Extract-Chilling: Stop Losing the Best 40% of Your Coffee Before You Even Taste It

You brew that intense anaerobic Gesha.
Or a natural Sidra packed with tropical aromatics.
The fragrance is unbelievable.

And then — halfway through the brewing process - you already lost most of those volatile aromatic compounds. They're long gone before you even take the first sip.

That’s the reality: up to 40% of coffee’s most expressive aromatics evaporate the moment hot liquid hits air.
All the fruit, florals, and fermentation nuance that make these coffees special… simply drift off.

The Origin of Extract-Chilling

The principle has existed for years, but it was Hugh Kelly — three-time Australian Barista Champion and WBC competitor — who formalised and demonstrated it on the world stage.

In 2021, he used frozen stainless-steel spheres to instantly chill espresso mid-extraction during his World Barista Championship routine.
The result was groundbreaking: a measurable increase in retained aromatics and a noticeably more layered, expressive cup.

His work sparked the foundation for the extract-chilling methods we use today — and directly influenced the creation of the Paragon system.

Extract-chilling solves that problem.
Lower the temperature of the brew path below ~35°C immediately after extraction, and those aromatics stay in the liquid — where they belong.

Where the difference becomes obvious

Natural, anaerobic & heavily processed coffees

These coffees respond the most dramatically:

• Normal cooling → expressive in the aroma, flatter in the cup

• Extract-chilled → structure tightens, clarity improves, fruit becomes more defined, texture becomes smoother and silkier.

Side-by-side, the difference is hard to ignore.

Washed coffees

• Cleaner and silkier

• Slightly sweeter

• A refinement rather than a transformation

Worth using, but the biggest impact is on aromatic, fruit-forward lots.

Why traditional extract-chilling doesn’t work at home

• Ice in the brew path → dilution destroys structure

• Frozen cups or portafilters → inconsistent and unpleasant drinking-experience.

That’s why the Paragon exists:
to make extract-chilling repeatable, efficient, and clean — every single time.

The Paragon: Extract-Chilling Designed for Real Brewing

• Brew directly over the pre-frozen chamber

• Gentle swirl for 15–20 seconds

• Temperature drops rapidly from 80°C+ to ~30°C

• Absolutely no dilution.

• Aromatics stay intact.

It takes less time than adjusting your grinder.

Bonus: The best ''ice-cubes'' you'll ever own.

The chamber is solid stainless steel, it also doubles as the best “ice cube” you’ll ever own:
perfect for iced lattes, espresso tonics, and cold coffee cocktails — without watering anything down.
