What is the standard drink equivalence used in RBS training?

• A. 12 oz beer (about 5% ABV), 5 oz wine (about 12% ABV), or 1.5 oz of 80-proof distilled spirits (about 40% ABV)
• B. 16 oz beer, 6 oz wine, or 2 oz spirits
• C. 8 oz beer, 4 oz wine, 1 oz spirits
• D. 20 oz beer, 10 oz wine, 3 oz spirits

Answer: (A)

In RBS training, the idea is to compare how much alcohol is in different drinks using a standard reference amount. A standard drink in the US contains about 14 grams of pure alcohol, which is roughly 0.6 fluid ounces. That amount is found in typical servings like 12-ounce beer at about 5% ABV, 5-ounce wine at about 12% ABV, or 1.5 ounces of 80-proof distilled spirits (40% ABV). So the option shown is correct because each of those servings, despite being different beverages, delivers about the same amount of pure alcohol.

Other options don’t match this standard because their listed servings would contain more or less than one standard drink, meaning they don’t reflect the same amount of alcohol as the standard reference. Understanding this helps you estimate total intake and make informed service decisions in real-world settings.
