How Many Ounces Are in a Bottle of Wine?
25.36 fl oz
A 750 ml bottle of wine holds 25.36 fluid ounces. The NIAAA calls this size a regular wine bottle, and it is one of the US standards of fill for wine in 27 CFR 4.72.
In UK (imperial) fluid ounces, the same bottle holds 26.4 imp fl oz.
Wine bottle sizes in ounces
| Bottle size | US fl oz | Pours of 5 fl oz |
|---|---|---|
| 187 ml, about a quarter of a regular bottle | 6.32 | 1.3 |
| 375 ml, half a regular bottle | 12.68 | 2.5 |
| 750 ml, a regular bottle | 25.36 | 5.1 |
| 1.5 L, two regular bottles | 50.72 | 10.1 |
| 3 L, four regular bottles | 101.44 | 20.3 |
Is every wine bottle 750 ml?
No. US rules allow many wine container sizes, called standards of fill, and 750 ml is only one of them. The list in 27 CFR 4.72 includes 187 ml, 375 ml, 1.5 L and 3 L bottles, among others.
Above 3 L, wine can be packed in containers of 4 L or more, as long as they are filled in whole liters. The TTB added 13 more wine sizes in a rule published in January 2025.
Two of those sizes relate simply to the regular bottle. A 375 ml bottle holds half as much, 12.68 fl oz, and a 1.5 L bottle holds twice as much.
How many glasses are in a bottle of wine?
About 5, if you pour standard drinks. In the US, one standard drink of table wine, which is about 12% alcohol, is 5 fl oz, according to the NIAAA. The CDC uses the same 5 fl oz figure for wine with 12% alcohol.
A 750 ml bottle holds 5.07 pours of that size, which the NIAAA rounds to 5 standard drinks. Bigger pours empty the bottle faster, as the table below shows.
| Pour size | Glasses per bottle |
|---|---|
| 5 fl oz (US standard drink) | 5.1 |
| 6 fl oz | 4.2 |
| 8 fl oz | 3.2 |
| 125 ml (UK legal measure) | 6 |
| 175 ml (UK legal measure) | 4.3 |
How is wine measured in the UK?
UK law sets the glass sizes. Wine sold by the glass must come in 125 ml or 175 ml measures, or in multiples of those, under the Weights and Measures (Intoxicating Liquor) Order 1988.
A 750 ml bottle fills exactly 6 glasses of 125 ml, or about 4.3 glasses of 175 ml.
The same order lists set sizes for pre-packed still wine. They include 568 ml, about one imperial pint, as well as 750 ml, according to schedule A1.
How to measure a standard glass of wine
Find the line in your own glass with water first. A pour of 5 fl oz is 148 ml, or 5/8 cup in a liquid measuring cup.
No measuring cup? Use a tablespoon: 5 fl oz equals 10 tablespoons. Note where the water sits in the glass, then pour wine to the same level.
Bottle of wine: questions
Is a glass of wine 5, 6 or 8 oz?
The US standard drink of wine is 5 fl oz, as defined by the NIAAA and the CDC. A 6 fl oz or 8 fl oz glass holds more than one standard drink: about 1.2 or 1.6 of them, for wine with 12% alcohol.
Is a bottle of wine 24 or 26 ounces?
Neither. A regular 750 ml bottle holds 25.36 fl oz in US fluid ounces, between the two. In UK (imperial) fluid ounces, the same bottle is 26.4 imp fl oz.
Do 4 glasses of wine equal a bottle?
Only if each glass holds about 6.3 fl oz. That is the size of the small 187 ml bottle, and a regular bottle holds 4 of those. With standard pours of 5 fl oz, a bottle gives about 5.
Is 12 oz two glasses of wine?
A little more than two standard glasses: 12 fl oz is 2.4 pours of 5 fl oz. It is also about 2 UK glasses of 175 ml, and just under half of a regular bottle.
