I just finished up some freeze distillation and was wondering if anyone had a good way to estimate the finished ABV of a freeze distilled drink.
I started with a hard limeade cooler I made that was 12% and then freeze concentrated it twice and ended up with around 1/4 the original volume.
The finished drink doesn't freeze in my freezer that is set around 0F which tells me its fairly high ABV and should tell me its minimum percentage but I don't know the formula to figure that out. Another estimate I was using was if I got 80% of the alcohol out it should be around 38% ABV. So any simple tests anyone knows of to test a solutions ABV? Its supposed to get to about -25c (-13F) in the next few days so I might use those temperatures as another freeze test.
EDIT: some basic google research is telling me that it's approximately 35% to not freeze at 0F.
