A Jeroboam is a very large bottle of wine or Champagne, larger than a magnum but smaller than a Rehoboam. There are two sizes depending on the beverage: a Jeroboam of wine holds 4.5 liters or six regular bottles, while a Jeroboam of Champagne—also known as a double magnum—holds three liters or four regular bottles. Incidentally, Jeroboam was the king of northern Israel around 900 b.c. See also Balthazar, Imperial, magnum, Methuselah, Nebuchadnezzar, Rehoboam, and Salmanazar.
