Frequently Asked Questions
What is ABV?
ABV (Alcohol By Volume) is the standard measurement of alcohol content in beverages, expressed as a percentage. For example, a beer at 5% ABV contains 5ml of pure alcohol per 100ml of liquid.
What is a standard drink?
A standard drink contains approximately 14 grams (0.6 ounces) of pure alcohol. This is roughly equivalent to 12 oz of regular beer (5% ABV), 5 oz of wine (12% ABV), or 1.5 oz of distilled spirits (40% ABV).
How do I calculate grams of alcohol in a drink?
Multiply the volume in ml by the ABV percentage (as a decimal) by 0.789 (the density of alcohol). For example, a 330ml beer at 5% ABV: 330 × 0.05 × 0.789 = 13.0 grams of pure alcohol.
