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
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.
Fan Preview
Fan Preview is a function to check the circulation status of beans before roasting. It does not heat, but only activates the fan to check the movement of beans inside the roasting chamber.
To operate, simply access it from the "≡ (Menu) button" on the main unit.
Why Fan Preview is important
In Kaffelogic, one of the crucial factors influencing roast quality is "proper bean circulation."
Normally, the fan is automatically controlled based on calibration, but:
- Differences in bean density
- Changes in batch size (input amount)
can sometimes prevent ideal circulation. By using Fan Preview, you can check the status before roasting and make adjustments as needed.
How to check bean circulation
- Weigh 120g of green beans and load them into the roaster.
- Attach the chaff collector.
- Select the K-logic Classic profile.
- Press the "≡" button.
- When "Press ⏵ now for fan preview" is displayed, press the ⏵ button.
→ The fan will activate. - The display will show "120g" and "14700 rpm". If not displayed, adjust to these values using the + / - buttons.
- Check the bean circulation status.
Ideal fan level
- Ideally, the beans should circulate gently.
- Pay particular attention to whether the beans in the center are slowly rotating and exchanging positions.
Fan level is too strong
Fan level is insufficient
How to handle strong or weak bean circulation
If you are not getting sufficient circulation, please follow the steps below to adjust.
Adjust light and dark roasts
Same beans, different taste.
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.
Roast lightly.
With Kaffelogic, you can record the "Color Change" and "First Crack" timings that occur during roasting directly from the unit.
These records are useful for adjusting profiles and analyzing roasting results.
Recording Color Change
When the beans start to change color during roasting, perform the following steps:
- Press the "≡" (three lines) button on the unit.
- Press the "－" button to display "Color Change".
- Press the "▶" button.
This will record the color change timing.
Recording First Crack
When the first crack begins, perform the following steps:
- Press the "≡" (three lines) button on the unit.
- Press the "▶" button.
This will record the first crack timing.
Utilizing the Records
By recording the timing of color change and first crack, you can adjust your roast profile while comparing it to the actual bean reaction.
Please use this feature when repeatedly roasting the same beans or when creating new profiles.
How to Check Recorded Timings
When you record Color Change and First Crack, you can check them on the Studio graph after roasting.
On the profile, the predicted timings for Color Change and First Crack are displayed. The timings actually recorded during roasting are also displayed on the graph, allowing you to compare the profile's predictions with the actual roasting results.
- Left yellow vertical line: Predicted timing of Color Change
- Right dark yellow vertical line: Predicted timing of First Crack
- Triangular marks on the graph: Actual recorded timings of Color Change and First Crack during roasting
By comparing predicted and actual values, it becomes easier to understand the differences between the profile and the bean's reaction.
Please use this information as a reference when you want to improve the reproducibility of the same beans or when creating new profiles.
DTRを調整する
DTR（Development Time Ratio）とは、ハゼ（First Crack）が始まってから焙煎終了までの時間が、 焙煎全体に対してどの程度の割合を占めているかを示す指標です。
DTRを調整することで、浅煎りから深煎りまで焙煎度合いをコントロールできます。
DTRの目安
一般的な目安として、以下のようなDTRが参考になります。
- 浅煎り：15〜18%
- 中煎り：18〜22%
- 深煎り：22%以上
※豆の種類や好みによって最適な値は異なります。あくまで参考値としてお考えください。
KaffelogicでのDTR確認方法
焙煎中にハゼ（First Crack）を記録すると、表示画面が切り替わり、 現在のDTRがリアルタイムで表示されます。
この数値を見ながら、浅煎り・中煎り・深煎りのどの焙煎度合いにするかを判断できます。
焙煎を早めに終了する
予定より早く焙煎を終了したい場合は、以下の操作を行います。
- 「▶」ボタンを押す
- 続けて「－」ボタンを押す
この操作を行うと、その時点で焙煎を終了できます。
さらに焙煎を進める
多くのプロファイルでは、あらかじめDTRが設定されています。 例えばDTRが15〜18%程度に設定されている場合、 その値に到達すると自動的に焙煎が終了します。
しかし、実際の豆の色や香りを確認しながら、 「もう少し焙煎を進めたい」と感じる場合もあります。
その場合は「＋」ボタンを押してください。
焙煎終了時間が延長されるため、 豆の状態を確認しながら手動で焼き加減を調整できます。
プロファイル作成への活用
焙煎終了後はログ画面から、 ハゼが始まった時間や最終的なDTRを確認できます。
実際に好みの味になった焙煎結果を記録しておくことで、 次回以降のプロファイル作成や調整に活用できます。
DTRは焙煎の再現性を高めるための重要な指標です。 ぜひ記録を取りながら、自分好みの焙煎を見つけてください。
