How Many Ounces In a Bottle of Wine? (750ml Bottle & Every Size in Oz)

It seems an obvious enough question to answer, but how many ounces are in a bottle of wine can be a tricky one, especially if your brain works in millilitres. 

So let's look at converting imperial to and from metric using wine as a handy example. If only all maths equations looked like this!

How Many Ounces In a Bottle of Wine

A standard bottle of wine is 25.4 fluid ounces or 25.4 oz per 0.75L.

But the maths gets a little trickier when you take wine glasses into account.

Wine glasses come in lots of different shapes and sizes, so how can you tell how many fluid ounces will make up one glass of wine?

Here's a table of all the measures of wine sizes in ounces:

Standard Wine Bottle (750ml)

• 25.4 ounces

Standard Wine Glass (125ml)

• 4.4 ounces

Medium Wine Glass (175ml)

• 6.1 ounces

Large Wine Glass (250ml)

• 8.8 ounces

Low Alcohol Wine (per serving)

• 6-11 ounces

High Alcohol Wine (per glass)

• 4.5-5 ounces

Sparkling Wine (per glass)

• 4.5-5 ounces

Dessert Wine (per glass)

• About 3 ounces

Fortified Wine (per glass)

• 1.5-2 ounces

Half Bottle (375ml)

• Just under 13 ounces

Magnum (1.5 liters)

• 51 ounces

Jeroboam (3 liters)

• 102 ounces

How Many Ounces In a Glass of Wine?

Here's how many ounces different sizes of glass weigh in ounces:

Standard Wine Glass

A standard wine glass is 125ml and this works out as 4.4 oz of wine.

Medium Wine Glass 

A medium glass of wine, that unusually comes in at 175ml, will therefore be 6.1 oz of wine.

Large Wine Glass

And then, last but not least, a large 250ml glass of wine will hold around 8.8 oz of wine instead. 

Now this is all well and good but does the style of wine affect the standard pour in ounces?

Should different styles of wine be served in different quantities?

Standard Wine Pour in Ounces Based on the Wine Style

Here’s a handy guide to how many ounces of wine you should be aiming to pour depending on the style of wine you are drinking:

Low Alcohol Wine

Lighter styles of wine such as Beaujolais or Vinho Verde can be served in larger quantities and you can pour between 6-11 ounces of wine per serving

High Alcohol Wine

Bolder, fuller bodied wines such as Cabernet Sauvignon and Zinfandel are best served in smaller portions, so aim for around 4.5-5 ounces of wine per glass.

Sparkling Wine

Fizzy and fun styles of wine like Champagne and Prosecco can be served in smaller quantities to help keep the sparkle in the glass fresh. Aim for around 4.5-5 ounces.

Dessert Wine

Decadently sweet styles of wine like Sauternes and Tokaji can be served even smaller still. Aim for about 3 ounces of wine per glass, and remember you can always go back for another glass when you’re done

Fortified Wine

Rich and complex, fortified wines such as Port and Sherry are best served in small glasses, try about 1.5-2 ounces of wine per glass for these styles. 

So that’s a good introduction to ounces of wine and all the sizes they can come in, but why is it useful to know this information in the first place?

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