ALCOHOL CALCULATIONS

by Harry Lythall - SM0VPO

Here are a couple of usefull formulas for calculating alcoholic
content (by volume) when brewing or distilling. They may not be 100%
accurate due to other variables not considered, but probably within
one per-cent, or so. The boiling point of Ethyl alcohol has been
assumed as 78.8ºC at sea-level.

##
Deciding Alcoholic Content of Mash

This formula tells you the specific gravity and potential alcoholic
content when a specific amount of sugar is added to 1-liter of water,
then fermented. Note that every yeast has its own alcohol tolerance
level which also limits the maximum alcohol yeald possible.

##
Estimating Sugar Content

Enter measured specific gravity x1000 (1.090 = 1090) to show the
potential alcohol and quantity of sugar contained in one liter
of mash.

##
Measuring Alcoholic Content of Mash

Measure the temperature of the boiling mash and enter it here.
Note that the temperature is multiplied by 10 so 90 degrees
centigrade is entered as 900. This calculator only provides a rough
guide.
