Another way to work out the potential alcohol of a wash is to subtract the

final gravity from the original gravity, and then divide the result by 7.36.

ie 1090-985=105 divide by 7.36=14.266%

Procule,

You may find that you need two hydrometers ...

One hydrometer for the wash - to cover the range say from 0.985 up to 1.20+

This will let you work out the amount of sugars present before & after

fermentation, so that you can work out the amount of alcohol you've made.

To do this, muliply the difference between the starting gravity (SG) and

finishing gravity (FG) by 129, eg: if your sugar/water mix of SG=1.120

drops to 0.980, then you have a wash with (1.120-0.980)x129=18.1%.

Another hydrometer for the spirit - say from 0.78 up to 1.00, so that you

can then work out how much ethanol is in the spirit (as per the table or

graph I posted earlier)

I doubt that you'd find one hydrometer that would accurately do both ends

of that scale for you.
