How many bottles in a case of wine?
Quick answer
A standard case of wine contains 12 bottles of 750 ml, totalling 9 litres. This convention dates back to 19th-century maritime trade, where 12 bottles roughly equalled 2 imperial gallons — the dominant British unit of measure at the time.
Detailed answer
Twelve bottles to a case — it's one of those wine conventions everyone takes for granted, but it has a surprisingly logical origin.
The most widely accepted explanation goes back to 19th-century trade between France and Britain. The British imperial gallon equals about 4.546 litres. Two gallons (9.09 litres) is almost exactly 12 bottles of 750 ml (9 litres). So when Bordeaux merchants shipped wine to London, a case of 12 made the customs arithmetic easy.
Practicality sealed the deal: a case of 12 weighs about 16–18 kg (35–40 lbs) — heavy but manageable for one person to carry. And 12 divides neatly by 2, 3, 4, and 6, making it easy to split, price, and sell.
Variations exist: cases of 6 are common for premium wines, magnums, and prestige Champagne. Some Burgundy estates sell mixed cases of 12, with 2 bottles each of 6 different wines — a great way to explore a producer's range.
Buying by the case almost always saves money. Most retailers and online shops offer a 5–15 % discount for full-case purchases. If you find a wine you love, buying 12 at once is usually the smartest move.
Original wooden cases ("OWC" in auction language) are especially valued by collectors. A wine stored in its original wooden case from a reputable château can command a premium at auction, because the provenance is easier to verify.
