After digestion, samples were distilled using a steam distillation unit (Büchi Analytical Inc., New Castle, DE, USA) with 30% (w/v) NaOH.
The material from SSF was distilled in a small distillation unit before anaerobic digestion (AD).
When fermentation was complete, all ethanol was distilled from worts using a laboratory distillation unit consisting of a distillation flask, a Liebig cooler, a flask for collecting ethanol, and a thermometer.
The results can be also seen as rules-of-thumb for designing and evaluating the performances of a multiple-effect distillation unit, based only on the properties of the solution to be distilled, in particular, the boiling point elevation.

Like distilling a perfume.
But distilling remains illegal.
It's almost distilling itself.
An apt metaphor would be whiskey distilling.
Distilling the ingredients is not easy.
