Hi, Ode, Thanks for the concise overview!
It might be added that for those who use a quart or more a day, a home distiller may pay for itself in one year or less. Furthermore, rebrewing can reduce the cost of DW usage. And pre-heating feedstock water with a separate heater using less expensive or free fuel might be worthwhile (e.g. in remote areas in an underdeveloped country.) Best regards, Matthew
