How Many Glasses in a Bottle and Other Wine Facts

How many glasses in a bottle of wine? 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.

A bottle of wine contains 5 servings of wine (at 5 oz / 150 ml)

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!

What’s Inside a Bottle of Wine

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.

How we came up with the numbers

To determine 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 grapes in a bottle of Merlot
• 600 grapes in a bottle of Chardonnay
• 910 grapes in a bottle of Albariño (on average)

To determine grape bunches in a bottle:

1.65 lbs (weight of wine) = .82(.95x)

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