Short answer: if you are whisking it and drinking it on its own, take a ceremonial grade. For baking and cooking, take a culinary grade. For lattes either works, and that is a matter of taste and budget rather than a rule.
The grades are not a legal standard
There is no authority that certifies what may be called ceremonial. One producer's ceremonial can be another's premium. What is behind the words is the leaf, and that is what to look at.
What actually differs
Ceremonial grades are made from the youngest leaves of the first harvest, shaded for weeks before picking, with the stems and veins removed before grinding. That gives a bright green powder, a sweet flavor and very little bitterness.
Culinary grades are made from later leaf. More body, more astringency, a duller green. That is not a downgrade, it is a different job. A culinary grade is built to hold its own against milk and sugar, which is what most lattes need.
Why the price differs so much
Only a small part of a harvest qualifies for the top of the range, and sorting it is slow work. Grinding is slow too: a stone mill produces a limited amount of matcha per hour, and finer grinding takes longer.
So the price difference is mostly about how little of it there is, not about a secret in the processing.
How to tell them apart without the label
Color is the clearest signal. A good ceremonial grade is vivid, almost fluorescent green. Culinary grades are duller and can tend towards olive.
Texture is the second. Finer powder feels almost like eye shadow between the fingers and clumps less.
And taste: if it is sweet and thick with very little bitterness, it is a high grade. If the bitterness arrives first, it is made for milk.
Which one for what
| What you are making | Grade |
|---|---|
| A bowl of matcha, whisked and drunk on its own | Ceremonial |
| Koicha, thick tea | Ceremonial, the highest you have |
| A latte, hot or iced | Either. Culinary is the value choice, ceremonial gives a sweeter, greener cup |
| Smoothies | Culinary |
| Baking, ice cream, chocolate | Culinary |
| A latte made with the highest grade | Not worth it. Milk covers what you are paying for |
| A gift for someone who drinks matcha | Ceremonial |
Ceremonial in a latte
Plenty of people use a ceremonial grade in milk, and there is nothing wrong with it. It gives a sweeter, greener, softer latte with less of the bitter edge that comes through from a culinary grade.
Whether that is worth the difference in price is your call. Make the same latte twice, once with each, and taste them side by side. Some people never go back to culinary; others cannot tell enough difference to justify it.
What we would not do is put the highest grade we carry in milk. At that level you are paying for a delicacy that milk covers up.
