Quintessence · Bench No. 3 · The Old Customs House, Fremantle

The heart is a decision.

One glass still. 120 ml of charge. Somewhere in the run — after the solvent flash of the heads, before the tails drag everything into wax — the heart comes over, a few degrees wide. Run the flame. Watch the head. Cut when you believe it.

Flame heats · head tells the truth · rail catches the cut

Your browser could not light the still — the canvas failed to start. The bench needs a 2D canvas to run; the method below still reads true.

Cut — route the drops

Three moves, one of them irreversible.

i.

Charge

Choose what goes in the flask. Iris root under fir resin. Bitter orange bough, blossom still on it. Smoked cedar laid against dark rose. Each charge carries its own heads, its own heart, its own tails — and its own temperatures.

ii.

Flame

Heat is the only argument you have with the still. Too little and nothing moves. Too much and the pot scorches, the still surges, raw charge spits into your receiver. The head thermometer tells the truth: when it plateaus, a single fraction is coming over clean.

iii.

Cut

Three receivers on the rail. Heads are solvent-bright and expendable. Hearts are why you are here. Tails are wax and drag. Route the drops, then seal the hearts — the essence you bottle is exactly, only, what you caught.

Reading the head

The flask thermometer tells you how hard you are pushing. The head thermometer tells you what is actually crossing the swan neck. While a single fraction boils over, the head holds a plateau — the mixture spends your heat as vapour instead of temperature. When the plateau breaks upward, the fraction is spent and the next, heavier one is walking up the neck.

So the craft is patience with a knife in it. Bring the charge up slowly. Let the heads flash over into the first vial — they smell like nail polish and regret. When the head settles into the low eighties, cut to hearts and hold your nerve. When it starts to climb again, cut away — one minute of greed drags a week of wax into the bottle.

And mind the pot. Past 112° the sugars burn onto the glass and every drop after tastes of smoke. A starving flask on a tall flame will scorch in seconds. Distillers say the still forgives everything except impatience — that is a lie. It forgives nothing.

“Everyone asks how long a run takes. The honest answer is: the heads take an hour, the hearts take your whole attention, and the tails take advantage.”
