What is the alcohol content percentage in 90 proof whiskey?

• A. 40%
• B. 45%
• C. 50%
• D. 55%

Answer: (B)

The correct answer is based on the understanding of how proof and alcohol content are calculated. In the United States, proof is a measure of the strength of an alcoholic beverage, and it is defined as twice the percentage of alcohol by volume (ABV). Therefore, a whiskey that is labeled as 90 proof contains an alcohol content of 45% ABV. This means that if you have 90 proof whiskey, 90 divided by 2 equals 45, indicating that 45% of the beverage is pure alcohol. This principle applies uniformly across all spirits, making it a reliable method for determining the alcohol content based on proof. Understanding the relationship between proof and ABV is essential in the context of substance abuse, as it helps individuals gauge the potency of the beverages they consume and make informed choices regarding alcohol intake.
