How Many Glasses in a Bottle and Other Wine Facts

A standard bottle of wine contains a little over 25 ounces of wine (25.3 oz/0.75L), but how much is that really?

The chart below illustrates the visual relationship to what’s inside a bottle of wine including the number of servings to how many grapes it took to make it.

How Many Glasses in a Bottle of Wine?

The average serving size of 5 oz (150 ml) will give you 5 glasses per bottle.

That said, this number isn’t really exact. It ranges from about 4–6 glasses per bottle depending on the alcohol level. In some cases, such as Port wine where the alcohol level is higher, you can get 10 glasses per bottle!

Fun Fact: In Australia, wines are required to list the number of servings based on the alcohol content. So, a bottle of Shiraz with 15% ABV has 8.9 servings per bottle. In contrast, a bottle of German Riesling with 8% ABV has just 4.7 servings.

  • About 600 bottles are made with a ton of grapes.

How we determined the numbers

number of berries in a bottle of wine:
juice in a grape = 70-80% water + ~7% other dissolved substances in juice = an average of 82% juice.

1.65 lbs (weight of wine) = .82(x)

where x = 0.00385809y and y = number of berries (1.75 grams per berry or 0.00385809 lbs is average, range is ~1 – ~3.5g or 0.00220462 – 0.00771618 lbs)

Range is 300 – 910 grapes per bottle depending on wine grape for example:

550 = Merlot
600 = Chardonnay
910 = Albariño (on average)

bunches in a bottle calculation:

1.65 lbs = .82(.95x)

where x = .375y and y = number of bunches. (.375 lbs per bunch is an average, see sources)
