The article says a 12 oz beer (slightly larger than the standard 330ml beer) is 1 drink for the purposes of the study.

- opportune 9y ago
  It's actually 0.6 ounces of alcohol irrespective of alcohol content. Therefore 12 oz 5% beer = 1.5 oz 40% liquor = 5 oz 12% wine = 1 unit

I couldn't get beyond the paywall, but did they mention which sort of beer? Standard Bud/Miller products? Using a 12 oz beer as a starting point doesn't mean much in a craft beer world with most "good" beers ranging from 5-8% ABV. Edit: not really understanding the downvotes? Alcohol content is extremely important in understanding the meaning of a "drink". Not trying to be pedantic, but now more than ever, "a beer" is not really a useful descriptor. I bring this up because I personally enjoy a beer at the end of a long day. I tend to drink IPAs, and those IPAs tend to range from 6-8% ABV. Trying to put this article in the context of my personal habits.

    It's 8 grams or 10 mL of pure alcohol. So you would need to calculate that based on percentage and volume for the specific drink. But you can reason using the "standard beer/wine/whiskey units" as a rule of thumb and round up by 1 or 2 total drinks over the course of say a few IPAs vs Budweisers. Same if you drink 100 proof vs 80. Or 15% zinfandel vs 12% merlot.

    A good rule of thumb that my college alcohol edu used was a 12 oz beer, 4 oz glass of wine, and 1.5 oz shot all equaled one drink, at 4,12,and 36% respectively. You'll obviously need to adjust for those numbers but it has always helped anchor me (even though I haven't had a 4% beer since college).

  In the UK we use "units of alcohol". One unit of alcohol is defined as 10 ml of pure alcohol. That's about 8 gm (I think). In the UK the strength of an alcoholic drink is given as Alcohol by Volume, as a percentage. Beer is typically about 5%. To work out the unit you multiply the serving size in liters by the ABV number. A 330 ml bottle of beer at 5% = 0.33 * 5 = 1.65 units. (The bottle would probably say 1.7 units.) The US uses a different amount of alcohol for their standard drink. I think they use 12 gm of pure alcohol. (EDIT: I didn't downvote you. I upvoted you. I don't understand the downvotes.)

  One of my big drinking epiphanies is a US pint of Brooklyn Defender or Ithaca Flower Power IPA is approximately 2 standard drinks. 4 beers in this scenario equals half a fifth of normal 80 proof whiskey like Jack Daniels. A "couple of beers and a shot" becomes equal to an entire bottle of wine. Two beers with a long pour (friendly bartender) of tequila or Jameson on the rocks is again, nearly half a bottle of whiskey. Etc. IPAs are deceptive when you're just trying to "have a couple of beers at the pub down the street after work."

According to the study which was linked in another comment [1] they were using the standard defined in [2]. This site shows that one pint of lager counts as 2 units of alcohol. One pint is 19.2 oz [3]. A bottle of beer is usually 12 oz, aka 5/8 of a pint, aka 1.25 units of alcohol. I trust the source over the science journalist. [1] http://www.bmj.com/content/357/bmj.j2353 http://www.bmj.com/content/357/bmj.j2353 [2] https://www.alcoholconcern.org.uk/unit-calculator https://www.alcoholconcern.org.uk/unit-calculator [3] Google failed me here. British pints are 19.2 oz, not 12 oz, as pointed out in the comments below. On a slightly unrelated note.. A woman would be defined as a moderate drinker if she drinks more than one unit a day, but most beer companies don't sell ~10 oz cans of beer. When I feel like drinking at a restaurant, I make a joke and ask for a "child size" beer. When I drink at home, I usually have to pour out part of the full bottle of beer because it is just too much. It seems like a waste!

  They give a more helpful description within the paper as well. > 1 unit contains 10 mL or 8 g of alcohol > 14 units (UK guidance per week for men and women) is equivalent to 4 pints of high strength beer or 5 large glasses of 14% wine (see below) > 24.5 units (US guidance for men) is equivalent to 7 pints of beer or 9 glasses of wine So 4 pints of high strength beer is 14 "units". 5.2% is the value used, which I wouldn't consider a very high strength beer at all ;)
  - geoelectric 9y ago
    Keep in mind their pint (568ml, per paper) is an imperial pint (19.2 fl oz) and not an American pint (16 fl oz). So, in US terms, UK guidance is ~5 pints and US/men is ~8.5 pints. Not a huge difference in terms of point made, but mostly so the message doesn't get garbled over the pond. Also, their "high strength beer" in the paper (5.2%) is pretty much normal for American lager, so don't get thrown off by the high strength bit.
- Symbiote 9y ago
  One British pint is 568mL, and one "unit" of alcohol is 10mL -- I think the latter might be a European standard. That makes a ½pt (284mL) beer, at 3.5%, almost exactly 10mL of alcohol (284*0.035 = 9.94). The average beer is stronger than it was 20 years ago, but there's still a feeling that 1pt = 2 units in Britain.
oliveshell 9y ago
Right, but beer varies widely in alcohol content. One "standard beer" might be defined as 12 oz / ~330ml @ 4.5% alcohol by volume, but many IPAs are 6-7% or greater, and in most U.S. states you can find lots of beer in excess of 10% ABV.
- frankquestions 9y ago
  “Lots of beer in excess of 10%” is a bit of a stretch. I think it’s more common to see the 6-7% range represented with something pushing 10% being the outlier.

    One of my favorites is Founders Kentucky Breakfast Stout, which is a barrel-aged beer and is around 13%. Actually where I live, barrel-aged beers are becoming very common, most craft breweries have them. And they're all above 10%. Not debating the "specialty concentration techniques" since it's basically infusing the beer with whiskey, but it's certainly very easy to get a beer with an ABV above 10%. Very easy. Your local liquor store likely has several varieties in stock right now.

A bit of a weird and somewhat related trivia to the question of what is a drink there is a reverse situation in Canada sometimes. In Canada (and UK?) legally a pint is 20 fluid ounces but in the USA it's 16 fluid ounces. Some bars in Canada serve 16 oz drinks calling it a pint. My guess is they buy "pint size" glassware from the US but it's 16 oz..
