Today's word is "nebuchadnezzar". The largest wine commercially available to my knowledge, it holds 15 liters of wine, about 20 standard-size bottles. The other sizes, from next-largest to smallest, are Balthazar (12L), Salmanazar (9L), Imperial (6L), Methuselah (6L), Rehoboam (4.5L), Jeroboam and double magnum (3L), magnum (1.5L), standard, half bottle (375ml), and split (1/4 bottle or 187 ml)
When buying a nebuchadnezzar or something more modest, keep in mind that a larger volume of wine will age far more slowly than a standard 750 ml bottle, especially a cabernet/Bordeaux type of red. A lot of people have enjoyed a specific vintage of a red wine in a standard bottle and then bought a larger size for a special occasion and have been really disappointed when they learned that it really wasn't drinkable yet.
If you do splurge, invite me over to drink it, won't you? I'd be happy to bring the cheese and crackers...
