Every bottle of whisky begins with ingredients, fermentation and a still. But one of the most important decisions happens during distillation itself:
What does the distiller keep, and what gets left behind?
This decision is known as making the cuts.
During pot distillation, the spirit flowing from the still constantly changes. Different compounds appear at different stages of the run, bringing different aromas, flavours and textures.
A skilled distiller must decide exactly where one section ends, and another begins.
These decisions help determine the character of the spirit long before it enters an oak barrel.
As fermented liquid is heated in a still, alcohol and other volatile compounds evaporate and travel through the still as vapour.
That vapour is cooled, condensed back into liquid and collected.
But the liquid coming from the still isn't identical throughout the process. Its alcohol strength, aroma, flavour and texture evolve continuously.
Distillers therefore divide the run broadly into three sections:
Heads → Hearts → Tails
The moments when the distiller changes from collecting one section to another are known as the cut points. Blogs Spirit Cuts
The heads—or foreshots—appear early in the distillation run.
This portion contains highly volatile compounds and can display sharp, solvent-like or excessively fruity aromas and a prickly character.
For a distiller, recognising these characteristics is an important part of deciding when the desirable portion of the spirit has begun.
Then comes the part every distiller is waiting for:
the heart.
The heart contains the desirable balance of ethanol and flavour compounds that will form the foundation of the finished spirit.
This is where the character created through the raw ingredients and fermentation begins to shine through.
Clean doesn't necessarily mean flavourless.
The objective is to capture a spirit with balance, character and texture that can eventually develop further through maturation.
Later in the run come the tails, sometimes called feints.
These contain heavier compounds, including higher alcohols and oils, which can introduce richer, heavier and sometimes waxy characteristics.
Some early-tail character can potentially add richness and complexity, while excessive tails can make a spirit feel heavy or coarse. Blogs Spirit Cuts
This is why there isn't simply an automatic point at which every distiller makes the same cut.
Cut points can dramatically influence the style of the final spirit.
A narrower heart cut generally favours a cleaner, more refined spirit.
A wider heart cut can retain more flavour compounds and complexity, but can also introduce heavier or harsher characteristics if taken too far.
The source document puts the principle simply: cut points help determine the spirit's balance and character before ageing or blending even begins. Blogs Spirit Cuts
There is no single measurement that replaces experience.
Distillers use a combination of measurement, aroma, timing and sensory judgement.
Alcohol strength changes throughout a distillation run, providing useful information about how the run is progressing.
But numbers alone don't tell the whole story.
The aroma changes as well.
Early spirit can smell sharp or solvent-like. The heart becomes cleaner and more balanced, while the later stages develop heavier aromas.
After working repeatedly with the same still, wash and production process, a distiller also develops an understanding of how that particular still behaves.
That's where science and experience meet.
At Ancient Wisdom Distillery in Pakenham, Victoria, our whisky production combines fermentation, copper pot distillation and extended barrel maturation.
Our Australian single malt whisky is double-distilled before beginning its long maturation in carefully selected oak barrels. Our current French Oak Chardonnay expression, for example, is matured for eight years in French oak barrels previously used for Chardonnay. Ancient Wisdom Distillery
The decisions made during distillation create the foundation.
The barrel then takes over.
Over years of maturation, the spirit interacts with the oak and the previous character of the cask, gradually developing colour, aroma, texture and complexity.
It's why we see distillation and maturation not as separate processes, but as different chapters in the same story.
Great whisky doesn't begin after eight years in a barrel.
It begins much earlier.
The distiller's decisions about heads, hearts and tails influence what goes into that barrel in the first place.
Temperature and measurements provide information.
Aroma provides information.
Experience provides judgement.
And ultimately, knowing what to keep and what to leave behind is part of the craft of distillation.
At Ancient Wisdom, we then give that carefully selected spirit something equally important:
time.
