Math problem...but booze is involved, so it's cool

OK, finished steeping my lemon peels and now need to sweeten and reduce to the correct proof. I've got 1 liter of infused grain which is 190 proof.

 

I need to dilute it to 80 proof, keeping in mind that any water I add has to sweetend by a ratio of 1.50 cups sugar to 1 cup water.

 

I need more coffee....freak.gif

 

 

to recap, 1 liter of alcohol @ 190 proof, needs to be 80%

 

simple syrup is 1.5 cups sugar to 1 cup water.

I'm for the unscientific approach. Get a liter bottle, fill it almost halfway full with the 190 proof stuff. Then finish filling the bottle with pre-mixed sugar water. If you need two liters, do it twice.

Make sure your simple syrup has not one crystal left in it undissolved or it will bloom and ruin your end result. This is the reason most manufacturers use an inverted sugar like High Fructose Corn Syrup.

Oops. You want it to be 80% not, 80 proof.

 

Okay then. 190 proof is 95% alcohol. You want it to be 160 proof (80% alcohol). Add 15% of 1 liter which comes out to be .63 cups of sugar water.

Here are the ratios if you are going from 190 to 80 Proof

1.69 cups of 190 proof

2.32 cups of water

3.48 cups of sugar (due to the addition of 2.32 cups of water)

 

If you're going to use the liter of 190 Proof then add:

5.8 cups of water

8.7 cups of sugar

 

I would say just buy a new bottle of alcohol with a lower Proofcwm27.gif

 

Here are the ratios if you are going from 190 to 160 Proof

3.55 cups of 190 proof

0.67 cups of water

1 cup of sugar (due to the addition of 0.67 cups of water)

 

If you're going to use liter of 190 Proof then add:

0.8 cups of water

1.2 cups of sugar

Patrick, I think your close but the in the best scenario the result would yield 165 proof.

 

1 liter of 190 proof contains .95 liters of alcohol.

If I bring the total volume to 1.15 liters (by adding .63 cups of water alone) then I have .95 liters of alcohol in a total volume of 1.15 liters.

.95 / 1.15 = 0.826 -> 82.6% -> 165 proof

 

However,

.63 cups of sugar water based on KoQ's ratio (1.5 cups sugar to 1 cup of water) would contain 70% sugar and 30% water.

.63 cups sugar water x 30% = .189 actual cups of water

.189 cups of water converts to 0.045 liters.

This would bring the total volume to 1.05 liters rather than 1.15 liters

.95 / 1.05 = 0.905 -> 90.5% -> 181 proof

View PostYeah, you're probably right. It doesn't matter as KOQ ignores me.

 

And in this case he'd be well advised to ignore you, LOL. Look, guys. He said he needs to dilute it to 80 proof, not 80 percent. so he's got to water down 190 proof alcohol to 80 proof alcohol. So to be exact, he needs to add 1.375 liters of non-alcoholic fluid (water and sugar) to his liter of 190 proof booze to make 2.375 liters of 80 proof go juice.

Actually, he said both. First he said he wants it 80 proof. Then he said he wants it to be 80%. 80 proof is 40% alcohol. 80% is 160 proof. Two different numbers.

You're right, Patrick. In his recap I think he got it wrong. I can't imagine him wanting to water it down to 80 percent. Why bother, LOL. 95 percent is close enough. 80 proof is about where something you're going to drink straight up needs to be. I drank 3/4 of a fifth of Bacardi 151 one night soon after arriving in Germany and that kind of juice is a little too hot to recommend. I've stayed well clear of that stuff ever since.

Make a three cup volume of the sugar / water solution (about 710 mLs).

 

C1*V1 = C2*V2

 

190 proof * X = 80 proof * 1000 mLs

 

X = 421 mLs

 

Take 421 mLs of alcohol and dilute to 1 liter with the sugar water (579 mLs).

 

You might waste a little sugar water but this could be the easiest way.
