How to roast

This page explains the basic way to roast coffee using the Kaffelogic Nano 7. The operation is very simple. Let's try roasting by referring to this first.


Setup Instructions

  • Place the unit in a well-ventilated area (e.g., near a window or under an extractor fan).
  • Place the unit on a stable, flat surface.
  • Ensure sufficient space around and above the main unit.

Also, the main unit has a structure through which air flows. Please be careful not to block the intake and exhaust parts with a tablecloth or cloth.


STEP 1 | Weigh the green beans

The Kaffelogic Nano 7's default setting uses 120g of green beans. We recommend starting your roast with 120g as a benchmark.

 

STEP 2 | Load beans and attach the chaff collector

Add the weighed green beans to the roaster. Then, securely attach the chaff collector from the top. Make sure the lid is properly seated.


STEP 3 | Perform Fan Preview

Fan Preview is a function to check the circulation of beans before roasting.

With 120g of beans loaded, press the "≡ (Menu)" button on the right side of the unit and select "Fan Preview."

The fan will activate, and you can observe the movement of the beans.

Specifically,

  • Are the beans circulating gently as a whole?
  • Are the beans in the center slowly being replaced?

Please check.

Performing a Fan Preview correctly will:

  • Prevent thermal runaway
  • Reduce uneven roasting
  • Improve roast repeatability

This will lead to.

 


STEP 4 | Power On

Once you have confirmed the bean circulation with Fan Preview, next select a roasting profile.

For your first roast, we recommend "KL Explorer", Kaffelogic's standard profile. KL Explorer is an all-around standard profile compatible with a wide range of coffee beans. Start by using KL Explorer to experience basic roasting with Kaffelogic.

STEP 5 | Start Roasting

Press the ▶ button to start roasting. Roasting proceeds automatically, but for safety, do not leave the area during roasting.


During Roasting

Kaffelogic automatically controls temperature, time, and airflow. Generally, you just need to monitor it.


After Roasting | Cooling and Removing Beans

When roasting is complete, the machine automatically begins to cool down. After the cooling is completely finished, remove the chaff collector and take out the roasted beans. Check that no beans remain in the roasting chamber and gently shake if necessary.


Enjoying Your Roasted Coffee

Freshly roasted beans contain a lot of gas (CO₂) inside.

Hot-air roasters like Kaffelogic circulate beans with strong hot air during roasting,
making it less likely for smoke and gas to accumulate, and resulting in a relatively cleaner finish.

Therefore, compared to general roasters, the flavor of freshly roasted coffee can be perceived as developing faster.

Please enjoy the fresh aroma and changes in taste unique to freshly roasted coffee. Also, by letting it rest for about 1 to 2 days, the flavor may gradually settle, and the sweetness and balance may become more noticeable.


Next Steps

  • Enjoy the difference in taste between light and dark roasts by changing the level.
  • Try a different profile.
  • View roast logs in Kaffelogic Studio.

There is no "right answer" to roasting. Please find the taste that suits your preference.
