How to Adjust Light and Dark Roasts with Kaffelogic


With Kaffelogic, even with the same coffee beans, by changing the roast level, you can enjoy:
- Fruity and bright flavors
- Sweet medium roast
- Dark roast with a chocolatey feel
Here, we'll explain the basic adjustment methods for Kaffelogic.
STEP 1 | Turn on the power
Turn on the Kaffelogic.
STEP 2 | Select a profile
Press "Profile Selection" on the screen to display the desired profile.
This time, we will use
KL Explorer as our baseline profile.
STEP 3 | Adjust the roast level
Once KL Explorer is displayed, press the "+ / − buttons" on the unit to adjust the roast level.
How to interpret the levels
- Smaller number → Lighter roast
- Larger number → Darker roast
This is how it works.
Convenient Features of Kaffelogic
By performing this level adjustment,
based on the KL Explorer profile,
- Roasting temperature
- Roasting time
will be automatically adjusted.
In other words, a major feature of Kaffelogic is that you can change the roast level simply by adjusting the level, without having to make detailed changes to complex temperature settings.
Adjustable range
- Lightest setting → 0.1
- Darkest setting → 5.9
This is the range.
Recommended initial settings
Initially, we recommend trying:
- 1.5-2.0 → Lighter roast
- 2.5-3.5 → Medium roast
- 4.0 or higher → Darker roast
as a guideline.
Even with the same beans, simply changing the level can significantly alter the impression of aroma, acidity, sweetness, and bitterness ☕️
Adjustable even during roasting
With Kaffelogic, you can adjust the roast level even during roasting, while observing the beans' condition.
During roasting, by checking the:
- Bean color
- Aroma
- Smoke output
- Progression of cracking
you can immediately change the roast level by pressing the "+ / − buttons" on the unit.
For example, even if you feel:
- "I want it a bit lighter"
- "I want more sweetness or body"
- "I want to extend it a bit darker"
it's possible to make adjustments during the roasting process.
