8 Ways Distillation Affects The Whisky

1. Alcohol Strength & Purity

Distillation determines the alcohol percentage in the whisky. Higher distillation leads to a lighter, cleaner spirit, while lower distillation contributes to a richer character.

2. Flavour Profile Development

The shape and size of the still impact which flavour compounds are retained or removed. Tall, slender stills encourage lighter, fruitier notes, while shorter, wider stills allow for heavier, smokier flavours.

3. Retention Of Congeners

Congeners are compounds that influence aroma and taste. A slower distillation process allows more of these to be carried into the final spirit.

4. Impact Of Copper Contact

Copper in the stills helps remove sulphur compounds, preventing off-flavours like rotten eggs or rubber. More copper contact results in a smoother, refined whisky.

5. Reflux & Whisky Texture

Reflux refers to the process where the vapour condenses and re-evaporates within the still. More reflux produces a lighter, silkier whisky.

6. Foreshots, Hearts & Feints Selection

The cut points, where distillers decide to keep or discard spirit fractions, affect whisky quality. The ‘hearts’ contain the purest flavours, while ‘foreshots’ are harsh, and ‘feints’ contain heavier, often undesirable compounds.

7. Single, Double Or Triple Distillation

Single distillation retains more raw flavours. Double distillation strikes a balance between richness and refinement. Triple distillation creates an ultra-smooth, delicate spirit.

8. Influence On Maturation

The final distillate affects how whisky interacts with the barrel. Lighter spirits extract delicate vanilla and floral notes, while heavier spirits draw deeper caramel, spice, and smoky elements.
