If a beverage contains 60% ethanol, what is its proof?

To determine the proof of an alcoholic beverage, you can use the basic formula that proof is defined as twice the alcohol by volume (ABV) percentage. In this case, if a beverage contains 60% ethanol, you would multiply 60 by 2 to find the proof.

Thus, 60% ABV multiplied by 2 equals 120 proof. This means that the correct choice reflects the standard understanding of how proof is calculated in relation to the concentration of ethanol in the beverage.

Proof is an important measure in the context of alcoholic beverages as it indicates the strength of the drink, which can have implications for consumption guidelines, legal limits, and other regulatory measures. Therefore, a beverage with 60% ethanol is precisely identified as being 120 proof based on the established calculation.
