Matcha Whisk 101: Everything you need to know
A bamboo whisk (chasen) is the single most important tool for making matcha. Here's how to use it, care for it, and make it last.
What is a chasen?
A chasen is a traditional Japanese matcha whisk, carved by hand from a single piece of bamboo. The prongs are designed to blend matcha, water, and air together, creating a smooth, frothy texture with a clean aroma that no electric tool can replicate.
Our chasen has 100 prongs for the finest, most even foam. Prong counts vary across whisks (from 16 to 120), but 100 is the sweet spot for everyday matcha.
How to use it
- Soak your whisk in warm water for 1–2 minutes before each use. This softens the bamboo and keeps the prongs flexible. You may notice them gently fanning out — that's called "blooming" and it's completely normal.
- Sift 1 teaspoon (2g) of matcha into a bowl.
- Add 60ml of hot water (70–80°C, never boiling) and massage into a smooth paste with the whisk.
- Add another 60ml of water. Hold the whisk vertically from the top and move briskly in a W or M motion. Stay at the surface — no need to scrape the bottom. Use your wrist, not your arm.
- After 15–20 seconds a fine green foam will appear. That foam is what releases the aroma and softens any bitterness. That's when your matcha is ready.
Why a bamboo whisk and not a frother?
A chasen does something no electric tool can. It oxygenates the matcha as it blends, creating a fine foam that releases aroma and smooths out the flavour. That foam layer is what turns a decent matcha into a great one.
Electric frothers and blenders leave residual matcha unmixed and metal components can affect the taste. A chasen gives you the cleanest, smoothest result.
There's also something about making matcha by hand. Two minutes of slow, focused whisking. A small ritual that sets the tone for your day.
How to clean
Rinse your whisk in warm water immediately after each use. Swirl it gently in a bowl of warm water until no matcha residue remains. No soap needed — warm water does the job and is gentler on the bamboo.
After rinsing, gently reshape the prongs with your fingers if they've gathered together.
How to dry
Place your whisk on a whisk holder with the prongs facing down. This keeps its shape and allows air to circulate.
No holder? Stand it upside down on its handle with the prongs facing up. This works occasionally, but isn't ideal long-term as water can collect in the handle and encourage mould.
Never dry your whisk on its side. It will lose its shape quickly.
How to store
Always store your clean, dry whisk on a whisk holder. This protects the prongs and maintains the original shape.
Avoid storing in plastic containers or sealed boxes — trapped moisture leads to mould. Keep it in a dry, open space.
How long does a whisk last?
With proper care — soaking before use, rinsing after use, drying on a holder — a quality chasen lasts up to a year with daily use, and up to two years with lighter use.
You'll know it's time for a new one when the prongs start to break, thin out, or lose their shape.
