Designation of a bottle oversize for a champagne with the volume of three litres or the content of four normal bottles. However, the name is not protected of origin, but can be used freely for sparkling wines or wines. Jeroboam was the first biblical name for bottle oversizes that was first used by winegrowers in Bordeaux (i.e. not in Champagne) in 1725. In Bordeaux, however, this bottle size for still wines is called double magnum. Confusingly, in Bordeaux for still wines, the name Jeroboam is also used for other volumes: until 1977 for bottles with a volume of four and a half (six bottles) and from 1978 with a volume of five litres.
