Quick answer
What sizes do champagne bottles come in?
The standard champagne bottle is 750 ml. The formats sold most are the split or piccolo (187.5 ml), the half bottle (375 ml), the standard bottle, the magnum (1.5 L) and the jeroboam (3 L); larger formats up to the 15 L nebuchadnezzar are made in small quantities. Champagne is bottled at 5–6 bar at 20 °C, so a 750 ml bottle weighs about 830–900 g against 450–550 g for still wine.
| Format | Capacity | Standard bottles |
|---|---|---|
| Split / piccolo | 187.5 ml | 1/4 |
| Half / demi | 375 ml | 1/2 |
| Standard | 750 ml | 1 |
| Magnum | 1.5 L | 2 |
| Jeroboam | 3 L | 4 |
| Methuselah | 6 L | 8 |
Champagne bottles run from the 187.5 ml split to the 15 L nebuchadnezzar, and three of those formats carry nearly all the commercial volume: the 750 ml standard, the 1.5 L magnum and the 375 ml half. Every size has to hold 5–6 bar at 20 °C, which is why a standard bottle weighs 830–900 g against 450–550 g for a still Burgundy or Bordeaux bottle. For a buyer, choosing a format also means choosing a glass weight, a cork length and a cage wire gauge.
Sizes, capacities and glass weights
The format names are borrowed from biblical kings and patriarchs, a marketing habit that goes back to the 19th century. The weights below are planning figures; the drawing for each project confirms the real ones.
| Format | Capacity | Standard bottles | Typical glass weight |
|---|---|---|---|
| Split / Piccolo | 187.5 ml | 1/4 | 400–450 g |
| Half / Demi | 375 ml | 1/2 | 550–600 g |
| Standard | 750 ml | 1 | 830–900 g |
| Magnum | 1.5 L | 2 | 1,600–1,800 g |
| Jeroboam | 3 L | 4 | 2,800–3,200 g |
| Rehoboam | 4.5 L | 6 | ~4,000 g |
| Methuselah | 6 L | 8 | ~5,200 g |
| Salmanazar | 9 L | 12 | ~7,500 g |
| Balthazar | 12 L | 16 | ~10,000 g |
| Nebuchadnezzar | 15 L | 20 | ~12,500 g |
Which formats sell
Beyond the three volume formats, the jeroboam has a steady market in events and showpiece by-the-glass service. Anything above 3 L is a spectacle bottle for hotel openings, club service and auction lots. Those are ordered in hundreds, not hundreds of thousands, and usually sit on an annual call-off contract.
The sourcing route follows from the format and from how far the brand needs to stand apart:
| Route | Where it fits |
|---|---|
| Stock mould (750 ml, magnum) | Any standard programme |
| Modified stock (embossing, colour) | Setting the brand apart |
| Full custom mould | A house cuvée with its own identity |
Large formats inside the Champagne AOC
AOC rules limit which sizes may go through tirage. In practice, bottles bigger than a jeroboam (3 L) are generally filled by decanting from smaller bottles once second fermentation is complete. Prosecco, cava and New World sparkling producers have more freedom. The glass requirement is the same in both cases, because the pressure inside is the same.
Pressure and glass weight
A bottle that sits at 5–6 bar at 20 °C can pass 10 bar if it warms to 40 °C in a container or a warehouse. It has to survive that after rough handling on the filling line, vibration in the case and years in a cellar. The margin is set for the weakest bottle in a batch, not the average one.
The weight of a sparkling bottle is where that margin comes from. The glass goes into thick body walls, a shoulder with a carefully chosen radius (stress gathers at sharp transitions) and a deep, heavy punt that keeps the base from doming outward. A magnum scales the same design up to 1,600–1,800 g. A still-wine bottle has a different glass distribution and base geometry and must never be filled with sparkling wine.
Lightweighting is possible only with evidence. Dropping below tested thresholds risks catastrophic failure in warm storage, so any reduction has to be validated by pressure cycling tests.
Tests to write into the specification
- Proof pressure, ISO 7458. Industry practice, guided by CIVC recommendations and EU pressure-vessel expectations for sparkling wine packaging, is to proof-test to a significant multiple of service pressure. Put both the method and the proof level on the drawing.
- Annealing, ASTM C148. Verified with a polariscope.
- Thermal shock, ISO 7459. Disgorgement lines chill the neck to -25 °C while the body stays warm.
Cork, muselet and finish by format
The closure is an assembly rated for pressure, and each part has to suit both the bottle finish and the format.
- Cork. An agglomerated body, 31–33 mm across before compression, carries one or two natural cork discs on the end that touches the wine. It is squeezed to ~17.5 mm to enter the 17.5–18 mm bore and then swells into the mushroom shape. Large formats take longer corks of 48–54 mm to keep the seal sound.
- Muselet. The wire cage is galvanized steel with four legs that seat under the retaining ring of the finish. Large formats need a heavier gauge. The twist count, typically 6 half-turns, is specified so that the torque needed to open the bottle stays within the safe, familiar range.
- Finish. The 29 mm crown-style sparkling finish also accepts a crown cap for tirage during second fermentation. It has to be gauged closely, since the cage holds only if the ring diameter is right to within a fraction of a millimetre.
We check finish gauges against the cork and cage dimensions of the closure maker you plan to use before a bottle is approved.
Container loading
Sparkling glass reaches a container's weight limit long before it fills the space. Plan on roughly 15,000–17,000 standard champagne bottles, palletized, in a 40HQ, compared with 25,000+ still Burgundy bottles. Our Burgundy bottle guide has the still-wine formats for comparison, and the beer glass bottle collection shows another category where load planning matters.
What to include in an enquiry
- Formats and quantities, from 750 ml up to the large sizes
- The service pressure of the cuvée and any exposure to high temperatures in distribution
- Glass colour and target weight
- The closure plan, including who supplies the cork and muselet
- Destination port and annual volume

Frequently asked questions
Do magnums and larger bottles age champagne differently?
Most cellar masters say yes, and for the better. Cork diameter hardly changes between formats, so a magnum exposes twice the wine to about the same oxygen ingress, and the wine evolves more slowly. Champagne houses generally treat the magnum as the ideal ageing format. Ageing claims for a methuselah and above are disputed among purists, because in the AOC those bottles are typically filled by decanting from standard bottles or magnums.
What is the MOQ for large-format champagne bottles?
It is set per project. The minimum depends on the mould and on the line that runs it.
