Calculate Required Amount of Alcohol Needed to Obtain a Specific Proof in a Finished Liquor/Liqueur
Calculate how much base alcohol at a given percentage is required to make a finished
product with a specific alcohol content for any volume (eg. 316ml of 95% alcohol is needed
to make a 750ml bottle of 40% vodka- the rest of the bottle can be filled with water,
sugar, essence, etc., without altering the proof of the finished liquor).
