Thinking about the alcohol in a bottle of wine is a great way to better understand what you're drinking. The truth is, there isn't one single answer, as the exact amount of alcohol depends entirely on the specific wine you choose. The key to unlocking this information is right on the label: the Alcohol By Volume, or ABV.
The ABV percentage tells you exactly what portion of the bottle's content is pure alcohol. For a standard 750ml bottle of wine, you can figure out the pure alcohol content with a simple calculation. You just multiply the volume of the bottle (750ml) by the ABV. For example, if you have a wine with a 12% ABV, the calculation is 750 times 0.12, which equals 90ml of pure alcohol in that bottle.
This is where it gets interesting, because wines vary quite a bit. A light-bodied white wine might have an ABV of 11%, giving you 82.5ml of alcohol. On the other hand, a bold, full-bodied red like a Zinfandel could have an ABV of 15%, which means it contains 112.5ml of alcohol. That’s a significant difference from the same-sized bottle.
This is also why a bottle of wine contains a varying number of "standard drinks." A typical bottle with an average ABV of around 12.5% contains about 5 standard servings of alcohol. However, a higher-alcohol wine will contain more. By simply checking the ABV on the label, you empower yourself to make a more informed choice and truly understand the character and strength of the wine you're enjoying.
