Developed in collaboration with Zurich University of Applied Science (ZHAW), this revolutionary coffee brewing system has redefined the boundaries of flavor preservation and extraction. In this article, we will explore the science behind the Paragon Nucleus and delve into its remarkable features that contribute to an unparalleled coffee brewing experience.

What is the Paragon Nucleus?

The Paragon Nucleus is a groundbreaking coffee brewing system that harnesses the power of extract chilling technology and precise temperature control to capture and express the full spectrum of aromatic volatile compounds in coffee. With its remarkable features and benefits, it has the potential to revolutionize the coffee brewing industry and redefine the way we experience the flavors of coffee.

At its core, the Paragon Nucleus incorporates extract chilling technology, which allows for precise temperature control throughout the brewing process. By maintaining optimal temperatures, this innovative system captures and expresses a higher percentage of key aroma volatile compounds, resulting in a more flavorful and aromatic cup of coffee.

One of the key components of the Paragon Nucleus is the Paragon Chilling Rocks. These chilling rocks are specifically designed to optimize the extract chilling process. With a high-density liquid-filled core, a unique sphere shape, and a large diameter, the Paragon Chilling Rocks facilitate efficient flavor preservation by rapidly chilling the coffee extract over a large surface area. These rocks are titanium-coated for increased durability and are made from food-grade stainless steel, ensuring safety and quality in every brew.

The Paragon Nucleus offers several advantages and benefits to coffee enthusiasts. By capturing and expressing up to 40% more volatile aroma compounds compared to traditional brewing methods, it enhances the flavor profile of the coffee, resulting in a richer and more complex taste experience. The Paragon Nucleus is designed to be compatible with various vessels and pour-over brewers, allowing users to integrate it seamlessly into their preferred brewing setup.

The Paragon Nucleus is not just a brewing system; it represents a paradigm shift in coffee extraction. Founded by Sasa Sestic, a World Barista Champion and coffee professional, the Paragon Nucleus is the culmination of his relentless pursuit to extract every drop of flavor from each coffee bean. Backed by scientific institutions and a team of product testers, the Paragon Nucleus pushes the boundaries of what was once thought to be impossible in coffee brewing, delivering the best that coffee has to offer.
