False. There’s no single standard drink size across the world. While a standard unit in the UK contains eight grams of ethanol. In practice, this translates into a small glass of wine (125 ml), a pint of beer, or 25ml of spirits. Different countries use different definitions. However, within each country, a ‘standard’ unit is the same for a serving of beer, wine or spirits. The concept of a standard unit is important. It is roughly the amount of alcohol the body can process in an hour and helps consumers understand how much alcohol they are drinking.
