Large Format
Sometimes bigger is better. While most people are familiar with the magnum 1.5L size bottles, there are also individual names for even larger sizes: a 3.0L is called a double magnum, a Jeroboam is 4.5L or equivalent to six standard 750ml bottles. Then we get into the Rehoboam (4.5L sparkling wine), Imperial (6.0L), Salmanazar (9.0L), Balthazar (12.0L), Nebuchadnezzar (15.0L), and Solomon aka Melchoir (a whopping 18 litres!)
