Precision Roasting
The Link guarantees consistent and repeatable results under any conditions. Its integrated Altitude Calibration, Density Roast Prediction, and DTR (Development Time Ratio) override systems automatically adjust airflow and heat based on altitude, bean density, and processing type. Developed in collaboration with Sam Corra, these profiles ensure an ideal balance between sweetness, body, and clarity.
Innovative Heating
The Link’s advanced convection system heats beans from the inside out, maintaining stable momentum and optimal heat transfer throughout the roast. Starting from ambient temperature enhances flavour clarity and freshness — an essential feature for accurate sample evaluation.
Portable Design
Built for professionals on the move, the Link combines robust engineering with full portability. It comes in a shock-proof and waterproof case, keeping your equipment protected during transport.
The kit includes:
- Dosing cup
- Density tube
- Coffee tray
Ready to roast immediately upon arrival — no tools or setup required.
Nucleus Studio and Link App
The Link works seamlessly with or without software. Using the Link App and Link Studio, you can:
- Calibrate according to altitude
