What is the standard drink size for Sauvignon Blanc?

• A. 208 mL
• B. 90 mL
• C. 101 mL
• D. 570 mL

Answer: (C)

The concept being tested is how a standard drink is defined for different beverages. A standard drink represents a fixed amount of alcohol, set so you can compare how much alcohol you’re consuming across drinks. For wine like Sauvignon Blanc, the standard drink size is about 100 mL, because wine typically has around 12–13% alcohol by volume. At that ABV, about 100 mL of wine contains roughly 10 g of ethanol, which is the standard amount used in guidelines.

So 101 mL is essentially the closest match to the standard drink size for Sauvignon Blanc. The other options are noticeably larger or smaller than one standard drink—208 mL would be more than one standard drink, 570 mL is several, and 90 mL is a bit under one standard drink.
