Effortless extract chilling for espressos. Say goodbye to makeshift setups, Nucleus brings the Paragon Chilling Rock to your espresso routine with this clever, lightweight design. Just place the Paragon Espresso on top of your cup and pull your shot as your normally would. Easy! This set includes 4 Paragon Chilling Rocks and 2 Paragon Espresso Mounts.

Enhanced flavours

Developed in collaboration with Zurich University of Applied Science (ZHAW), the Paragon Chilling Rock quickly cools down the extracted coffee as it touches the rock, locking in more flavours that would otherwise have been lost without the chilling technique.

In ZHAW’s research on volatile aroma compounds, they discovered that instantaneous cooling of the extraction would trap these compounds and result in more aromatic and flavour-rich coffees.

Optimal cooling

Unlike ordinary whiskey rocks, the Paragon Chilling Rock is specifically designed for use with coffee. They are made with titanium-coated stainless steel making them incredibly durable. Inside, these rocks are filled with a high-density liquid to keep them at the optimal temperature needed for effective extract chilling. They’re also designed to rapidly and evenly cool the coffee extraction that touches them.

Paragon Espresso Mount

No more balancing acts and makeshift stands! The Paragon Espresso Mount serves as a stable platform for the Paragon Chilling Rock and can be easily set on top of any cup. This custom mount is height-adjustable to accommodate different cups and coffee machines and is designed with anti-slip grips.
