Alcoholic units

[MatskiMonk]

Riddle me this...

Drink A: 70cl bottle, 35% ABV. One 25ml shot contains 0.5 units.

Drink B: 70cl bottle, 35% ABV. Bottle contains 25 units.

Are they the same?

 

[DG_Silva]

Kind of. One 70cl bottle contains 28 25ml measures. Also, 1 unit of pure alcohol = 10ml, so it becomes (25{ml} x 35{abv})/1000 = 0.875 units of alcohol per shot. 0.875 x 28{single shot measures} = 24.5.

I suppose if you rounded to the nearest half unit, then yes.

The first bottle is lying apparently. The formula for alcohol units is (mL x ABV number)/1000. So there should be (700*35)/1000 or 24.5 units in there. But seeing as there should be 28 shots in there from 700mL, 28*.5 only comes out to 14 units in the bottle.

I'm glad it's not the consumption of half of bottle A that has affected my mathematics, I thought it didn't add up.

A is made for a supermarket, B is Leggit... hmmmm.

 

[ROAD_DOGG33J]

It could be a misprint or miscalculation, maybe a different formula. How does the taste test check out?

 

[MatskiMonk]

Well, not too bad considering it's half the price, but considering how much I had to drink of it last night, I wasn't nearly as messy as would have expected... hence I checked the label.

Since normally I don't like knock-offs, or massive supermarket chains, I'm going to see where I can go with this!

Bottle A is lying, Bottle B is correct.

Have an orange juice instead? 💡

The issue comes from simplifying the unit content to fit on a label. Because the unit of alcohol per measure is less than 1, they have to round it down to 0.5 per measure.

They could put down .8 or .9, so is this some kind of law? If it is, then it's not a very good one.

Well, it seems as though the mandatory requirement is to be correct to 1 decimal place... which they aren't, but they can get away with only quoting for a 25ml measure as it could be deemed as a 'multi-serve' container. As has been said, according to the labelling, a 70cl bottle of 'Southern Comfort' contains 25 UK units, a bottle of 'Spirit of Louisiana' at the same volume and strength, only contains 14.

I've always said the units system is horse-poo.

I hope it wasn't half price because it was fake. I was watching a TV program last week about illegal vodka production and that stuff is nasty. It can make you go blind due to the wrong type of alcohol being used (should be ethanol but is actually methanol).

I've drank that stuff. It made me rotten ill for 3 days. I was only 15 and thought it was a bargain to get a 75cl bottle of vodka for £5! Turns out it was made with some kind of watered down chemical alcohol. I found that out later watching Watchdog or something like that.

Drink bottle one, record results.
Drink bottle two, record results.
Which ever makes you fall over first is telling the truth.

A.U.?

An astronomical unit (abbreviated as AU, au, a.u., or ua) is a unit of length equal to about 149,597,870.7 kilometres (92,955,807.3 mi)[1] or approximately the mean Earth–Sun distance.

Hmm, so 25ml shot - or - 149,597,870.7km shot....

I certainly do NOT reccomend buying booze that's not legit...
As someone else said the production process is straight nasty, sorta like cigarette knock-offs

No, neither do I but this is just like a 'super-market own brand' it's legit, it's just not very good... kinda like a chinese X5 knock-off.

Southern Comfort is labelled correctly (total units per bottle, rounded up) but the Spirit of Louisiana bottle is completely wrong (units per serving not per bottle, and badly understated).
