What is the standard drink size of Red Wine (mL)?

Explanation:
The standard drink is defined as about 10 grams of alcohol. To relate this to red wine, use that a typical red wine is around 14% alcohol by volume (ABV). One standard drink contains roughly 12.7 milliliters of pure ethanol (10 g ÷ 0.789 g/mL). If wine is 14% ABV, the volume of wine needed to get 12.7 mL of ethanol is 12.7 ÷ 0.14 ≈ 90 mL. So about 90 mL of red wine at that ABV delivers one standard drink. The other options would give too little or too much ethanol for a single standard drink at this ABV.
