Clumpy matcha is the most common frustration we hear about, and it is almost always fixable. Matcha is not a soluble powder. It is a suspension, which means the particles never truly dissolve, they hang in the water. Clumping is simply what happens when those particles are not given the chance to separate. Here is how we do it.
1. Start with matcha worth whisking
Fine, fresh, high quality powder suspends easily. Coarse or stale powder fights you no matter how good your technique is. Our Ceremonial Matcha is single origin, first flush, and stone ground fresh to order, which produces a particle fine enough to float rather than sink. If your matcha clumps every single time regardless of what you do, the powder is usually the reason.
2. Sift it first
This is the step people skip, and it is the one that matters most. Matcha is so fine that it compacts against itself in the tin and forms small tight clusters. Push it through a small fine mesh sieve into your bowl before any water touches it. A clump that has already formed in the powder will not break apart once it is wet, and no amount of whisking will save it.
It takes about ten seconds and it changes everything.
3. Use water at 175 degrees Fahrenheit
Boiling water scorches matcha. It pulls out bitterness and flattens the sweetness you paid for. We use water at 175 degrees Fahrenheit, which is hot enough to bloom the tea and cool enough to protect it.
If you do not own a temperature controlled kettle, boil your water and let it rest for about two minutes off the heat. That gets you close.
4. Whisk with a chasen
A chasen is the bamboo whisk carved from a single piece of bamboo, and there is no true substitute. Ours is imported from Japan with one hundred and twenty prongs, and those prongs are the entire point. They are fine enough and numerous enough to break the powder apart at a scale a spoon or a fork simply cannot reach.
Before you begin, soak the tips of your chasen in warm water for thirty seconds. This softens the prongs so they flex rather than snap, and it extends the life of the whisk considerably.
5. Make a paste before you make a tea
This is the technique that separates smooth matcha from lumpy matcha, and it is very simple.
Add only a small splash of your 175 degree water to the sifted powder. Perhaps two teaspoons. Then work the whisk slowly in small circles and press gently against the bottom of the bowl until you have a smooth, glossy paste with no dry pockets left in it. Take your time here. This is where the clumps are eliminated.
Once the paste is smooth, add the rest of your water, roughly two to three ounces for a traditional cup. Now change your motion. Whisk briskly in a light W shape or zigzag, keeping the whisk near the surface rather than scraping the bottom. Do this for about fifteen to twenty seconds, until a fine even foam forms across the top.
Do not stir in circles at this stage. Circular motion pushes the powder to the edges of the bowl. The zigzag is what builds the froth.
6. Care for your whisk
Rinse the prongs under cool water immediately after use. Never use soap and never put a chasen in the dishwasher. Set it prongs up to dry, ideally on a whisk holder, which keeps the bamboo curved outward as it dries and prevents the prongs from collapsing inward over time.
The short version
Sift the powder. Heat water to 175 degrees Fahrenheit. Add a splash and whisk to a smooth paste. Add the rest and whisk in a zigzag until foamy. Rinse the whisk and stand it up to dry.
