Why does my matcha taste powdery?
Updated By Mio.KBitter is a flavor. Fishy is a smell. Powdery is neither — it is something your tongue notices after you swallow, a fine chalky film that the next sip does not wash away. People describe it as sandy, grainy, or like drinking flour. It is worth separating from the other complaints, because the causes are different and so are the fixes.
Powdery matcha is almost never the tea. It is undissolved powder, and it comes from four things in this order: not sifting, water that was not hot enough, whisking that stopped too early, and drinking the bowl too slowly. Fix the first two and most of the grit is gone.
Start by deciding which problem you have
Taste it once more and ask where the sensation lives. If it is on the sides of your tongue and it is sharp, that is bitterness, and it usually means too much powder or water that was far too hot for the amount you used. If it is in your nose, like seaweed left in a warm room, the tin is old or it was stored badly. If it is on the flat of your tongue and it is dry and fine, that is powder that never went into the water.

1. You did not sift, and the clumps never opened
This is the cause I see most often, and it is the one people skip because it feels fussy. Matcha compacts in the tin. What comes out on the scoop is not loose powder but small dense lumps held together by static and pressure, and a whisk cannot open them. It drives them around the bowl, breaks them into smaller lumps, and those smaller lumps are what you feel at the end.
Ten seconds through a fine sieve is the whole fix. Press the powder through with the back of the scoop, straight into the bowl. If you want the long version, sifting matcha covers what a sieve does and what it does not do. A small tin sifter is one of the least expensive tools, and the one I would replace first if it vanished (how to use one).
2. The water was too cool
Cool water is the advice you will find everywhere, and it is given to protect the flavor. Taken too far it costs you texture. Powder disperses more readily in hot water than in warm, and if you pour at bath temperature you are asking the whisk to do work the water should have done.
I use water just off the boil, poured straight over the sifted powder. The bitterness people worry about comes from how much powder is in the bowl and how it is whisked, not from those last few degrees. There is a longer argument about this on the site, with the numbers the English-language guides quote: matcha water temperature.
3. You stopped whisking too early
Fifteen to twenty seconds sounds short until you actually count it. Most people stop at five or six, once the surface looks green and even. The powder is still in suspension at that point; it has not finished dissolving into the water, and it will settle out on the way to your mouth.
Whisk fast from the wrist in a W shape, keeping the tines just off the bottom, then one slow circle at the end to settle the foam. A whisk with enough tines does this in one go — a hundred-prong chasen moves far more water than an eighty. If the foam is what is bothering you rather than the grit, why matcha will not froth is the article for that, and how long to whisk matcha has the timings.
4. Too much powder for the water
Two heaped scoops of a bamboo chashaku is about 2 g, and 2 g wants 60 to 70 ml of water for thin tea. Push the powder up to 3 or 4 g without adding water and you are moving toward the density of thick tea, which is a different drink made a different way: usucha and koicha. Thick tea is meant to be dense. Thin tea made at thick-tea density just tastes like sediment.
5. The last mouthful, and how fast you drink
Here is the part the other guides leave out. Even a perfectly whisked bowl will drop a fine layer if you leave it sitting. Matcha is suspended, not dissolved — the particles are held up by the water and the foam, and gravity gets them in the end. A bowl you sip for ten minutes while answering email will finish gritty no matter what you did at the start.
Thin tea is made to be drunk in three or four mouthfuls, fairly soon after it is whisked. That is not ceremony for its own sake; it is the only time the bowl is what it was made to be. If you want something to hold for half an hour, make a latte, where the milk keeps the powder in suspension: how to make a matcha latte.
6. If it is still gritty, look at the powder
Only after the four above have been ruled out is it worth suspecting the tin. Real matcha is tencha milled to a flour so fine it clings to the side of a dry glass. Powder made from ordinary green tea is coarser, and no amount of sifting or whisking will make it feel like the other thing. If the grit survives a sieve, near-boiling water and twenty seconds of proper whisking, the powder is the problem: how to tell real matcha from green tea powder.
Questions I get asked
Why does my matcha taste powdery?
Because some of the powder never went into the water. Nine times out of ten it is a missing sieve or water that was too cool, and the remaining grit is whisking that stopped after five seconds instead of fifteen.
Does sifting really make a difference?
Yes, and it is the single biggest one. A whisk breaks clumps into smaller clumps; a sieve opens them. Ten seconds, every time, straight into the bowl.
Should the water be hotter or cooler to stop grittiness?
Hotter. Powder disperses better in hot water. I pour just off the boil and control the bitterness with the ratio and the whisking instead.
Why is there green sludge at the bottom of the bowl?
Matcha is suspended in water, not dissolved, so it settles. Drink the bowl within a couple of minutes of whisking and there is very little left to find.
Can a cheap whisk cause a gritty bowl?
It can. Too few tines, or stiff ones that have splayed with age, move less water and leave more powder behind. A hundred-prong whisk with the tines still curved does the work in about fifteen seconds.
Where this fits
The three things that decide texture are a sieve, water that is hot enough, and a whisk with enough tines: the sieve and the whisk are both in the complete set. If you are working out what you actually need before buying anything, start with the beginner's guide.
