HELP!! How do you figure out Proof of alcohol???

post #1 of 12
Thread Starter 
I'm mixing up some limoncello and I want to hit 65 proof. You make this by mixing a lemon extract in grain alcohol into simple sugar. The question is --> Do I ignore the volume change in the simple sugar caused by dissolving the sugar into the water? Do I calculate based solely on the water I added to make the simple sugar or the final volume of the simple sugar???

Continue testing it. When you wake up in a strange place then you know you got the right ingrediants.

32 per cent is 65 proof .. you need to dilute dat stuff

Just use the alcohol/water content.

Grain is 90% (180 proof) so go about 2.8 parts water to 1 part grain, that'll get ya close.

Mike, this is from Wikipedia:





In the definition current in the United States, the proof number is twice the percentage of the alcohol content measured by volume at a temperature of 60 °F (15.5 °C). Therefore "80 proof" is 40% alcohol by volume (most of the other 60% is water), and pure alcohol would be "200 proof". If a 150-proof beverage is mixed half-and-half with water, the product is 75 proof. US proof numbers are properly cited as, for instance, "86 proof," not "86 degrees proof." The use of the word "degrees" in this context is incorrect.


US Federal regulation (CFR 27 5.37 Alcohol Content) requires that liquor labels state the percentage alcohol by volume (sometimes abbreviated ABV). The regulations permit (but do not require) a statement of the proof as long as it is right next to the percentage alcohol by volume. [1]

tee-hee

you're over-thinking it - just use the alcohol percentage in the grain and the volume of the finished limoncello. thats all you need to know - the volume of booze and the total volume.
