Rehoboam (4.5 L)

What is Rehoboam (4.5 L)? Rehoboam (4.5 L) is a large-format sparkling wine bottle holding exactly 4,500 ml, the equivalent of six standard 750 ml bottles. The format is used almost exclusively in Champagne, sitting between the Jeroboam (3 L) and the Methuselah (6 L) in the traditional large-bottle sequence. Its name follows the long-standing Champagne convention of borrowing Old Testament rulers — in this case Rehoboam, son of King Solomon and the first king of the Kingdom of Judah after the split of the united Israelite monarchy. Today the Rehoboam is a connoisseur's bottle, reserved for prestige cuvees, on-premise pours, and collector cellars rather than everyday retail shelves.

Origin of the Name and the Format

The Champagne trade has named its oversized bottles after biblical figures since the 19th century, shortly after the Bordeaux council formalized the 750 ml bottle as the standard reference unit in 1866. Once that standard existed, every larger format could be expressed as a clean multiple of it, and merchants needed memorable names to distinguish them on labels and invoices. Rehoboam, the six-bottle format, slotted neatly into a sequence that runs Magnum (1.5 L), Jeroboam (3 L), Rehoboam (4.5 L), Methuselah (6 L), Salmanazar (9 L), Balthazar (12 L), and Nebuchadnezzar (15 L).

It is worth flagging a common point of confusion. The same biblical-name system is used somewhat differently in Bordeaux still-wine practice, where Jeroboam denotes a 5 L bottle and Rehoboam is essentially absent from the vocabulary. In still wine, producers usually leap from 3 L straight to 6 L (Imperial or Methuselah), so when you see Rehoboam on a label you are almost certainly looking at Champagne, with the occasional appearance in Burgundy.

Why Champagne Houses Bottle in This Size

Beyond sheer visual drama at the table, the Rehoboam has a technical rationale. In large formats the ratio of wine to the small pocket of air trapped under the cork is more favorable, which slows and evens out oxidation during aging. Champagne held in bigger bottles tends to develop more gracefully, retaining freshness and mousse for longer than the same cuvee in a 750 ml format.

Production is correspondingly limited. Major houses, including LVMH brands such as Dom Perignon, fill Rehoboams largely by hand, often numbering each bottle individually. They are released for prestige cuvees, restaurant programs, and collectors rather than the standard retail lineup, which is why a Rehoboam in a shop or on a wine list usually signals a serious occasion — or a serious cellar.
