Kaffelogic Studio
Free roasting software available for Mac, Windows, and Linux. Provides:
- Live roast view: real-time display of the roasting process during a batch
- Bean and fan curve control: adjust both temperature and airspeed profiles
- Levels system: +/− buttons on the machine adjust end temperature in pre-defined increments, either before or during a roast — for quick dark/light adjustments without modifying the profile
- Profile management: create, edit, save, and share profiles; works offline without a connected roaster
- Community profiles: shareable via the Kaffelogic community forum and Facebook group
Pre-loaded profiles cover the main use cases:

Competition credentials
The Nano 7 has been used in multiple World Brewers Cup (WBrC) competitions. Kaffelogic claims 2 world championship wins using the machine; Carlos Medina was the most recent WBrC champion to use the Kaffelogic. Baristas also use it in Barista Championship competition prep for sample roasting of competition lots. (source: Kaffelogic (website))
Professional use case
Beyond home roasting, the Nano 7 is positioned as a sample roaster for professional environments:
- Pre-loaded cupping and QA profiles for consistent lot evaluation
- Compact (3.6 kg, 125mm footprint) — fits on a lab bench or café counter
- Back-to-back roasting with no inter-batch wait time
- Used by specialty roasters for sample evaluation before scaling to production
- Compatible with Cropster roast logging as an alternative to Studio
See Sample Roasters for comparison with ROEST, IKAWA, and Aillio.

Relevance to Kaiserblick
The Kaffelogic Nano 7 is relevant to Kaiserblick in two ways:
- Sample roasting at origin: its compact footprint and quick cycle time make it practical for cupping green lots at the processing facility before export — strengthening the quality narrative for European buyers.
- Roast profile development: Roxanne Fredericksen leads Kaiserblick’s roast profile development; the Nano 7’s Kaffelogic Studio and pre-loaded cupping profiles provide a low-cost, low-space complement to production-scale roasting.
The lack of a Latin America distributor means direct purchase from New Zealand. No significant duty-avoidance opportunity without a regional re-seller.
Nucleus Coffee Tools Partnership
Kaffelogic maintains a significant technical and commercial partnership with Australian manufacturer Nucleus Coffee Tools:
- LINK Studio software (the desktop roasting software for the Nucleus LINK sample roaster) is hosted on Kaffelogic’s web infrastructure at
webservices.kaffelogic.com - The two companies jointly sponsor the WCRC (World Coffee Roasting Championship) as co-official sample roasters from 2024 to 2027
- The LINK and the Nano 7 represent complementary products from the same Oceanian specialty ecosystem: the LINK maximizes portability and competition branding; the Nano 7 offers broader batch-size flexibility and deep open software control
