Know before you buy
The Paragon uses a titanium-coated chilling rock to rapidly cool the espresso as it extracts. This process preserves over 40% more volatile aroma compounds that are typically lost to heat, resulting in a more nuanced and aromatic cup.
The mounts are height-adjustable to accommodate a variety of cup sizes. The mount dimensions are 34mm in width and 120mm in depth, so ensure you have enough clearance between your group head and the drip tray.
No, the chilling rocks are not dishwasher safe. We recommend hand washing them with mild soap and water to maintain the integrity of the titanium coating and the internal liquid gel core.
Each set includes two height-adjustable mounts and four chilling rocks. This allows you to keep a rotation of rocks in the freezer so you are always ready for your next shot.
Yes, all materials used in the Paragon Espresso are FDA-approved and food-safe. The chilling rocks are constructed from SUS304 stainless steel with a durable titanium coating.
