Common Matcha Preparation Mistakes

The most common mistake, and the most fatal. Boiling water scalds the leaf and pulls the bitter compounds out ahead of the sweetness — the cup turns harsh no matter what you did right.

The fix: 70–80 °C. Boil the kettle and let it rest, lid open, about four minutes. Your matcha will taste sweeter tonight than it has all year.

Unsifted matcha clings to itself in microscopic clumps that survive the whisk and burst bitter on the tongue. It looks like fussiness and isn't — it's the difference between silk and sand.

The fix: ten seconds through a fine mesh sieve, pressed with the back of the scoop, before any water arrives.

Circles move clumps around the bowl without breaking them. A spoon stirs but never whips. Either way you get flat, thin tea with a few sad islands.

The fix: a bamboo chasen, held lightly, stroked in a brisk M or W — wrist still, arm doing the work — until a fine foam covers the surface.

“About a spoonful” drifts a little more each day, and the bowl drifts with it: too much powder turns thick and harsh, too little turns thin and hollow.

The fix: 2 g per 70 ml — two level bamboo scoops or one level teaspoon. Measured, leveled, done.

Light, heat, air and time oxidise matcha — the jade fades toward olive and the cup turns flat, then bitter. Powder doesn't spoil so much as it quietly retires.

The fix: airtight, cool and dark; finished within a few weeks of opening. Buy the tin size you'll actually drink.

Stale matcha can't be fixed — but it can be prevented, and it makes a fine addition to smoothies.
