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 flavour in the cup, we’ve 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 Paragon’s patented design utilises innovative extract chilling technology to elevate your brewing experience.

Resulting from years of extensive research, the tool has been scientfically proven to capture and express up to 40% more key aroma volatile molecules than an identical brew without chilling – flavour that would otherwise be lost to the environment.

Layers of

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.


Paragon is designed to fit your favourite vessel and preferred pour-over brewer.


Paragon is an Australian Good Design Award winner.
