* All boiling temperatures at altitude of 0m (i.e. at standard atmospheric pressure 101.25kPa). If distilling at other altitudes/pressures, adjust the temperature in "Unit conversion" Tab.
* All %abv readings measured at hydrometer calibrated temperature of 20°C. If measuring %abv at other temperatures, adjust the %abv reading in the "unit conversion" tab.

* The minimum amount of water is used when vapour is just condensed and the distillate still hot. Increasing the waterflow through spirit condensor will further reduce the temperature of distillate.
