Alcohol Content?

[jonereb]

I'm making one gallon of blackberry wine and one gallon of cherry wine. Here are my hydrometer readings for each.

CHERRY:
1.070 (raw fruit sugar)
1.100 (12 hours after adding sugar)

BLACKBERRY
1.030 (raw fruit sugar)
1.100 (12 hours after adding sugar)

I'll add Cotes des Blanc yeast in 12 more hours. Cotes leaves a little residual sugar. How do I measure the alcohol content? Do I wait for fermentation to finish, and then take another hydrometer reading? Probably about 1.010 or 1.000???

ABV = (OG-FG) * 133

You're right, FG will probably be around 1.005 plus or minus.
