What is a
Standard Drink?
It is important to understand what constitutes a “standard drink” to ensure you know how much alcohol you are consuming.
Take a closer look.
One standard drink or serving contains 0.60 oz. of pure ethanol alcohol, which translates to

1.5 oz. of 40% ABV spirits

5 oz. of 12% ABV wine

12 oz. of 5% ABV beer

12 oz. of 5% ABV ready-to-drink cocktail
Alcohol by volume (ABV) is a metric used to determine the alcohol content in beverage alcohol, and it calculates the percentage of a drink's total volume that is pure alcohol.
