Is there a way to determine the percentage of alcohol in a mixture????? A way that can be done in the home shop???
I'll get to the point. I have a batch of wine that has completed fermentation and would like to determine the alcohol percentage.

The current method used is to use a wine hydrometer and measure the specific gravity of the slurry just minutes or a few hours after slurry is mixed and created (i.e. BEFORE fermnetation starts).

I've already done all of the googling and asked the wine store experts. I just don't believe that the alcohol content can be determined before the alcohol is produced by fermentation. Or can it??? I've wondered about this for decades.
