Very large champagne bottle (8)

I believe the answer is:

jeroboam

(Other definitions for jeroboam that I've seen before include "'Large wine bottle, equal to four standard ones (8)'" , "Very large wine bottle named after old king of Israel" , "Very large wine bottle named after Israeli king" , "Large bottle of champagne; a Rome job (anag.)" , "Four-times bottle size" .)

I've seen this clue in the Sydney Morning Herald.
