges only when it comes into contact with the air as it is poured into the glass or carafe, and not before it has left the bottle. A simple twist of the aluminium closure and the wine is presented in its natural condition. The visibility of the closure in the supermarket or shop also guarantees it has not been tampered with prior to purchase.
Aluminium closures, with a liner specially developed for wine, provide an optimum seal, preventing any liquid leaking and also guarantee the wine’s steady ageing, eliminating premature oxidation. Until its ultimate destination – decantation into the glass – wine kept in bottles sealed with aluminium closures enjoy the highest possible degree of protection with nothing to detract from the enjoyment of the wine. Cheers!
