Wine Bottle Sizes, From Split to Nebuchadnezzar

Wine bottles come in more than a dozen sizes, and the big ones carry the names of Babylonian kings. Here is the complete list, from the smallest single-serve split to the 15-liter Nebuchadnezzar, with volumes and standard-bottle equivalents for each.

The complete size chart

• Split (Piccolo), 187.5 ml: A quarter bottle, one generous glass. The airline and mini-bar format, and standard for single-serve sparkling.
• Half bottle (Demi), 375 ml: Half a standard bottle, about 2.5 glasses. Popular for dessert wines and restaurant lists.
• Standard, 750 ml: The world's reference bottle, about 5 glasses. Every other format is measured against it.
• Magnum, 1.5 L (2 bottles): The collector's favorite. Slower, more graceful aging thanks to the lower oxygen-to-wine ratio.
• Double Magnum / Jeroboam, 3 L (4 bottles): Called Double Magnum in Bordeaux and Jeroboam in Champagne, the first of the naming confusion.
• Rehoboam, 4.5 L (6 bottles): Mostly seen in Champagne. Named after the son of Solomon.
• Imperial / Methuselah, 6 L (8 bottles): Imperial in Bordeaux, Methuselah in Champagne, same volume, two names.
• Salmanazar, 9 L (12 bottles): A full case in a single bottle.
• Balthazar, 12 L (16 bottles): Named for one of the three Magi.
• Nebuchadnezzar, 15 L (20 bottles): The Babylonian king, and usually the largest format produced commercially. Larger novelties exist (Melchior at 18 L, Midas at 30 L) but are vanishingly rare.

Why the biblical names?

Nobody knows for certain. The convention emerged in Champagne in the 19th century, most likely as marketing theater: naming your biggest bottles after ancient kings makes them feel monumental. The names stuck, spread to Bordeaux with slight differences, and have confused sommeliers ever since.

Large formats age differently, and that matters

The wine-to-oxygen ratio changes with bottle size. Every bottle admits a tiny amount of oxygen through the closure, but a magnum holds twice the wine behind roughly the same cork surface, so the wine oxidizes more slowly and ages longer and more gracefully. This is why magnums command more than double the price of two standard bottles at auction, and why halves mature noticeably faster.

What producers should actually stock

For a small winery, every format beyond 750 ml is a separate SKU with its own glass, corks, capsules, labels, and cartons. The practical lineup for most producers: standard bottles for volume, magnums for flagship wines and gifting (they sell at a premium and mature beautifully), and halves only if your restaurant channel asks for them. Each format you add roughly doubles the dry-goods lines you have to count, order, and store.

That multiplication is exactly where inventory systems earn their keep: in Oenova, each format is its own tracked SKU, bottling runs deduct the right glass and closures per format, and you can see at a glance that you have 40 cases of standard and 18 magnums of the same wine across two warehouses.
