Know before you buy
By instantly cooling the espresso as it extracts, these rocks help capture volatile aroma compounds that are typically lost to heat. This process results in a more complex flavor profile and a more aromatic cup.
The Nucleus Paragon rocks are specifically designed to be used with the Paragon Espresso system. They are sized to fit securely under the group head to ensure efficient cooling during the extraction process.
No, these rocks do not dilute your coffee. Unlike ice cubes, they are sealed, food-grade stainless steel spheres that provide cooling without adding any water to your drink.
The rocks are dishwasher safe, making them easy to clean. Because they are made of durable, titanium-coated stainless steel, they are designed for repeated, long-term use.
For optimal performance, store the rocks in your freezer until they are thoroughly chilled. Because of their high-density liquid core, they are designed to hold that cold temperature effectively during the extraction.
While they are engineered specifically for the espresso extraction process, they can technically be used to chill any beverage. However, their size and design are optimized for the flow and temperature requirements of espresso.
