it would go. I think my reading of 0.990 is still in error still
because I measured it before I let the solids drop. Last night I put
200 ml in the fridge and only a few minutes ago I remembered why I
did it, to test it with out sediment. It did'nt change much, 0.991 @
20 C, so I got about 12.314%. I'm happy with that. I have found
using a heated bath setup is bring some consistency to my fermenting,
keeping consistent temps have got to better.
- I'm coming in late on the discussion. Missed two whole
days... That like a life time in this group. Ther
aree a heap of replies but here's a short cut for
calculation alcohol %
Take out decimals.
Start 1085 - 900 = 185 / 7.36 = 25.1% alcohol
Divide the difference of start & Final by 7.36! Voila!
