There are 3 fractions in distillation:
- The so-called "head", which includes substances with a lower boiling point.
- The "heart" (the actual distillate or spirit) is the portion that contains all the precious aromas and full flavours
- The "tail" section contains substances with a higher boiling point; they are separated again.
We differentiate between two types of distillation: batch and continuous distillation.
In batch distillation, the still is filled with mash or pomace, distilled and then emptied. The boiled remains, the so-called slurry, is completely removed from the cycle.
Continuous distillation is an ongoing process in which the apparatus is continuously filled with mash or pomace and distillate is continuously extracted.
