The Basics of Molecular Distillation - Marijuana Venture

Jul 15, 2020 An Old Process. Distillation itself is an old process, one used in many industries, but most notably for making alcohol. Traditional short-path distillation, like that of an old moonshine still, uses a boiling flask to heat the material so it evaporates and is caught on a condenser above. The mash is heated in the flask and the alcohol boils off first.
