The ReServe Adaptor is inserted into the opened wine bottle to create an airtight seal. With an airtight seal in place, the user can be confident that only helpful pure Argon is being let into the bottle. To protect more than one bottle of wine at a time, simply use a ReServe Adaptor for each bottle. The Regulator supplying the Argon gas can be easily transferred from one ReServe Adaptor to any other ReServe Adaptor to protect multiple bottles of wine.
There are 3 ReServe Adaptor sizes: Standard Adaptors fit bottles from USA, France and Australia. Narrow Adaptors fit bottles from Italy, Austria, South Africa and South America. Narrow Adaptors also fit bottles for ports and most sparkling wines. Champagne Adaptors fit the Tête de Cuvée bottles (e.g., Dom Perignon and J).
