Alcoa recently announced that its Alcoa Closure Systems International business has begun the commercial launch of VinTegra(TM), its new glass stopper closure system for wine bottles as an alternative to corks and synthetic stoppers. Alcoa will supply the new closures to selected North America winery partners for initial use in their premium wines. The new system, already in commercial production in Europe under the trade name Vino-Lok, will offer the wine industry a high quality and elegant alternative to traditional wine closure systems. The VinTegra closure looks like a decorative decanter stopper, and it is recyclable. Made with flexible O-rings, the stopper provides a sterile seal, preventing contamination or oxidation. An aluminum over-cap and traditional neck sleeve will ensure mechanical protection and tamper evidence. The VinTegra glass stopper is the first product in a larger portfolio of wine closures that Alcoa CSI is currently developing as an alternative to traditional wine stoppers.
