From wort to wash
After mashing, sugar-rich wort is cooled and fermented with yeast. Yeast converts sugars into alcohol and carbon dioxide while also creating esters and other aroma compounds that may remain recognisable later.
Yeast strain, temperature, fermentation time and microflora can influence fruity, floral, cereal and acidic notes. Longer is not automatically better: the distiller wants a suitable, repeatable foundation.
- Yeast creates alcohol and aroma compounds
- Still shape controls reflux and copper contact
- Only the selected middle cut goes to cask
What distillation selects
As the wash is heated, alcohol, water and aroma compounds vaporise and condense at different stages. Still shape, heating rate, reflux, condenser and copper contact together influence what passes through.
At the spirit safe, the distiller separates foreshots, heart and feints. Only the selected heart is collected as new make for maturation; other fractions may be distilled again.
Taste the process
Compare a light, fruity style with a heavier, oilier one. Alongside apple, pear, banana and flowers, look for cereal, mineral, meaty or sulphury notes: none is a quality score by itself.
An active cask can cover the spirit style. Younger bottlings or whisky from refill casks sometimes show that foundation more clearly. Then use the aroma and cask guides to separate process from maturation.
