Kaffelogic Nano 7 Profiles: Complete Library & Download Guide

A Kaffelogic Nano 7 is only as good as the profile running on it. The machine's whole promise — repeatability — depends on picking the right profile for the bean, running it at the right level, and learning from the result. This guide covers the complete profile landscape: what the families mean, which community profiles people actually use, and how to choose one for your next roast.

First: What a Kaffelogic Profile Actually Is

A profile is a temperature curve the roaster follows, plus a level — the point on that curve where the roast ends. The level is your roast-degree dial: higher number, darker roast. Two consequences matter:

• Levels are profile-relative. A 2.5 on one profile is not the same roast as a 2.5 on another.
• Track metrics, not color. Roast loss, total time, first-crack time, and DTR (development time ratio) tell you more than bean surface color — and they're what make a roast repeatable.

The Three Profile Families

F-Series (Kaffelogic standard, altitude-matched). Named by process and altitude band — F-WSH 1500-2200 is washed, 1,500–2,200 m. Reference batch 120 g, gentle preheat (~790–870 W), first crack ~203–213 °C, balanced 16–22% DTR. Forgiving and consistent — the right starting point for most beans.

NCT (Nucleus Link competition packs). Built for the roaster that won two World Brewers Cups. Organized by goal: Filter A (sweetness/body), B (brightness/acidity), C (all-rounder), D (medium-dark complexity), E (light/gentle), plus Espresso, Omni, and Cupping packs. Reference batch 100 g, high preheat (~970–1040 W), short decisive roasts (~6–7 min). Full NCT guide →

Forum / community profiles. User-designed and battle-tested — NordicLight (fast, Scandinavian-style), Raost variants (Scott Rao-style curves for bright Ethiopians), 9minFilter, and hundreds of bean-specific profiles shared by other Nano owners.

For the measured differences between the first two families — preheat, first-crack marker, timing and results on the same beans — see NCT vs F-Series compared by the numbers.

The Community's Most-Downloaded Profiles

From the kl-profiles.com community library — what Nano owners actually roast with:

Downloads are a popularity signal, not a quality guarantee — a profile with 50 downloads that matches your bean beats a famous one that doesn't.

Choosing a Profile for Your Bean

Step 1 — Family by process and goal:

Step 2 — Level: start at the profile's designed level, then adjust in 0.1–0.2 steps. For F-Series light filter roasts, levels 1.8–2.5 are typical; medium-light, 2.3–3.0. How many degrees a step is worth depends on the profile: see Kaffelogic roast levels in degrees.

Step 3 — Batch size: 120 g for F-Series, 100 g for NCT and forum profiles. Never below 80 g on a standard profile — 100–120 g is the Nano 7e's thermal sweet spot.

Step 4 — Evaluate after resting: 7–10 days for washed Ethiopians and Kenyans, 5–7 for naturals. Cupping early misdiagnoses good roasts.

See it on real beans. Each of our roast logs follows one coffee through every attempt: which profiles were tried, at which level and batch size, and how each cup tasted.

• Kenya Gatugi Peaberry roast log: washed Kenyan, settled on F-WSH 1500-2200
• Ethiopia Sidamo roast log: washed Ethiopian, settled on NCT Filter E
• Ethiopia Yirgacheffe roast log: washed Ethiopian, settled on NCT Filter E
• Colombia ASOSPAC roast log: washed Colombian, settled on NCT Filter B
• Honduras La Flor roast log: washed Honduran, settled on NCT Filter D
• Colombia SL 28 natural roast log: a natural still being dialed in

How to Import Profiles (The Official Way)

1. Download the profile pack (Kaffelogic's downloads page or a community share) and unzip it.
2. Open Kaffelogic Studio, connect the roaster, and click View roaster.
3. Go to the Profiles tab → Add profile, select the files, done.

That workflow is also the clunky part: desktop-only, USB-tethered, and nothing tells you whether the profile actually worked for anyone. The same library is also browsable at roast profiles (including the filter hub for light and pour-over goals). BrewedLate Roasting puts it in the browser — browse by bean and goal, plan the roast as a checklist, then upload the .klog afterwards and get AI suggestions for the next adjustment. Free, demo mode without signup. Already roasting? Open your roastery to see your logged batches, cellar, and roast history, or drop a .klog into the Kaffelogic log viewer to see its curve without an account.

What Worked for Other Users

Community signals from logged roasts: the F-WSH 1500-2200 profile has the deepest track record for high-altitude washed beans (and fails mainly when run below level ~2.3 — too light). Adaptive_Raost_NCC's popularity comes from forgiving, bright light roasts across origins. And across dozens of logged roasts in our own testing, the same three mistakes explain most failures: wrong pack for the goal, level outside the design window, batch too small — in that order.
