A standard wine bottle holds 750 ml (about 25.4 fl oz). If you make your own wine, the number you really need is how many of those bottles a batch will fill, so enter your batch size below and the calculator does the rest.
It works in US gallons or liters, lets you pick the bottle size, and subtracts a headspace and sediment allowance that you can change. It also tells you how many glasses each bottle pours. Buying bottles is a separate question, covered in our guide to wine bottles for homemade wine.

How Many ml in a Bottle of Wine
A standard bottle of wine is 750 milliliters, which is 0.75 liters or about 25.4 US fluid ounces. The conversion is simple: one US fluid ounce is 29.57 ml, so 750 divided by 29.57 gives 25.4. The bottle is also three quarters of a liter, which is why four standard bottles equal one 3 liter bottle.
Why 750 ml
It is one of the sizes the US rules list as a standard of fill for wine. The Alcohol and Tobacco Tax and Trade Bureau (TTB) sets the authorized sizes in 27 CFR 4.72, and 750 milliliters is on that list, alongside 1 liter, 500 milliliters and 375 milliliters among others. Your own bottles do not have to follow these rules, but matching them means any standard bottle and cork will fit.
Quick conversions
A 750 ml bottle holds 0.198 US gallons. In the other direction, one US gallon is 3.785 liters, so a gallon batch is about 5 bottles before you lose anything to sediment. The calculator uses a 5 percent allowance for that loss, and you can set it to zero if you want the raw volume.
Wine Bottle Sizes
The sizes below are the ones you are most likely to meet when you bottle at home. The names come from the Wikipedia article on wine bottles, and the volumes agree with the TTB list of authorized standards of fill, which includes 187 ml, 375 ml, 500 ml, 750 ml, 1 liter, 1.5 liters and 3 liters (27 CFR 4.72).
| Bottle | Common name | Volume | US fl oz | Standard bottles |
|---|---|---|---|---|
| Single serve | Piccolo or split | 187 ml | 6.3 | 0.25 |
| Half bottle | Demi | 375 ml | 12.7 | 0.5 |
| 500 ml | No common name | 500 ml | 16.9 | 0.67 |
| Standard | Standard | 750 ml | 25.4 | 1 |
| Liter | Liter | 1,000 ml | 33.8 | 1.33 |
| Magnum | Magnum | 1,500 ml | 50.7 | 2 |
| Double magnum | Double magnum or jeroboam | 3,000 ml | 101.5 | 4 |
The fluid ounce and bottle-equivalent columns are computed with 29.57 ml per fl oz and 750 ml per standard bottle.
What are magnum bottles
A magnum is a 1.5 liter bottle, the same as two standard bottles. It is popular for gifts and for wine you plan to age, but it needs a cork and corker that suit the bigger bottle and a batch large enough to fill it.
Which size to choose for homemade wine
Most home winemakers use 750 ml bottles because they are easy to find, take standard corks and pour about five glasses. Half bottles are handy for sweet wines you serve in small pours. Our guide to how to bottle and cork wine covers the corks and the filling.
How Many Glasses in a Bottle of Wine
A 750 ml bottle pours about five standard glasses. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) describes a standard drink of table wine as a 5 ounce glass at 12 percent alcohol by volume. Five fluid ounces is 148 ml, and 750 divided by 148 is 5.07, so a bottle gives you five full pours with a small splash left over.
Glasses for other pour sizes
Restaurants and home hosts often pour smaller or larger than five ounces. The table uses the same math (750 ml divided by the pour in ml).
| Pour | ml | Glasses per 750 ml bottle |
|---|---|---|
| 3 fl oz (tasting) | 89 | 8.5 |
| 4 fl oz | 118 | 6.3 |
| 5 fl oz (standard) | 148 | 5.1 |
| 6 fl oz | 177 | 4.2 |
| 8 fl oz (large) | 237 | 3.2 |
A note on strength
The NIAAA serving assumes 12 percent alcohol. A homemade wine at 14 percent has more alcohol in the same glass, so if you are counting drinks, a five ounce pour counts for more than one. You can measure your own figure with our wine ABV calculator.
Bottles per Batch
Multiply your gallons by 3.785 to get liters, then divide by 0.75. A 1 gallon batch is 3.785 liters, which is 5.05 bottles with no loss, and a 5 gallon batch is 18.925 liters, or 25.2 bottles. In practice you rarely fill all of them, because the lees stay behind when you rack the wine and each bottle needs headspace under the cork.
Realistic yields
With the default 5 percent allowance the calculator gives these results for 750 ml bottles.
| Batch | No loss | 5% allowance |
|---|---|---|
| 1 gallon | 5 bottles | 4 bottles |
| 3 gallons | 15 bottles | 14 bottles |
| 5 gallons | 25 bottles | 23 bottles |
| 6 gallons | 30 bottles | 28 bottles |
The calculator rounds down because a part bottle is not a bottle you can cork and store. That leftover is the wine you taste while you bottle.
The 5 percent is an estimate
We use 5 percent as a starting point for the sediment you leave behind when you rack and for the wine that stays in the siphon. It is not a measured figure, so change it to match your own batches. If you rack carefully, use less. If your wine threw a heavy lees, use more. Our guide to how to rack wine shows where the loss comes from.
Planning Bottling Day
Work out your numbers a few days before, not on the day. The calculator tells you how many bottles to wash and sanitize, and it takes the surprise out of a last bottle that is only half full.
Count bottles, corks and a spare
Plan one cork per bottle plus a few spare, since a bad cork costs less than a spoiled bottle. Bottles are often sold by the case of 12, so a 5 gallon batch needs two cases and a few more. The items in the box below are the ones this job calls for.
Leave room in each bottle
Fill so the wine sits just under the cork with a small air gap, not to the lip. The gap is one reason a bottle never holds exactly 750 ml of wine, and one more reason to keep the allowance in the calculator.
Label and store
Write the date, the wine and the batch on each bottle. Once you know how many you have, our guide on how long homemade wine lasts helps you decide how fast to drink them.
What you need for bottling day
Bottles, corks and a corker are the three items that decide how smoothly the job goes.
