double boiler is constructed with the kettle in there. Double boil is to prevent any nasties from happening. It keeps your distillery at a nice even temp not to hardcore. You see I don’t have it on an element directly… ever wonder how to not get fusel oils into your alcohol? grrr fucking spellcheck says fusel isn’t a word lol. I have drilled a hole in the top of the kettle to put the pipe in.
