  • A standard drink is a measure of alcohol. In Ireland, one standard drink contains 10 grams of pure alcohol.
  • The HSE low-risk weekly guidelines are no more than 11 standard drinks for women and no more than 17 for men, these should be spread out throughout the week, with at least 2 alcohol-free days.
  • The number of standard drinks is based on the size of the drink and its alcohol strength, usually shown on labels as alcohol by volume (%ABV). The higher the alcohol strength, the higher the standard drink content.
  • It takes your body at least one hour to process one standard drink.
  • For reference: a pint = 568mls & a pub measure of spirits = 35.5mls.
