If I were to create a still (temperature control was my first concern but technology has progressed since Al Capon and prohibition and I live on the Moon where laws are different) if I where aiming for 95% alcohol I can also get methanol not just ethanol and I hear that would make you go blind. I feel I've been shunned from brewing forums for posting about genetically modified yeast to make THC so you can have a drink and get stoned. Maybe they had a purest attitude and I was too fringe. But now I could be entering danger levels. Alcohol has a lower boiling point than water and I could set the temperature, say 80, 85, 90, 95C, no explosions or fire happen. But, if I did this, are there poison hazards? I don't know how many names alcohol has.
