Vino-Seal(TM) is a new glass closure developed by Alcoa as an alternative to traditional corks and synthetic stoppers for wine. With a design similar to a decorative decanter stopper, Vino-Seal(TM) uses an inert o-ring to provide a sterile seal, preventing contamination or oxidation. Whitehall Lane Winery of Napa Valley is using the new glass closure to top its premium 2003 Reserve Cabernet Sauvignon and 2003 Leonardini Vineyard Cabernet Sauvignon. (Photo: Business Wire)
