A party-size bottle of Champagne that holds the equivalent of eight regular bottles. It's the same size as an Imperial, which is usually used for non-sparkling wine. The Methuselah—named for the biblical patriarch said to have lived 969 years—is smaller than a Salmanazar but larger than a Rehoboam. See also Balthazar, Imperial, Jeroboam, magnum, Nebuchadnezzar, Rehoboam, and Salmanazar.
