You have such a way with words Brian ;-).

P.s. the beautiful thing about vacuum distillation is that by using as a source of energy 60-70°C hot water flowing in a copper tube spiral inside the boiler the boiler itself can be made of plastic, e.g. the boatbuilders favorite .......GRP. By applying sufficient vacuum the boiling point could be kept around 30-40°C thus facilitating the transfer of heat/energy from the hot water to the fermented/boiling liquors.


......and Happy New Year!!!!
