Nucleus Paragon Espresso Chilling Rock (Pack of 6)

Aroma volatile compounds play a key role in our perception of flavour. Typically, they evaporate, filling the air with the scent of coffee we know and love. To keep more flavor in the cup, weve partnered with Zurich University to create the Paragon, a tool which dramatically increases retention rates and maximises the potential of the brewing process. 

Design backed by science The Paragons patented design utilizes innovative extract chilling technology to elevate your brewing experience. Resulting from years of extensive research, the tool has been scientifically proven to capture and express up to 40% more key aroma volatile molecules than an identical brew without chilling – flavor that would otherwise be lost to the environment. 

Layers of innovation 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 center maintains colder temperatures for longer, and freezes faster than hollow or water-filled alternatives. 

Adjustable height Height-adjustable to accommodate different cups and coffee machines and is designed with anti-slip grips. 

Chilling for espresso The 30mm diameter chilling rock size is smaller than our Paragon Filter rocks and has been designed to suit espresso coffee with extra rocks available to order too.
