A standard bottle of wine contains a little over 25 ounces of wine, but how much is that really? This chart shows a visual relationship to what’s inside a bottle of wine from the number of servings to how many grapes were crushed to make it. Get to know wine on a fundamental level.

## How Many Glasses in a Bottle of Wine?

5 glasses

This number isn’t exact. Glass serving size actually ranges quite a bit, from about 3-6 ounces, because wines range in alcohol level from 5.5% – 21% ABV.

In Australia, wines are required to list the number of servings based on the alcohol content. For example, a bottle of Shiraz would have 8.9 servings and a bottle of German Riesling would have 4.7 servings. The Consumer’s Federation of Australia also proposed replacing all restaurant glassware with a single standard glass and an etched fill line. Not cool.

How we determined the numbers

amount 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)
