Sifting

Sifting means passing matcha through a tea strainer or small sieve before whisking, in order to break up clumps and help the powder disperse more evenly in water. Because matcha is an extremely fine powder, small lumps can form during storage or measuring, especially when humidity, static, or pressure is involved.

How sifting differs from milling and whisking

Sifting is not the same as milling. Milling is the process of turning processed tencha leaves into matcha powder. The term stone-milled matcha generally refers to a traditional method using stone mills, but sifting happens after the matcha has already been made, just before preparation. It is also separate from whisking, which combines matcha and hot water in the bowl.

Sifting belongs mainly to the preparation stage, not to cultivation or tea processing. ICHIZEN’s Kyoto Uji matcha is selected and refined by Wakimoto Jokoen and finished by machine into an ultra-fine, uniform powder. Even so, very fine powders are sensitive to handling after opening, so sifting can help make each bowl more consistent. For the role of powder fineness, see particle size.

In practice, place one serving of matcha in a dry strainer and gently press it through with a spoon or chashaku. The goal is to loosen compacted powder, not to grind it further. Make sure the strainer, scoop, and bowl are dry, since moisture can cause fresh clumping.

When clumps are reduced, the whisk can move through the tea more smoothly after water is added. This is useful for usucha, koicha, matcha lattes, and sweets. For the full preparation flow, see the step-by-step matcha guide.
