Paragon Filter – Chilling Rocks (5-Pack)
SKU: PG-ROCK5
Material: Food-Grade Stainless Steel + Phase Change Core
Designed For: Nucleus Paragon Extraction System
The Paragon Chilling Rocks are a key component of the Nucleus Paragon, a groundbreaking extraction system that improves brew quality through post-brew chilling. These reusable rocks are engineered to cool brewed coffee instantly and precisely, preserving delicate aroma compounds and volatile flavors otherwise lost in hot extraction.
Each rock features a food-safe stainless steel outer shell and a phase-change cooling core—ensuring fast, efficient heat transfer without diluting or contaminating your brew.
Designed for the Nucleus Paragon
Specifically engineered to integrate into the Paragon’s chilling module, maximizing surface contact and flavor capture.
Phase Change Cooling Core
Each rock contains an internal phase change material (PCM) that rapidly absorbs heat at a consistent rate—cooling the coffee immediately after it leaves the filter.
Reusable & Hygienic
The stainless steel construction is non-porous and easy to clean, ensuring long-term use with no flavor retention or contamination.
Consistent Results
Stabilizes extraction by halting post-brew chemical changes. Ideal for high-acidity or aromatic coffees.
Comes in a Pack of 5
Ideal for back-to-back brews, flight cuppings, or multi-station setups in cafés and competition stages.
