What type of alcohol is equivalent to one glass of wine?

1. 2 oz of vodka

2. 1.5 oz of 86 proof whiskey

3. 12 oz of beer

4. 4 oz of rum

The correct answer is: 1.5 oz of 86 proof whiskey

The equivalent of one glass of wine, typically around 5 ounces of wine with an alcohol content of about 12-14%, is measured by the amount of pure alcohol it contains. One glass of wine generally contains about 0.6 ounces of alcohol. The correct choice reflects that 1.5 ounces of 86 proof whiskey also contains roughly the same amount of pure alcohol. This is because 86 proof whiskey is approximately 43% alcohol by volume, meaning that 1.5 ounces of whiskey would also deliver around 0.6 ounces of alcohol, making it equivalent in terms of alcohol content to a standard glass of wine. In contrast, the other options have different alcohol volumes that do not match the 0.6 ounces of alcohol found in a glass of wine. For example, 2 ounces of vodka or 4 ounces of rum would contain more alcohol than a glass of wine. Similarly, 12 ounces of beer generally contains less alcohol when compared to a standard glass of wine, making it an inaccurate equivalent. Thus, the choice of 1.5 ounces of 86 proof whiskey aligns perfectly with the alcohol content found in a typical glass of wine.
