What Should Matcha Taste Like? What the Flavour Is Actually Telling You
Most people who try matcha for the first time and find it bitter assume it is just how matcha tastes. It is not. Bitterness in matcha is almost always a grade problem, a preparation problem, or both. A genuinely good first flush ceremonial grade matcha, prepared correctly, is smooth, naturally sweet, and layered in a way that takes a moment to fully register. Understanding what you are tasting, and why, is one of the most useful things you can develop as a matcha drinker.
What umami actually is
Umami is the fifth taste alongside sweet, sour, salty and bitter. It is the savoury, full-bodied depth that is difficult to describe but immediately recognisable once you know it. In matcha, umami comes primarily from L-theanine, the amino acid that accumulates in the leaf during shade-growing and reaches its highest concentration at first flush.
When you taste a well-made bowl of ceremonial grade matcha and notice a depth that lingers, a roundness to the flavour that does not fade immediately after you swallow, that is umami. It is not a green or grassy note. It is not sweetness. It is a fullness in the mouth that sits underneath everything else and gives the drink its character.
How first flush Yabukita produces it
Not all matcha produces umami in equal measure. The concentration of L-theanine in the leaf is determined by how the plant was grown and when it was harvested, and both of those factors are directly tied to first flush cultivation from a shade-grown, single cultivar plant.
Yabukita, the cultivar behind our Signature Ceremonial Matcha, is particularly responsive to shade-growing. When deprived of direct sunlight in the weeks before harvest, the plant overproduces L-theanine as a stress response. That accumulation is what produces the pronounced umami that distinguishes a first flush Yabukita from anything lower in the growing calendar.
By second flush, L-theanine concentrations have dropped noticeably. The umami fades with it. The flavour profile shifts toward more bitter, more astringent, less layered. It is still matcha. It is a fundamentally different drinking experience.
What a good matcha should taste like
A well-made first flush ceremonial grade matcha drunk in water, no milk, no sweetener, at the right temperature, should present in roughly this order.
Sweetness arrives first. Not sugar sweetness but a clean, natural sweetness that comes from the L-theanine in the leaf. It is present immediately and it should be notable.
Umami follows. The depth and fullness that gives the drink its body. This is what separates a good matcha from everything else. If the sweetness is there but the umami is absent, the leaf quality is lower than the label suggests.
A clean finish. Good matcha does not linger bitterly. It finishes cleanly, with the umami note fading gradually rather than being replaced by an unpleasant aftertaste. If the cup finishes bitter, the water was too hot, the matcha sat too long before drinking, or the grade is not what the label claims.
What happens to the flavour as matcha sits
This is worth understanding because it has practical implications for both how you drink matcha at home and what to expect when you order at a cafe.
Matcha is a suspension, not a solution. The particles disperse through the liquid when whisked but begin to settle almost immediately once whisking stops. Within ten to fifteen minutes, the suspension has started to break down. The flavour profile shifts. The umami note, which depends on an even distribution of L-theanine throughout the drink, flattens. The sweetness recedes. What remains is closer to a bitter green drink than the layered experience a properly prepared ceremonial grade matcha should deliver.
At thirty minutes, the difference is significant. This is why pre-batching matters. A matcha made to order and a matcha poured from a batch prepared an hour ago are not the same drink. The grade might be identical. The experience is not.
Why bitterness is almost never a preference
People who say they do not like matcha have almost always had matcha that was prepared incorrectly, sourced from a lower grade, or both. Bitterness is the most common complaint, and bitterness in matcha has specific causes.
Water that is too hot scorches the catechins and produces bitterness even from a high-quality leaf. The right temperature is 70 to 80 degrees celsius. Not boiling.
Lower grade or later harvest matcha has a higher ratio of catechins to L-theanine than first flush ceremonial grade. The bitterness of the catechins is not balanced by the sweetness and umami of the L-theanine. The result is a flat, bitter drink regardless of how carefully it was prepared.
Dairy milk, particularly cow's milk, binds to catechins and changes the flavour profile in ways that mask the umami entirely. What remains is a vaguely green, slightly sweet milk drink. If you have only ever had matcha with cow's milk, you have not tasted what matcha actually tastes like. Oat or plant-based milk lets the flavour come through without competing with it.
How to develop an educated palate
The most reliable way to understand what good matcha tastes like is to drink it in water first, at the right temperature, from a quality source. Everything else follows from that baseline.
Once you know what the umami should feel like, what the sweetness should taste like, and what a clean finish means in practice, you will notice immediately when those elements are absent. A flat cup, a bitter finish, a lack of depth. These are not subjective preferences. They are measurable indicators of grade, preparation and freshness.
Our Signature Ceremonial Matcha is Yabukita from Uji, first flush, shade-grown and JAS certified organic. Our Masters Reserve is Okumidori from Wazuka, the same standard with a deeper, more layered profile. Both are available in-store at our Sea Point cafe and online, delivered nationwide across South Africa.
