There's also a methuselah, which is a wine bottle holding approximately 6.5 quarts (a bit over a gallon and a half). I assume this is the American not the British quarts and gallons.
I also found this at a web site:
A magnum of wine is two quarts; a tappit-hen of wine or rum is a double magnum; a jeroboam
of wine or rum is a double “tappit-hen”; and a rehoboam (q.v.) is a double jeroboam.
