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)
