Calculating potential alcohol percentage from Fermentation
based on amount of sugar used

Calculate potential alcohol based on amount of sugar and total mash volume
(note: use total volume being fermented, not volume of water used)
This will tell you the alcohol percentage after fermentation based on sugar usage

Dilution Ratio

Calculate how much base alcohol and distilled water to mix in order to dilute high-proof
alcohol to a given final percentage

%abv alcohol of base %abv desired

parts base to  parts distilled water

Calculating required amount of alcohol needed to obtain a specific
proof in a finished liquor or 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)

Converting sugar weight to volume

Calculate the volume of sugar needed in place of weight

General Conversions

Many of our items, because of being imported from a European country, have pertinent information listed only in Metric.  Unfortunately, this information is often not helpful in the US where measurements are in the Imperial system. In addition, sugar addition for essences are listed in grams.  This is of no help for those without extremely accurate kitchen scales. We have therefore created the tables below to help in making your liqueurs.
