The Ziegler distillery operates the double-distillation process: raw distillation, then fine distillation.
The mash is gently heated by steam in vats with mixers and the raw distillate is produced. The second distillation processes yields the refined distillate, of which we retain only the heart, the Ziegler fine eau de vie.
The separation of the heart of the distillation run is performed, as it has been for centuries, by human senses. The master distiller´s nose decides.
