Makes sense. I froze a batch of fresh squeezed cherry juice. Months down the road, I pulled the jug from the freezer and it was all frozen, except for a little over an inch cylinder down the center. That would be the high concentrate, which had an out of this world, wonderful taste. High sugar.

You need a cheaper source for alcohol. I just picked up another 5 gallon jug while using a 25% off coupon. $42.20 shipped to my door.

The advantage of alcohol is there is almost zero labor. So instead of adding labor to recover alcohol why not just use a slightly more labor intensive method instead, like boiling or a kiln.

Distillation is not feasible for most individuals. I do my fair share at work but don’t see it as feasible for most guys to do at their house. You also get into another fun area frowned upon by law enforcement.

Freezing… You will need to get water content up over 70% by weight to get freezing. I routinely use ethanol/water mixtures at temperatures below zero with no issues at work for crystallization work. Most guys experiences freezing alcohol products is with beer and wine products and in both cases we are talking about a lot of water. I know we kept a freezer full of MD 20/20 g at the house in college and you could “freeze concentrate” that crap and pour that horrible junk out for consumption on occasions as usually the freezer never stayed closed long enough to get that cold.

Molecular sieves and various desiccants are frequently used to dry organic solvents but once again not really feasible for most.

I think the effort and materials needed plus ones times are more costly and just would buy the denatured alcohol.

I just bought a 5 gallon bucket for $33 at Menards. Special order; took about 2 weeks to get. I soaked 8 bowls, roughly 20” apiece. https://www.menards.com/main/paint/cleaners-thinners-removers/paint-stain-cleaners/thinners-solvents/sunnyside-reg-denatured-alcohol-thinner-5-gal/p-1444444210602.htm

Thanks everybody! TravisH’s comment about needing a high % water to freeze ethanol/water blends was something I didn’t know (I will blame my Chem 101 level knowledge). AlaskaGuy’s link to wikihow was bang on. “Start with a liquid that is 5%-15% alcohol” (freezing method is also called “Mongolian Still). Thinking about it, of course it won’t work for low water contents. It if it did the vodka …~80 proof = 40% alcohol… that lives in my freezer (best martini ever…no ice needed) would have separated long ago.

All demonstrating once again …you can get darn near ANYTHING answered at LumberJocks :)
