Which champagne bottle size is best for ageing?

The Magnum (1.5 L, equivalent to 2 standard bottles) is the best format for ageing champagne. The Methuselah (6 L) also offers slower, more harmonious ageing.

Should a Jeroboam be served colder than a classic bottle?

No: good champagne should be served between 8 and 13 °C, regardless of the format — bottle, magnum or jeroboam. A larger format simply takes longer to chill: place a jeroboam in the fridge the day before, then keep it in a bucket filled with ice and water during service.

How many flutes can be served from a Rehoboam of champagne?

A Rehoboam of champagne holds 4.5 L, equivalent to 6 standard bottles. It allows you to serve between 30 and 35 flutes. It is a festive format characterised by slow, harmonious maturation.

The essentials

Champagne comes in seven distinct formats: the Quarter (20 cl), the Half (37.5 cl), the Classic (75 cl), the Magnum (1.5 L), the Jeroboam (3 L), the Rehoboam (4.5 L) and the Methuselah (6 L). Each format has specific serving and ageing characteristics, with the Magnum recognised as the best for ageing.

From the Quarter 20 cl to the imposing Methuselah 6 L, champagne formats are not just a matter of capacity: they directly influence ageing.

From the quarter bottle of 20 cl, served as an individual portion, to the 30-litre Melchizedek, which weighs more than a child, champagne comes in a dozen different formats. The most common are the half-bottle, the 75 cl bottle and the magnum; beyond that come the large formats, which champagne houses reserve for celebrations and large gatherings. The table below summarises the capacities, the bottle equivalent and the number of 12.5 cl flutes each format can serve.

Format	Capacity	Bottle equivalent	Number of flutes	Serving temperature	Main characteristics
The Quarter	20 cl	1/4	1.5 to 2	8-13°C	Individual portion
The Half-bottle	37.5 cl	1/2	3 to 4	8-13°C	Ideal for two
The Classic	75 cl	1	5 to 6	8-13°C	Standard, keeps for 3-5 years
The Magnum	1.5 L	2	10 to 12	8-13°C	The best format for ageing
The Jeroboam	3 L	4	20 to 24	8-13°C	Second fermentation in the bottle
The Rehoboam	4.5 L	6	30 to 36	8-13°C	Festive, slow maturation
The Methuselah	6 L	8	40 to 48	8-13°C	Long, harmonious ageing

The magnum: 1.5 litres, the cellar masters' favourite format

A magnum contains 1.5 litres, the equivalent of two bottles, and serves around a dozen flutes. With an identical neck and cork, it holds twice as much wine for the same surface area in contact with the air: the champagne evolves more slowly and keeps its freshness for longer. It is the ideal format for a dinner for six to eight people. Our champagne magnums and jeroboams are grouped together in a single selection, and our guide explains which champagne magnum to choose.

The jeroboam: how many litres?

In Champagne, a jeroboam contains 3 litres, the equivalent of four bottles or two magnums. It serves around 24 flutes of 12.5 cl: enough for an aperitif for twenty people. Note that the name does not refer to the same capacity everywhere: in Bordeaux, a jeroboam contains 5 litres. Like most large formats, it is named after a king of the Old Testament — Jeroboam, the first king of the kingdom of Israel.

A jeroboam requires a little organisation: chill it the day before, lying down, then serve it in a large bucket filled with ice and water. It is served with both hands, the dominant hand under the base of the bottle, pouring slowly. In our cellar, the Deutz Brut Classic jeroboam and the Taittinger Brut Prestige jeroboam make a real impression at the table.

Beyond the jeroboam: the very large formats

After the jeroboam come the rehoboam (4.5 litres, 6 bottles) and the methuselah (6 litres, 8 bottles), followed by bottles rarely seen outside large receptions:

Salmanazar: 9 litres, or 12 bottles;
Balthazar: 12 litres, or 16 bottles;
Nebuchadnezzar: 15 litres, or 20 bottles;
Solomon: 18 litres, or 24 bottles;
Primat: 27 litres, or 36 bottles;
Melchizedek: 30 litres, or 40 bottles.

These very large formats are produced in small quantities by only a few champagne houses, often made to order. For a wedding or a large celebration, several magnums or a jeroboam remain easier to serve and keep cool; our article on how many bottles of champagne for a wedding helps you work out the right quantity.
