Bamboo Scoop (chashaku)
Bamboo Scoop (chashaku)
The chashaku is the traditional bamboo scoop used to measure matcha — and the reason your matcha tastes consistent every time you make it.
This handmade bamboo scoop holds the right amount of matcha powder for a single serving. The ratio of matcha to water is one of the biggest variables in how matcha tastes, and eyeballing it rarely works. Too little and it's thin and grassy. Too much and it turns bitter and heavy. The chashaku removes the guesswork.
Lightweight, purpose-built, and carved from a single piece of bamboo. A small tool that makes a real difference to the daily ritual.
Also available as part of the Japanese Matcha Tea Set, which includes the bamboo whisk, ceramic bowl, and whisk stand.

Why measuring matcha properly changes the result
Matcha has a narrower margin for error than most drinks. The powder is concentrated — a fraction of a gram too much or too little shifts the flavour noticeably. A teaspoon is a rough approximation at best; its volume varies with how tightly the powder is packed. The chashaku is carved to a specific proportion that corresponds to roughly one serving of matcha, making it a reliable and repeatable measure every time.
For most preparations — a traditional bowl of matcha or a matcha latte — two level scoops (around 2g) is the standard starting point. From there, you can adjust slightly to taste. But starting with a consistent baseline is what lets you actually calibrate.
The traditional role of the bamboo scoop (chashaku)
In Japanese tea ceremony, the chashaku isn't just a measuring tool — it's considered one of the most personal items in a tea practitioner's collection. Traditionally carved from a single piece of bamboo or occasionally ivory, the scoop has been part of the matcha ritual for centuries. The version used today in daily matcha preparation is a direct descendant of that tradition, simplified for everyday use without losing its purpose.
Caring for your bamboo scoop (chashaku)
Wipe clean with a dry or barely damp cloth after each use. Avoid soaking in water or washing with soap — bamboo will crack or warp with prolonged moisture exposure. Store dry.
