ServSafe Alcohol Practice Exam

Which of the following combinations constitutes one standard drink?

1. 1 shot of 80 proof vodka

2. 1 ounce of 100 proof whiskey

3. 5 ounces of wine

4. All of the above

The correct answer is: All of the above

One standard drink is defined by the amount of pure alcohol it contains, typically around 14 grams (0.6 ounces). A shot of 80 proof vodka, which is 40% alcohol by volume, typically contains about 1.5 ounces, equating to roughly 0.6 ounces of pure alcohol. Therefore, it qualifies as one standard drink. One ounce of 100 proof whiskey contains 50% alcohol, which means that a 1-ounce serving contains 0.5 ounces of pure alcohol. While this is slightly less than the 0.6 ounces of alcohol in a standard drink, it is important to recognize that this amount can vary depending on the context or specific serving sizes. A standard serving of wine is 5 ounces, which generally contains about 12% alcohol by volume, equating to roughly 0.6 ounces of pure alcohol, thus also qualifying as one standard drink. Understanding these values is crucial because they help both consumers and servers recognize what constitutes responsible drinking and how to manage alcohol service effectively. In this case, all these combinations fit the general definition, making the provided answer correct.
