How many glasses of wine are in a bottle? A standard 750 ml bottle holds 25.4 fluid ounces and gives 5 glasses at a 5 oz US pour. With UK measures, that is 6 small 125 ml glasses, about 4 standard 175 ml glasses, or 3 large 250 ml glasses.
The number of glasses depends on the pour, not the bottle. Home pours often run larger than restaurant measures, so "two glasses" can be close to half a bottle. This guide shows glasses per bottle size, including half bottles, magnums, and boxes, plus what each bottle contains in units and standard drinks.
How many glasses of wine in a bottle, by pour size?
| Pour | Glasses in a 750 ml bottle |
|---|---|
| 125 ml (UK small) | 6 |
| 5 oz / 148 ml (US standard) | 5 |
| 175 ml (UK standard) | 4.3 |
| 6 oz / 177 ml (US generous) | 4.2 |
| 250 ml (UK large) | 3 |

How many ounces and ml in a bottle of wine?
A standard bottle of wine holds 750 ml, which is 25.4 US fluid ounces, or 75cl on a European label. A half bottle holds 375 ml, or 12.7 oz.
| Format | ml | US fl oz | 5 oz glasses | 175 ml glasses |
|---|---|---|---|---|
| Mini (split) | 187.5 ml | 6.3 oz | 1.3 | 1.1 |
| Half bottle | 375 ml | 12.7 oz | 2.5 | 2.1 |
| 50cl bottle | 500 ml | 16.9 oz | 3.4 | 2.9 |
| Standard bottle | 750 ml | 25.4 oz | 5 | 4.3 |
| Magnum | 1.5 L | 50.7 oz | 10.1 | 8.6 |
| Double magnum or 3 L box | 3 L | 101.4 oz | 20.3 | 17.1 |
The 5 oz column rounds to whole glasses in everyday use, so a magnum is about 10 glasses and a double magnum about 20.
How many glasses of wine in a box?
A typical 3 L box holds the same as four standard bottles, or about 20 glasses at 5 oz. A 1.5 L box holds about 10. Boxes are easy to under-count because you cannot see the level drop, so noting the date you opened one is a useful habit.
How much wine is in a case?
A standard case is 12 bottles of 750 ml, which is 9 litres, or about 60 glasses at 5 oz.
How many glasses of prosecco in a bottle?
A 750 ml bottle of prosecco gives about 6 glasses at a 125 ml flute pour. At 12% ABV, each of those glasses is 1.5 UK units.
How much alcohol is in a bottle of wine?
The glass count is the same at any strength, but the alcohol is not. A "glass" of 14% wine holds more alcohol than the same glass of 11% wine.
| ABV | UK units per 750 ml | US standard drinks per 750 ml | UK units per 175 ml glass |
|---|---|---|---|
| 11% | 8.3 | 4.7 | 1.9 |
| 12% | 9.0 | 5.1 | 2.1 |
| 13% | 9.8 | 5.5 | 2.3 |
| 13.5% | 10.1 | 5.7 | 2.4 |
| 14% | 10.5 | 5.9 | 2.5 |
| 15% | 11.3 | 6.3 | 2.6 |
Two bottles of 13% wine a week is 19.5 UK units, which is above the UK low-risk guideline of 14 units a week. For more detail by strength, see units in a bottle of wine.
The formula for any bottle and pour
Glasses = bottle volume ÷ pour volume
UK units = ml × ABV ÷ 1,000
US standard drinks = fluid ounces × ABV (as a decimal) ÷ 0.6
Example 1: 175 ml glasses from a 750 ml bottle
750 ÷ 175 = 4.3 glasses
Example 2: a 6 oz home pour from a 25.4 oz bottle
25.4 ÷ 6 = 4.2 glasses, not 5
Example 3: US standard drinks in a bottle of 13.5% wine
25.4 × 0.135 = 3.43 oz of pure alcohol, and 3.43 ÷ 0.6 = 5.7 standard drinks
The standard drink calculator and the alcohol units calculator handle any pour and strength.
Why glass counts are easy to get wrong
- Bigger glasses invite bigger pours. A 175 ml pour can look small in a large-bowl glass.
- Top-ups disappear. Refilling a half-empty glass means you never finish a countable "glass".
- Sharing blurs the total. Splitting a bottle between two rarely means an equal split.
- Strength is ignored. Five glasses of 14% wine contain about 17% more alcohol than five of 12%.
Tracking the bottle helps. If you open a 750 ml bottle on Friday and finish it on Sunday, you know the total regardless of how many glasses it felt like. [Alcohol Tracker°](/) lets you log wine by volume and ABV on iPhone and Apple Watch, so the running total reflects what you actually poured.
Glass counts do not measure impairment. Never use them to decide whether you can drive. If you have been drinking, arrange a sober lift, a taxi, or public transport.
