Is my calculation correct !

Post by trickybrew » Sun Jun 07, 2015 1:43 pm

Hi I just done my 1sr reading on the 9th day so far, and was wondering if my calculation for alc is correct!

1st day reading 1044

Day 9 reading for 1st ach reading

That looks like 1012 to me
And if I've worked this out correct its 4.3% alc
Is this correct to you guys please
Thanks

Tricky don't worry you got it right, different website calculators will give slightly different answers - some 4.2 others 4.3.

I learned to work it out as follows:

OG minus FG divided by 7.46

So.....

44 minus 12 = 32

32 divided by 7.46 = 4.289544235924933

4.3% ABV to 1dp

Don't sweat the 0.1%. Your hydrometer is not that accurate...
