I'm trying to figure out the abv if I add 750ml Everclear(151 proof) to a 1gal mixture with a 1.110 gravity. TIA

MalFet said:It depends on what your final gravity is, but if you know that you can find the abv of your 1 gallon mixture.
From there, it's just:
(750 mL * (151 proof / 200 proof) + 1000 mL * ( ABV of mixture) ) / 1750 mL

If you're not fermenting the concoction any further, I believe the gravity 1.110 gravity doesn't matter. I messed around with some ratios to try and figure it out but my brain hurts now.
Edit: Beaten by Malfet by seconds.

RedOktoberfest said:(volume of A x abv of A, plus vol of B x abv of B ) divided by total vol.
Your FG reading will be garbage. You'll have to assume an FG.
KeyWestBrewing said:The part where I'm getting confused is the 1.110 mixture has no abv since its just a mix of juice and sugar.

No. I think I found the right formula...
(volume of liquor x alcohol by volume/total cocktail volume) x 100
If the formula and my math are correct it should make the new abv ~12.4%
MalFet said:That's basically the same formula Red Oktoberfest and I both posted, but something's fishy in your math.
volume of liquor = 750mL
alcohol by volume = 75.5% (151 proof / 200 proof)
total cocktail volume = 1750 mL (1000mL juice + 750mL everclear)
750 mL * 75.5% abv / 1750mL = 32.4% alcohol by volume
The gravity of your juice is irrelevant if you're not fermenting it. For the purposes of alcohol content, it may as well be water.
NickTheGreat said:I'm kinda asking a question here, but a gravity reading is getting the specific gravity, which is a weight relative to water? Meaning the reading of pure distilled water should be 1.0? So your juicy mix should read something. But you can't correlate that to ABV.
Right? Or is it Friday and my mind is zapped?
I'm assuming that you will let the mix ferment and then add the Everclear. To determine the final ABV you will need to know the ABW of the fermented beverage and its specific gravity. You get the ABW from the balling formula - it's approximately 0.421*(Original_extract - True_extract). There is another formula for apparent extract but I don't remember the multiplier number - will look it up when I'm back home in a couple of days (it depends on OE). From the SG you obtain the density of the fermented 'beer' and, multiplying that by the volume give you its weight. Multiply that by ABW/100. That's the weight of the alcohol. Subtract that from the total to get the weight of the water. The Everclear is 151 proof (75.05% ABW) and so 750 mL contains 0.751*750 mL of ethanol with density 0.789 g/cc which gives the weight of alcohol in the Everclear. You will need to look up (OIML or AOAC tables) the density of a 151 proof solution of ethanol in water to calculate the total weight of the Everclear from which you subtract the weight of the alcohol to get the weight of the water. Now you have the total weight of the alcohol and the total weight of the water from both the Everclear and the fermented beer. From this you can calculate the ABW of the mix ignoring the residual extract of the beer. That's the best you can do as this is a ternary mixture. To get a correct answer you'd have to distill off the alcohol and measure it. Convert ABW to ABV by multiplying by 1.25.
