Nucleus Link (NCT) Profiles: Packs & Levels Guide

The Nucleus Link is a compact sample roaster built by Kaffelogic in New Zealand, used in competition by World Brewers Cup champions Martin Wölfl (2024) and Matt Winton (2021). It shares the same fluid-bed roasting core as the Kaffelogic Nano 7e, which is why its NCT profiles can be imported and run on a Nano.

Yes. The Nucleus Link and the Nano 7e share the same roasting core, so NCT profiles import and run on the Nano 7e. Use the reference batch size of 100 g and start at the pack's recommended level — NCT levels do not map 1:1 onto F-Series levels.

Start with Filter B (brightness, acidity, fruity/floral cups) or Filter E (light-to-medium, gentle, preserves delicate flavors). Filter A and D are common mistakes for bright, origin-clarity goals — they develop too much body and mute the florals.

NCT profiles are built for short, decisive roasts: 100 g batches, higher preheat (~970–1040 W), higher first-crack targets (~215–219 °C), and typical total times around 6–7 minutes with 10–14% DTR. F-Series altitude profiles are gentler: 120 g batches, ~790–870 W preheat, first crack around 203–213 °C, and 16–22% DTR for balanced medium-light cups.

100 g is the NCT reference batch. Forum-style fast profiles (NordicLight, Raost) run best at 80–100 g. Never run a standard profile below 80 g — use a dedicated 60 g profile instead — and treat 100–120 g as the thermal sweet spot on the Nano 7e.
