How Many Glasses of Wine Are in a Bottle?
It sounds like a simple question, but the answer is surprisingly useful.
Whether you're planning dinner for a few friends, figuring out how many bottles to buy for a party, or just wondering how far one bottle should go, knowing how many glasses are in a bottle makes wine planning much easier.
Fortunately, the math is simple.
The Simple Answer: About 5 Glasses
A standard bottle of wine contains 750 milliliters, or a little over 25 ounces.
A standard wine serving is generally considered 5 ounces.
That means one standard bottle gives you approximately:
5 glasses of wine
That's the number I would use for almost any planning situation.
Of course, real-life pours aren't always exactly five ounces.
Why You Might Get 4—or 6—Glasses Instead
Pour generously at home and you might only get four glasses from a bottle.
Use slightly smaller pours and you could get six.
The size and shape of the wine glass can also make a pour look smaller or larger than it actually is. A five-ounce pour in a large wine glass can look surprisingly modest.
That's one reason it's easy to pour more wine than you realize.
But you don't need to measure every glass.
For planning purposes, just remember:
1 bottle = about 5 glasses.
How Many People Does One Bottle Serve?
That depends on how much everyone is drinking.
If everyone is having one glass, one bottle can serve about five people.
If you're planning on two glasses per person, one bottle is closer to enough for two or three people.
For a dinner with four wine drinkers, for example, I'd generally plan on two bottles if wine is being served throughout the meal.
You may not finish both, but you won't have to worry about running out halfway through dinner.
How Many Bottles Do You Need for a Party?
This is where the five-glass rule becomes especially useful.
If you expect your guests to drink 20 glasses of wine:
20 glasses ÷ 5 glasses per bottle = 4 bottles
Then give yourself a little flexibility based on the crowd and what else you're serving.
If wine is the main alcoholic drink, you'll probably want more.
If you're also serving beer and cocktails, you'll probably need less.

What About Sparkling Wine?
A standard bottle of Champagne, Prosecco or other sparkling wine is also generally 750 mL.
But sparkling wine is often served in slightly smaller portions, especially for a toast.
That means you can sometimes get 6 glasses or more from one bottle.
If you're simply pouring sparkling wine as you would any other wine, however, using the five-glass rule is still a safe and easy estimate.
What About Larger Bottles?
The same basic math applies.
A magnum contains 1.5 liters—the equivalent of two standard bottles—so you'll get roughly 10 standard glasses.
And while larger-format bottles can be fun for celebrations, there's no need to buy them just to make serving easier. Standard 750 mL bottles are perfectly fine for almost every occasion.
Don't Overthink the Pour
Wine doesn't need to be measured with a jigger every time you open a bottle.
The five-ounce serving is simply a useful reference point.
At home, pour an amount that feels comfortable and leaves enough room in the glass to swirl the wine.
If your pours are a little larger or smaller, that's completely normal.
The important thing is knowing that when you're buying wine for dinner or a gathering, five glasses per bottle gives you an easy number to work with.
Final Sip
A standard 750 mL bottle of wine gives you approximately five 5-ounce glasses.
That's really the number worth remembering.
Once you know it, figuring out how many bottles you need for dinner, a party or a special occasion becomes much easier—and you can spend less time doing math and more time enjoying the wine.
