The chilling rock is a core component of the Paragon. Constructed from food-grade stainless steel and coated with a layer of highly durable titanium, its spherical shape and large surface area allow for even and rapid chilling. Offering greater thermal capacity, the high-density liquid gel centre maintains colder temperatures for longer, and freezes faster than hollow or water-filled alternatives.

FAQs
Will the Nucleus Paragon Espresso fit my machine and cup/scale setup?
Yes. The Paragon Espresso mounts are designed to fit most commercial and home espresso machines, accommodating standard cups and scales beneath the portafilter. The adjustable height allows for seamless integration into your existing coffee extraction espresso workflow.
How do I use the Paragon espresso chilling rock during extraction?
Place a pre-frozen Paragon espresso chilling rock into the mount above your cup before you extract espresso. As the shot flows, it passes over the chilled ball, cooling rapidly to preserve aromatics and reduce bitterness — a process known as extract chilling.
What ball temperature and chill time give the best espresso extraction?
For optimal results, freeze the Paragon espresso chilling rock for at least four hours before use. The ideal temperature range is between -20°C and -30°C. This ensures maximum heat transfer, enhancing flavour balance and creating the best espresso extraction possible.
Does chilling extracted espresso change flavour, crema or yield?
Yes — chilling stabilises volatile aromatic compounds that are often lost in hot extractions. This process enhances sweetness and texture while maintaining crema integrity and overall yield. The result is a more balanced, flavourful extracted espresso with greater clarity.
How do I clean and store the Paragon espresso chilling rocks and parts?
After use, rinse each extract chilling espresso tool with warm water. Dry thoroughly before placing the chilling balls back into the freezer.
