So.... the blending calculator. I have never been able to get this to work. Never, ever, ever. I enter the known ABVs (17, 0), I enter the known volume of #1 (5), I enter the desired ABV (12), and click on Volume #2..... and nothing happens. Even changing ABV 2 to a non-zero number has no affect.
You need 4 bits of info to find the 5th.
eg,
So if you have 5 gals of 17 ABV and are blending it with a known volume of say 2 gals of 12 ABV and want to know the resultant abv,
then
enter value1=17, Value2=12, Volume1=5 and volume2=2 and click the button for blended value (15.571 ABV is the resultant ABV)
Or,
If you have 5 gals of 17 ABV and are blending it with a 12 ABV quantity to achieve 13 ABV and want to know how much 12ABV volume to add,
then
enter value1=17, Value2=12, Volume1=5 and BlendedValue=13 and click the button for Volume2, which tells you you need 20 gallons of 12 ABV to blend
