How to Choose a Matcha Whisk and Look After It

In short: for everyday matcha, choose a 100-prong bamboo whisk (chasen). It froths quickly, works for both thin usucha and lattes, and is easy to clean. Soak it in warm water for a minute before use, whisk in a fast "M" or "W" motion, rinse it in plain water afterwards and let it dry upright on a whisk holder.

A good whisk is the difference between a smooth, frothy bowl and a lumpy one. It is also the most delicate tool in your matcha kit. Here is how to pick the right one and keep it in shape through many months of daily use.

What is a chasen?

A chasen is a whisk carved from a single piece of bamboo. The top is split into many fine tines (prongs), which are thinned by hand and curled inward. When you whisk, the tines break up clumps of powder and fold air into the tea, giving matcha its creamy foam.

Metal whisks and electric frothers can mix matcha, but they do not create the same fine, even foam. Bamboo is also gentle on ceramic bowls.

Prong count: which one do you need?

Prong count is the number you will see most often. More prongs means finer tines and more air whisked into the tea.

For most people at home, 100 prongs is the sweet spot. Our Matcha Whisk is a traditional 100-prong chasen, the size we reach for every morning.

Shape, size and colour

• Shape. Most whisks have a rounded, bulb-like shape that suits usucha. Straighter, stiffer whisks are made for thick koicha.
• Handle length. A standard handle of about 10 to 11 cm sits comfortably in the hand. Shorter "travel" whisks exist but are fiddly.
• Bamboo colour. Pale white bamboo is the most common. Darker smoked or black bamboo is mainly a matter of taste; it does not change the foam.
• Bowl size. A whisk needs room to move. Use a wide bowl (chawan) about 11 to 12 cm across rather than a narrow mug.

How to whisk matcha properly

1. Soak the whisk. Stand the tines in warm water for 30 to 60 seconds. This softens the bamboo so the prongs flex rather than snap.
2. Sift the matcha. Sift 1 to 2 g (about 1 level teaspoon) into a warmed bowl to remove clumps.
3. Add water. Pour in 60 to 70 ml of water at 70 to 80°C. Boiling water makes matcha taste bitter.
4. Whisk from the wrist. Hold the whisk upright and move it quickly back and forth in an "M" or "W" shape for 15 to 20 seconds. Keep the tines just off the bottom of the bowl.
5. Finish the foam. Slow down, lift the whisk to the surface and make a few gentle passes to pop large bubbles. Lift it out from the centre.

Avoid pressing the whisk into the bowl or stirring in circles; that bends the tines and gives flat, bubbly tea. Good matcha makes whisking easier too: try Everyday Uji Matcha for lattes or browse our matcha powder range for ceremonial grades.

Cleaning and drying your chasen

Most whisks are ruined by how they are dried, not by how they are used.

• Rinse straight away in warm water. Whisk in a bowl of clean water for a few seconds to release powder from between the tines.
• No soap, no dishwasher. Detergent soaks into bamboo and leaves a taste; a dishwasher will warp and crack it.
• Shake, then air-dry upright. Gently shake off water and stand the whisk on a holder (kusenaoshi) with the tines down. This keeps the curl and lets air circulate.
• Never seal it away wet. Putting a damp whisk back in its plastic tube is the quickest way to get mould.

A Matcha Whisk Holder costs little and can double the life of your whisk. If you live in a damp flat or a hard water area, let the whisk dry fully in a well-ventilated spot rather than on a windowsill above the sink.

How long does a matcha whisk last?

With daily use and good care, a bamboo chasen usually lasts several months to a year. Signs it is time for a new one:

• Several tines are broken or have lost their inward curl.
• The foam is noticeably thinner even with good matcha.
• There are dark spots or a musty smell, which can mean mould.

A broken tine or two is normal and will not spoil your matcha. Snip any loose splinters off neatly so they do not end up in the bowl.

Frequently asked questions

Do I really need a bamboo whisk for matcha?

You can mix matcha with a spoon, a shaker or an electric frother, but a bamboo whisk gives the smoothest texture and the finest foam. For lattes, a frother is fine; for matcha with water, a chasen is worth it.

Why do I need to soak my matcha whisk?

Soaking in warm water softens the dry bamboo so the tines bend rather than break. It also helps the whisk move through the tea more smoothly. Thirty seconds to a minute is enough.

Can I wash a matcha whisk with soap?

No. Rinse it in warm water only. Soap gets into the bamboo, can leave a taste in your tea and dries the fibres out over time.

How do I stop my whisk going mouldy?

Dry it upright on a whisk holder, tines down, in an airy spot, and only store it once it is completely dry. Never put it back into its plastic case while damp.
