So I just cracked open pic related, but someting is wrong. The beverage feels VERY watered down to me. It is supposed to be 40% but it feels like less than 20%.
>How can I check how much alcohol there actually is?
Two other test subjects said "it is not watered down, fuck off" and "uff this heated me up good", but I don't believe them.

Google calories in 1 serving/30mL of your drink
Perform calorie analysis with burning
The cost to perform this will far exceed the cost of getting another bottle
It's ~70kcal
>calorie analysis with burning
The what now?
it's not so hard, though. OP needs a vacuum flask, a thermometer, and find a way to burn a sample inside.
then you compare change of temperatures from burning of control and test samples
you can also search for "quantitative analysis of alcohols" but then again, cost of performing one exceeds the cost of bottle
>cost exceeds
It doesn't matter, It's for science
I was really hoping I could use something like a sugarmeter and do some math, damn.

Off the top of my head
>determine the weight of the liquid
>determine the volume
>work out the density
>burn the alcohol off
>work out the new weight, volume and density
>determine the difference
Is it really this convoluted?
No easier way?
It's actually easy if you have a distillation apparatus. Boil a sample off at > 100 C to remove everything with a high boiling point, like flavor compounds.
Then cool it down to 85 C. The water will condense, the alcohol will remain a vapor.
Suck off (or let your mom suck off - she's good at it) the vapor, cool the water down to room temperature, and weigh.
>he thinks you can just DO bomb calorimetry and get accurate results
All you need is a measuring jug, scales, saucepan and matches
Gonna try this out with some whiskey. Will report back.
You can stop after the third step, because you can calculate the expected density of a mixture of 60% water and 40% ethanol, from which a bottle of whiskey won't deviate too much. No need to burn anything (which won't even work when the alcohol content is too low).
Ok so I used Brandy instead.
>water
not sure if that's a fair assumption desu
>which won't even work when the alcohol content is too low
You can't bullshit me when I've literally just burned it
I got 35%. Bottle says 36%. I'd call that a success.
step by step pls, I'm not very smart
Well this is all I did
>measure out 100ml of liquid
>put in wok
>heat up
>ignite with matches
>burn
>repeat a couple of times to make sure I got all the alcohol
>measure new volume
>100-new volume = %
Just make sure you switch off the heat before you ignite. I also turned the heat off if it started to simmer to avoid evaporation. Of course you can do it with less liquid but it'll be less accurate. I used measuring spoons to get an accurate volume. Took about 5 minutes.
gonna try it, brb
>Blended Whiskey
This was your own mistake
Educate yourself, faggot
In case its not obvious, only the alcohol on the surface will burn. You need to use a wide pan and stir gently while its burning.
Let me know how you get on.
I'm on it, I think I fucked up already, but It is ok cuz I'm wasted.
The spoon is on fire
That doesn't look like 100ml
I'm using my protein shaker to measure. It is less than 50.
Won't all this burning evaporate a lot of water?
Maybe the pan was too heated up when I poured it in and it evaporated alot. stfu
I think you spread it out too thinly. Mine was about a cm deep in the wok. Oh well.
Mid-experiment 2.0 selfie
nigga use a differant pan
It's 50ml now.
3rd test now in a much smaller container
Don't heat up the pan until after you put it in.
And make sure the heat is off while you're burning it.
What happens if I breathe the vapor? Because I have since I set it on fire.
Did those on 2.0
man, this shit burns 4ever
>burns forever
Alcohol stoves are a thing
On 3.0 It measured 50+
I did fuck around a bit and very well could have evaporated 10ml of water.
Experiments conclusion
-I'm a faggot
-Bushmills is really 40 as advertised
-Blended whisky really doesn't feel as hard as it is, I guess that is the point of it
Anyway thanks everyone that posted.
I enjoyed this thread
>burning liquor below 100 proof
It's bullshit.
Use a hydrometer
/thread
Quick and dirty "smell" test. Put it in a freezer. 40% alcohol will not freeze. 20% will get slushy and lower may freeze solid.
Work out what the density is supposed to be assuming it's only water and alcohol. Weigh a known volume of liquor. Calculate the density and compare to what it's supposed to be. You could also do more math to figure out the percentage.
Density calculation. If you burn it, you will also evaporate some water and other compounds which boil at a low temperature.
>thread filled with images of alcohol burning
>claims its bullshit
pls
Fucking idiots
>Pour the whisky into a cup and measure the depth to which any buoyant object sinks in the whisky
>repeat with alcohol you know to be at 40abv
>compare depths, as buoyant forces are proportional to density you can work out the alcohol content
This is how alcometers work and has the added benefit of not being a fire hazard and being nondestructive meaning you can drink the rest after the test
>other compounds which boil at a low temperature.
such as?
what if the manufacturer substituted oils instead of alcohol, which have similar density
Oils are way more expensive than ethanol, why would anyone do that
