If you’ve ever caught yourself wondering “How many ounces are there in a bottle of wine?” Or “How big of a pour should I give myself when I’m enjoying a glass at home?” and “How many glasses of wine are in a standard bottle of wine?” We’ve got all the answers you’re looking for!

Wine By the Numbers

The standard 750 ml bottle of wine holds a little more than 25 fluid ounces – which breaks down to five glasses for most wines. This can vary slightly, though, depending on the alcohol content. Wines with a higher alcohol content have a smaller recommended pour, and those with a lower alcohol content have larger pours. 

Some drinks, like port wines, for example, are meant to be enjoyed in small doses. A bottle of port wine can hold as many as 10 glasses! 

There’s more than just one size bottle of wine though! 

Other Wine Bottle Sizes & How Many Ounces They Hold

  • Half – Also known as a demi or split, a half bottle of wine holds 350 ml//12.68 oz
  • Magnum – Double in size to a standard bottle of wine, magnum bottles hold 1.5 L//50 oz
  • Jeroboam – Also known as a double magnum, a jeroboam bottle holds 3 L//101 oz
  • Rehoboam – Just when you thought there couldn’t possibly be a bigger bottle, enter the rehoboam – typically reserved for champagne – which holds 4.5 L//1.52

In order to have the best possible wine tasting experience, though, I highly recommend you have the right glassware! I often joke that I’m not a wine snob. But, I am a self-proclaimed glassware snob. So much so that I’ve even taken my own wine tasting glasses to house parties. Yep, it’s true. But, it just goes to show how much wine glasses actually matter!

In fact, as surprising as it might sound, there is actually a science behind different wine tasting glasses. And, it has everything to do with smell. When you’re using the right glass and the right pour (i.e. – not filling your glass up to the brim after a very long, stressful day), you’ll be able to enjoy those delicious, enhanced aromas. 

Why Knowing How Many Ounces in a Bottle of Wine is Useful

Unfortunately, the United States doesn’t use the metric system like the rest of the world, so you’ll need to remember that 25 ounces is equal to 750 ml of wine. 

And while knowing how to convert milliliters to ounces can help you keep a rough track of how many glasses of wine you’ve had over the course of an evening, in my opinion, there’s better reasons for knowing this metric system conversion. 

“Years, lovers, glasses of wine; these things must not be counted.”

– Anthony Capella

If you have to count glasses of wine, I recommend only doing it in the loosest of terms, strictly for party-planning purposes. Knowing that there’s 25 ounces in a 750 ml bottle of wine can help you make sure you have enough for provisions for everyone and to keep the party going all night long.
