Roast profiles

The Nano 7 comes pre-loaded with a default profile called "K-logic classic." This profile makes a fantastic job of most coffee varieties at a medium roast. Experiment to see which level of roast you prefer.

Additional roast profiles are available from our community pages. To start with there are only a few different profiles available, but this will change as more get added. Once you have found the profile you want, make a folder called /kaffelogic/roast-profiles on a USB memory stick. Download the roast profile file and save it in that folder. Then put the USB memory stick into the roaster and press the 'profile' button. This will let you load the new profile into the machine. Adjust the level, and you are ready to roast.

Development of additional specialised profiles is under way.

This interactive coffee taster's flavour wheel is a useful resource for those of you who are developing profiles.
