95%+ is totally possible with a column still. I can easily pull 92% on mine, and it’s not set up to do ultra high proof. Distillit percentage can easily be measured with a hydrometer, they’re less than €10, and fairly accurate. This process might be really useful to pull the last 20% of water out after distilling.
I’d love to see this experiment done on something like everclear. That’s around 95% abv. It’d be interesting to see if you could get the last 5% of water out of it. It’d also be interesting to see it done on something like an 8% abv wine or beer.
Pic related, it’s my 250 liter column still. I usually get heads that are 92% abv, and an average abv of 80% across a run.
Only if you’re a good girl.
