Kaffelogic Nano 7 – coffee roaster for the kitchen counter
Load green coffee, choose a profile, press the button: in less than ten minutes, freshly roasted beans are in front of you. The Kaffelogic Nano 7 roasts 120 g per batch in a stream of hot air, on a footprint of 12.5 × 12.5 cm.
A fast PID controller guides the roast along a profile of time, temperature and airspeed. With the roast level you decide how light or dark the beans become. A higher level gives a darker, longer roast, a lower one a lighter, shorter roast. Kaffelogic designs and manufactures the roaster in New Zealand.
Features of the Kaffelogic Nano 7
Choose your own green coffee
If you roast yourself, you buy green coffee directly: individual farms, altitudes, varieties and processing methods. The Kaffelogic profiles are designed for different beans and brew methods; additional profile sets, for example by growing altitude, are available from Kaffelogic and the community.
Profiles with Kaffelogic Studio
The free Kaffelogic Studio software records every roast live when the roaster is connected to a computer via USB. You extract the profile from the log, adjust the temperature and airflow curves and load it back onto the roaster. Studio imports and exports Artisan and Cropster profiles, among others.
Even roasting in the air stream
In the fluid bed, the beans float on a column of air and are evenly surrounded by it. According to Kaffelogic, batch-to-batch repeatability matches that of commercial drum roasters. No reheating pause is needed between batches: after cooling, you can roast again straight away.
Sample roasting with plus and minus buttons
With the preloaded profiles, the Nano 7 also serves as a sample roaster. You extend or shorten the roast level before or during the roast directly on the unit with the + and − buttons.
The details in everyday use
Compact design
The Nano 7 needs no gas connection and no large exhaust system. Its slim, vertical design takes up little space and sits next to grinder, kettle and brewer. Kaffelogic recommends a well-ventilated location, for example next to an open window or under the range hood.

Who the Nano 7 is for
For everyone who wants to roast their own coffee: at home on the kitchen counter as well as in a roastery as a sample roaster. The preloaded profiles work without a computer, and Kaffelogic Studio opens up every parameter when you need it. How light or dark you roast is your call. There is no right and no wrong, the coffee has to taste good to you. Our opinion is one of many.
You will find everything from Kaffelogic in our Kaffelogic collection. After roasting comes the grinder: for everyone who wants to grind affordably and precisely, there are the Varia coffee grinders and the hand grinders from Comandante. If you want more, you will find the right grinders at Weber Workshops and Option-O. For weighing green coffee and brew water: compact and precise with Normcore, with app and flow-rate display with Acaia.
The advice tool narrows down which machine and which grinder suit your coffee. Delivery across Switzerland and to Liechtenstein in 2–5 working days, Click & Collect in Bern (Gerberngasse 44) and Zurich Oerlikon (Hagenholzstrasse 50b). Financing available.
Frequently asked questions
How much green coffee does the Kaffelogic Nano 7 roast per batch?
Kaffelogic specifies 120 g of green coffee per roast. With the optional BOOST Kit you choose the amount between 50 and 200 g in 10 g steps, depending on the coffee.
How long does a roast take?
According to Kaffelogic under 10 minutes, after which the roaster cools the beans in 2 to 3 minutes. No reheating pause is needed between two batches: after cooling, you can load the next batch straight away.
Do I need the software for the Kaffelogic Nano 7?
No. The roaster works independently with the preloaded profiles. The free Kaffelogic Studio software is for recording, adjusting and creating your own profiles and for updating the firmware.
Where is the best place for the roaster?
In a well-ventilated spot, for example next to an open window or under a range hood. Kaffelogic points out that the roaster may trigger a smoke alarm during normal operation.
Can I see the Kaffelogic Nano 7 before buying?
We are happy to check in advance by email at [email protected] whether the roaster is currently on display in Bern or Zurich. You can order directly online, with delivery across Switzerland and to Liechtenstein in 2–5 working days.
Tip from the roastery: If you are not roasting yourself in between, you will find freshly roasted beans from our coffee roastery in Zurich. For most people we recommend Cozy Chocolate and Nutty Delight: full-bodied, with chocolate and nut. Very Nutty brings maximum body without acidity. For the curious, Wild Peach is the fruity addition. You will find all varieties in our coffee beans. That is our recommendation, one of many.
