Rob,
Thank you but I want a little more, or am I not reading them right. I want to know how to mix several different %'s to acheive a certain finished %.

James:

Could you be more specific. Percentages of what exactly are you looking for? Do you mean mixing a rum with a percentage of 87 and a vodka with a percentage of 95? Or you looking for what percentages you can expect from certain grains?

Elricko,
I have been getting 85% mid runs with tails to about 58 before I would not use it.
I would like to mathmatically figure out how much 85,70, and 62 to use to make 40%

James, Ditto Elricko, I am thinking you have several different cuts or seperate distillations of differing %? And if so, how to mix all together to a final ABV? I may be all wrong, but have been here myself. If thats the case, easy answer, I just ask Elricko.

But first mix all together, check ABV and then proceed.

I think he deserves a drink!

John,
Why mix all together.
I like having several levels of %.

OK, thats a total new equation. I still would mix it all together to average and anneal flavors, and at the highest % the yield mixes. You could then easily cut to whatever % you wanted. You do have an alkometer? I couldn't function without one. cut each to strength and enjoy.

John,
Thanks alot.
I guess that makes sense for the flavor thing.
I keep a close eye on temp. and collect in pints when temp rises over 78

Jim:

I agree with John. That is how I would do it, however that doesn't answer your question. To figure out how to get to where you want to be you need to figure out where you are. Say you have three pints, one with 58%, the second with 75%, and the third with 36%. You want to add them together and make them all 40%.

Attached is a simple spreadsheet calculator to help figure this out.

As you can see, I took each pint and broke it down to ounces then figured out how many oz of ethanol and how many oz of other liquids are in each pint. With this little calculator, as you add water to the 'Added H2o' column your total liquid increases but your % of Alcohol reduces. This way you should have pretty good idea about how many oz of distilled water to add to get your desired 40%
UserPostedImage
In this case you would need to add 19.6 Oz of distilled water to get to 40%. It would leave you with 67.6 total oz.

This is a simple excel spreadsheet that took me about three minutes to create. If you have Excel you can do it yourself or if you like, or I can email it to you.

Cheers

Elricko,
Thank you very much.
I have alot to learn.
The simple algebra has been eluding me.
I would love the excel spreadsheet.
My email is ,removed for privacy,
I will use it as a model for all other necessary equations.
Again thanks for your help.

John,
Thank you also, you were very helpful.

The e-mail addresses are kept 'unlisted' for the privacy. For something = such as this, we would be happy to be a 'go-between', and forward your = information if you wish. Just e-mail us, along with a note on who it is = to be forwarded to, and we will do so.

Elricko,
what equation did you put in the add h20 cell to lower the ethanol and raise the total volume.

Okay Guys:

I forwarded the Excel file to Rick so he can forward it on to any of you who want it. Just email him and ask for the 'Alcohol Calculator'.

By the way, you can use different ounces. For example say the first column you have a pint with 58% and the next you have a quart of 70%, just put 16 oz in the first column and 32 in the second.

James when you get the spredsheet you can look at the equations. I hope it works well for Ya'll.

Cheers
