The Nucleus Link isn’t just a sample roaster, it’s a powerful tool for coffee professionals who demand control, consistency, and community, wherever they go. Whether you’re sourcing at origin, cupping with your team, or refining your roast profiles back at the lab, the Link delivers world class results in a compact, travel ready format.

With real-time data feedback, altitude calibration, and an innovative heating system that roasts from the inside out, the Nucleus Link ensures your samples are expressive, clean, and repeatable without the “gassy” taste often associated with fresh roasts.

At the heart of the Link is a roast engine backed by 205 expertly developed profiles created by Sam Corra over three years of testing. These profiles are designed to cup globally and allow green buyers, roasters, and coffee pros to achieve accurate results without guesswork. The LINK app unlocks advanced tools like Density Roast Prediction, DTR override, and custom profile creation to help dial in with surgical precision.

Nucleus Link Key Features:

• Altitude Calibration
  Mimic sea-level roasting at any elevation. Adjust fan speed to suit air pressure, ensuring consistent movement and heat transfer across all sample sizes.

• Complete Profile System
  Access 205 core roast profiles for filter and cupping, grouped into inboxes based on roast development and curve style. Plus, design and store your own with the 6th inbox for custom profiles.

• Density Roast Prediction
  Input your green coffee's density, and the app recommends the most suitable profile for optimal development and flavour clarity.

• Advanced Dial-In Tools
  Refine post-roast with precise control over DTR (Development Percentage, Time, Roast Degree) and temperature increase range.

• Variable Batch Size
  Roast from 50g to 100g in 1g increments, perfect for sample testing or mini-experiments. Fan calibration adjusts automatically for accurate results.

• Inside-Out Heating Technology
  The Link’s new thermal system applies heat from the inside out, generating faster momentum in your roast curve with less CO₂ build up. Taste your samples at peak freshness.

• Ready to Travel
  Includes a shockproof and waterproof travel case, dosing cup, density tube, and coffee tray, everything you need to roast on the road.
