LINK Sample Coffee Roaster by Nucleus × Kaffelogic

LINK Sample Coffee Roaster — Origin Roasting, Anywhere

The LINK is a collaboration between Nucleus Coffee Tools and Kaffelogic, bringing together two of the specialty coffee industry's most respected small-batch roasting minds. The result is a portable sample roaster loaded with over 1,000 preloaded roast curves developed by Sam Corra of ONA Coffee — one of Australia's leading specialty coffee professionals.

The companion app selects roast profiles based on bean density, matching the roast curve to the physical characteristics of the green coffee rather than requiring the user to develop profiles from scratch. This makes the LINK immediately useful even for roasters who are new to sample roasting at origin.

A shock-absorbent waterproof travel case protects the roaster during transit to origin farms, cupping labs, and competitions. Accessories include a dosing cup and coffee tray. The LINK is the essential tool for green coffee buyers, quality control teams, and roasters who need to evaluate coffees in the field.
