Assume
1. I have moments of coordination issues and stepped on my hydrometers with a big fat stupid boot.
2. The wash has been in for 17 days and looks ok
3. heading out for a few days at the end of the week and don't want the wash to go to long.
4. Off grid with zero nearby shops to buy new 'is it done yet' devices
So, the question is, how do I know if it's done yet, and if not can I go early (distillation event) and just get a smaller output if I'm early. While I'm ou, I'll go near the big smoke and buy new glass things.
