What is the standard drink size of Light Strength Beer?

• A. 469 mL
• B. 268 mL
• C. 34 mL
• D. 313 mL

Answer: (A)

A standard drink is the amount of alcohol that equals about 10 grams of ethanol. To work this out, use grams of ethanol = volume in mL × ABV% × 0.789 / 100. Set that equal to 10 g and solve for volume. If Light Strength Beer is about 2.7% ABV, the needed volume is roughly 10 × 100 / (2.7 × 0.789) ≈ 469 mL. So the standard drink size for this beer is about 469 mL. The other options would not reach 10 g of ethanol at this lower strength, or would require a much stronger beer to reach a standard drink.
