Seeing Aroma — The Ko no Zu of Cacaogoto

Before chocolate reaches the mouth, the aroma arrives first.
In the moment you bring it close, something spreads — quietly shaping the expectation of what is about to be tasted.
Aroma is the entrance to flavor.
But aroma is invisible. It can be felt, yet resists words. When you try to share it with someone, something always remains unsaid.
The Ko no Zu — Cacaogoto's original aroma chart — was made to give that invisible thing a form the eye can follow.
A Hint from the Genji-Kō Diagram
In the traditional art of kōdō — the Japanese way of incense — there is a diagram called the Genji-kō-zu.
Kōdō, which took shape in the Heian period, does not use the word "smell" for encountering incense. It uses "listen" — monkō, or listening to fragrance. To turn toward aroma with the same quiet attention one might give to sound. That posture is the aesthetic heart of kōdō.
The Genji-kō-zu is a chart with fragrance names corresponding to each chapter of The Tale of Genji. It was used in a game called kō-awase, in which participants closed their eyes, listened to incense, and identified which chapter it belonged to.
An attempt by those who came before us to hold something complex and invisible within the clarity of a diagram.
The Cacaogoto logo was born from that inspiration. The letters of "CACAO" rendered in the form of the vertical lines of the kō-zu — layering the aesthetic of kōdō with a reverence for the aroma of cacao, within a single shape.
Two things born from entirely different worlds, resonating quietly in their shared posture: listening deeply to fragrance.
That is what the logo holds.
How to Read the Ko no Zu
The Cacaogoto Ka no Zu expresses the aroma of chocolate through six elements:
Floral, Fruit, Nut, Chocolate, Spice, and Acidity.
Each is rated on a five-point scale, represented by the length of a vertical bar.
The longer the bar, the stronger the aroma.
The more variation between bars, the more distinctive the character.
Elements of similar strength are connected by a horizontal line.
For a Tanzanian chocolate, for instance, the Acidity and Fruit bars extend long — and a vivid, lively aroma profile comes into view.
Depending on the farm, the fermentation process, or the roast, even the same origin can show an entirely different face.
This chart is not an answer. It is a first map — for discovering what kind of aroma draws you in.
Using the Ko no Zu
Place the Ka no Zu in your hands, and taste a piece of chocolate.
What had until then seemed vague suddenly begins to take shape.
"So this is what fruity means." "This acidity — it's so vivid."
Things that had no words slowly become visible. That moment changes the experience of tasting cacao, at a deeper level.
Cacao is said to contain more than a thousand aromatic compounds.
They differ by origin. They shift with the seasons. They show an entirely different character depending on what they are paired with.
That complexity and diversity — we invite you to verify it with your own senses.
Cacaogoto offers single-origin 100% cacao chocolates in the online shop. Whether whisked into Cacao Ippuku with a chasen, or tasted as they are — use the Ko no Zu as your guide, and compare the differences in aroma from one origin to the next.
