- Description
Hekisui (碧翠) - "Jade Green" - is a ceremonial matcha from Heikisuien, Joyo, Uji, Kyoto, built on a Midori, Asahi, and Uji Hikari blend. It is the most unusual matcha in the Heikisuien koicha range: light, creamy, and airy despite its high umami - a combination that makes it one of the most elegant thick-preparation matchas in the Chaseki portfolio. Chaseki was the first to introduce Heikisuien matcha to Thailand in 2021. Hekisui is the one that defies the expected weight of koicha.
About Hekisui
Hekisui is part of our Ceremonial Matcha collection and is produced by Heikisuien in Joyo, Uji, Kyoto. The name Hekisui (碧翠) translates as "jade green" - a name that captures its luminous color and clean, precise character.
Three cultivars compose the blend: Midori, which brings structural lightness and an airy, clean quality; Asahi, which adds its characteristic buttery body and creamy mouthfeel; and Uji Hikari, which contributes deep umami, natural sweetness, and the long, persistent finish that makes this matcha perform in koicha.
The result is a matcha that holds a tension worth experiencing: high umami from Uji Hikari, Asahi's rich body, but Midori keeping the whole composition feeling light, airy, and refined rather than dense. In a category dominated by heavy, coating cups, Hekisui is different.
Taste Profile
Mouthfeel: Medium to thick, light and airy Finish: Long Umami: High Sweetness: Natural, clean Flavor NotesHekisui opens with a medium to thick body that feels surprisingly light and airy on entry - clean and precise rather than heavy. Hints of buttered green peas and asparagus lead the vegetal character, fresh and direct. Natural sweetness builds across the mid-palate, paired with pleasant buttery and nutty notes of macadamia. A slightly floral quality emerges - hints of roses, osmanthus, and vanilla add a delicate aromatic layer without weight. Strawberry fruit notes arrive lightly at the back palate, adding a subtle brightness. High umami sustains throughout, clean and integrated, confirming the depth that Uji Hikari delivers. The finish is long and gently sweet. A cup that is harder to describe than it is to appreciate.
How to Use Hekisui
Best suited for:- Koicha
- Usucha
- Clear-style preparations
Hekisui is recommended for koicha. Despite its light, airy character, the high umami, Asahi creaminess, and Uji Hikari depth all hold up under thick preparation - the lightness becomes an asset, keeping the cup elegant rather than heavy under concentration. In usucha, it produces a bowl of notable refinement. Step below to Ukitsu for more pronounced floral sweetness. Step above to Houju for the richest, most complex expression in the Heikisuien koicha range.
How Hekisui Compares
Hekisui sits at the higher middle of the Heikisuien koicha range. Below it, Shien and Ukitsu are richer and heavier - Shien with cooked pea depth and dark chocolate, Ukitsu with pear sweetness and vanilla florals. Above Hekisui, Houju is the pinnacle of the range: richer, more complex, with yogurt creaminess, jasmine, and the highest umami of all four. Hekisui's position is defined by its unique light-yet-deep character - more complex than Ukitsu in umami depth, but lighter in body than Houju.

Frequently Asked Questions
What does 'light, creamy, and airy' mean for a koicha matcha?
Most koicha matchas are dense and heavy - concentration amplifies weight. Hekisui is different. Despite its high umami, the Midori cultivar produces a lighter, airier texture that makes thick preparation feel surprisingly elegant. The creaminess comes from Asahi. The depth from Uji Hikari. But the overall character stays light.
What is the Midori cultivar?
Midori is a Japanese tea cultivar valued for its clean character, lighter mouthfeel, and bright, airy quality. In Hekisui, it provides the structural lightness that prevents Asahi's richness and Uji Hikari's depth from becoming heavy. An unusual and distinctive balance for a koicha matcha.
How does Hekisui compare to Ukitsu?
Ukitsu (Samidori + Asahi) is sweeter and more pear-forward - roses, osmanthus, vanilla dominating. Hekisui is lighter in texture but higher in umami, with floral notes alongside macadamia nuttiness and strawberry fruit. Ukitsu is the sweeter, more romantic cup. Hekisui is more complex and umami-forward.Is Hekisui suitable for koicha?
Yes. Despite its light character, Hekisui's high umami, Asahi creaminess, and Uji Hikari depth hold up under thick preparation. The Midori lightness keeps the koicha cup elegant rather than heavy.
What is the difference between Ceremonial, Daily, and Latte Matcha?
Ceremonial is for usucha and koicha. Daily is for regular enjoyment. Latte is for milk-based preparations.
Is this matcha suitable for beginners?
