Option: Ready-to-Drink Roasts

Normally, freshly roasted coffees have to rest (degas) for a few days after roasting before they are drunk. This is basically also the case with the Kaffelogic Nano 7e.
However, the type of heat transfer also allows for ready-to-drink roasting, in which the coffee can be drunk immediately after roasting. Kaffelogic provides specific roasting profiles for this. 


New Chaff Collector

From the end of November / beginning of December 2022, Kaffelogic will offer a new Chaff Collector with glass as an accessory, through which the roasting process can be easily observed. The new Chaff Collector is included in the order of the Kaffelogic Nano 7 with cable connection (currently, the units are still delivered with the old Chaff Collector, the new one will be delivered later). For older units, the new Chaff Collector can be ordered as an accessory:

The new Chaff Collector is simply placed on the unit instead of the old one, no technical knowledge or conversion work is required.



From the end of November / beginning of December 2022, Kaffelogic will offer the so-called BOOST Kit as an accessory, with which you can roast 50g to 200g of green coffee.

USB / cable connection

In the previous version of the Kaffelogic Nano 7, log files and profiles were exchanged between the computer and the roaster using a USB stick. In this version, the files are transferred via a cable.

Hervorragender Röster. Einfach in der Handhabung..

unkomplizierter Sample Röster, mit dem man schon nach kurzer Zeit sehr gute Röstergebnisse erzielt. Er gibt einem auch die Möglichkeit sehr detaillierte Einstellungen vorzunehmen, so kommt der Spaß am Experimentieren auch nicht zu kurz.
Shop bietet sehr guten Service, auch dank Herrn Albrecht.

Sehr gutes Einsteigergerät zur Kaffeeröstung. Oder als Standardheimgerät. Einfache Bedienung und tatsächlich doch viele Möglichkeiten. (Quelle: SHOPVOTE)

Mein erster Röster. Für mich ein einfacher Start ins Heimrösten. Zusammen mit den YouTube Videos der Roasrebels bin ich frustfrei zu den ersten gut trinkbaren Ergebnissen gekommen. Danke dafür! Nun stehen mir die umfangreichen Möglichkeiten über die Software zu experimentieren offen. Mal sehen, was da aus den Bohnen noch so raus zu holen ist...
Shop-Qualität und Versand sind makellos. (Quelle: SHOPVOTE)

Top-Shop - Top-Gerät!

Ich habe das Gerät - nach netter Kommunikation mit Herrn Albrecht und nachfolgender Bestellung - gestern bekommen und gleich nachmittags eine Röstung mit Ready-to-Drink-Profil (1500-2000m) vorgenommen. Nach erster Verkostung eines Honduras Highland (SHG) am heutigen Morgen (Vollautomat) kann ich Folgendes sagen: Ich hatte hohe Erwartungen, und wenngleich der Röstgrad mit 4.5. noch klar zu hoch gewählt war, ist absehbar, dass da einiges geht mit der Maschine. Ich werde in der kommenden Zeit zunächst die Standardprofile ausprobieren, besonders hinsichtlich des für mich passenden Röstgrades, und dann versuchen, mit Hilfe von Kaffeelogic Studio (Software) für verschiedene Rohkaffees angepasste Profile zu entwickeln. Ich bin schon jetzt davon überzeugt, mit dem Nano 7e den für mich passenden Röster gefunden zu haben.

2 Mar 2022

Nach meinen ersten...

Nach meinen ersten Röstversuchen kann ich nur sagen, dass meine Erwartungen voll erfüllt wurden.
