A litre of 40% ABV spirits per day, or equivalent. It's not that hard.


sort by: page size:

At 40% abv, isn't a drink 1.5 oz?

In which case it's 1280 drinks per year which is 3.5 per day.


> was about 15.76 litres of pure alcohol

I've done the maths on that and it comes out at 39.4 litres of 40% spirits a year, 750ml a week, or 108ml a day. In the UK that is basically two double spirit drinks.

Four UK units a day is above the recommended 14 per week and I'm sure isn't great for your health long term but most people wouldn't notice they are drinking at that level.

I appreciate this is the average so many will be way above that, but interesting to extrapolate it out.


>14.3 litres of pure alcohol a year

To get to this amount of alcohol for reference, a pretty standard bottle of spirits is 750 mL and 80 proof, or 40% alcohol by volume. so if you regularly bought a One liter bottle of liquor you would need to drink 35.75 bottles of Jameson a year, or larger, and pricier, 35.75 bottles of Smirnoff. That is the average, and from public health studies I've read in the past alcohol consumption by average has a serious barbell effect altering the average.

Personally I have three drinks and think " I should slow down"


I make 102g of alcohol about 1 bottle of 14% abv wine (so, strong-ish, but not exceptionally so) per week, or about 3 cans of 10% stout. Unless my math's wrong (1ml ~= 1g [not quite since it's not pure water, but close enough], 750ml * 0.14 = 105ml ~= 105g)

In England medically assisted withdrawal is available if you drink over forty units per day.

One unit is 10 ml pure alcohol. To find the unit qty you multiply the serving size in litres by the alcohol by volume figure.

One litre of spirits at 40% abv is 40 units.


It’s 8 pints of 13% ABV if you look at the table in the article. Manageable over the course of a day, but you’re definitely drinking.

That seems low for "the most hardcore" alcoholics. If we exclude the absolute extreme top 1%, I'd wager the 95th percentile of alcoholics begins at 2 fifths (1.5L) of 40% liquor per day. And I might even be underestimating here.

> It's easy to have a couple of beers or glasses of wine and have 3-4 drinks in the process.

Yes and even drinking that quantity of high ABV beer or large glasses of wine that you describe and you'd still have to do it every day of the week to hit 21 drinks a week.

It is, as suggested upthread, an incredible amount of alcohol to describe with “as little as”.


I might be doing the math wrong, but it doesn't really seem that much:

6 gallons = 768 oz

768 oz 100%abv = 1920 oz 40% abv

1920 oz is approx 192 drinks a year, or 3.7 drinks a week.


It’s one bourbon, one scotch, and one beer per day, swapping for wine on Sundays.

More than I get through, but low for a serious boozer.


> Seems to me that it is okay to have a drink a day

What's one drink?

One 125 ml glass of wine at 8% ABV would be 1 UK unit.

One 175 ml glass of wine at 12% ABV would be 2 UK units, nearly double the alcohol. One of those a day and you're drinking at the UK safe limit levels of 14 units a week.


A bottle of beer (say 500ml) at 5% strength would be 2.5 units, so not as much as 4 bottles a day [1]. Also worth noting that alcohol you buy in shops in the UK has the number of units printed on the label, so it's fairly easy to keep track of.

I don't drink a lot of alcohol, but I make batches of kalja at home for daily consumption - probably 0.5% abv because I'm impatient and bad at it. (And I'm, uh, using bread yeast lol)

It probably averages out to the equivalent of a beer every week or two.


Someone did the calculations. Ppl need to drink 200 gin tonics per day

Okrent had it calculated at equivalent to 7 US gallons of pure ethanol/yr (1830s) to normalize this.

So approx 17.5 gallons at today's standard of 40%. Which is about 2250 standard (1.5oz) drinks a year, or average of 6/day.

There are higher and lower estimates too, but anyway you work the calculations, it's a lot.


People who drink way too much don't drink £55 a bottle spirits. They drink £20 a bottle spirits.

Doesn't it get pretty hard to actually drink it above 40%?

I read an article just recently that argues that the reasonable amount may be much lower than many people think.

http://healthcorrelator.blogspot.com.au/2013/01/how-much-alc...

But there is little variation in one respect. The optimal amount of alcohol is somewhere around 5 and 7 g/d, which translates into about the following every day: half a can of beer, half a glass of wine, or half a “shot” of spirit.


I can't find the thread right now, but someone did a back of the napkin calculation that you'd need to have 200 gin tonics a day to reach any kind of a reasonable level.
