Standard Bottle (750 ml)
The default still wine bottle size.
What is Standard Bottle (750 ml)? Standard Bottle (750 ml) is the globally recognized default container for still and sparkling wine, holding 0.75 litres of liquid. It is not merely a convention but a legally defined size, standardized across the European Economic Community in 1975 and adopted in the United States effective 1 January 1979 under 27 CFR Part 4. The format took hold because it fits the practical math of the trade: a 12-bottle case equals exactly 9 litres, and a classic 225-litre Bordeaux barrique yields precisely 300 bottles. For wine professionals and shoppers alike, the 750 ml bottle is the unit by which pricing, tastings, and cellar planning are quoted.
Origin of the Standard
Before metric harmonization, wine moved through international markets in a confusing mix of formats. The European Economic Community settled the question in 1975, fixing 750 ml as a common reference to simplify trade, taxation, and transport between member states. The United States followed shortly after: from 1 January 1979 the 750 ml metric size became the legal standard, while older non-metric formats such as the American 'fifth' (one-fifth of a US gallon, roughly 757 ml) were phased out at the end of 1978.
The choice was pragmatic. At only about seven millilitres less than the old US fifth, the new 750 ml bottle was almost invisible to consumers, yet it slotted neatly into the metric logistics of casks, cases, and pallets. The Bordeaux barrique math — 225 litres divided cleanly into 300 bottles — and the tidy 9-litre case made 750 ml the natural compromise between tradition and modern shipping.
Anatomy and Variants
A 750 ml bottle is more uniform inside than its exterior suggests. The mouth bore is typically 18.5 mm, widening to about 21 mm before opening into the body, which standardizes closures and capsules across producers. Empty weight averages around 500 grams but ranges from roughly 300 to 900 grams depending on glass thickness and style — a sparkling wine bottle, built to contain pressure, sits at the heavy end of that range.
Silhouettes vary by region and carry their own identities. Bordeaux bottles are straight-sided with high shoulders and a pronounced punt; Burgundy and Rhône bottles taper with sloping shoulders and a smaller punt; Champagne bottles are thick-walled, wide, and heavy with a deep punt; Rhine, Mosel, and Alsace bottles are tall, narrow, and have little or no punt at all.
The 750 ml size sits in the middle of a larger family. Smaller TTB-authorized formats include 50, 100, 187, 375, and 500 millilitres, with the 187.5 ml split (or piccolo) and the 375 ml half being the most familiar. Larger formats — 1 L, magnum (1.5 L, equal to two standard bottles), jeroboam (3 L), and progressively grander Bordeaux and Champagne sizes up to the 15-litre Nebuchadnezzar — are reserved for ageing, ceremony, and collectors.
