What Does Ceremonial Grade Matcha Mean? A Producer's Perspective in Japan

If you have spent any time shopping for matcha, you have almost certainly encountered the phrase "ceremonial grade." It appears on tins, in product descriptions, and across social media, often positioned as a shorthand for the highest quality matcha available. In many cases, it can be a useful signal. 

But it can also be a confusing one.

“Ceremonial grade” is not a regulated classification. There is no governing body in Japan or elsewhere that certifies matcha as ceremonial. The term emerged in the early 2000s as matcha entered Western health-food and specialty-tea markets. At the time, importers needed a simple way to communicate quality to consumers unfamiliar with Japanese tea culture.

Understanding what separates genuinely excellent matcha from a label on a tin requires looking beyond the grade and into the process and intentionality of how matcha is made. 

As we represent historic, heritage Japanese tea producers who have been making tea for over centuries, we want to share what our farm and producer partners look at when evaluating quality, and what we think you should look at, too.

How Does Japan Evaluate Matcha Quality?

In Japan, matcha is not sorted into “ceremonial” and “culinary” bins. Instead, each tea is evaluated across a spectrum of characteristics, and its intended use follows from those qualities rather than the other way around.

The factors Japanese producers consider to designate truly exemplary tea include the harvest season (first flush is the premier, subsequent harvests can indicate lower grades), the duration and method of shade-growing, the age and cultivar of the tea plant, whether stems and veins have been removed before milling, and the milling process itself. 

A matcha destined for use in the tea ceremony, where it will be whisked purely with water and nothing else, must perform at the highest level across all these variables. A matcha intended for confections or blending into lattes can be more forgiving.

Within the tea ceremony tradition, matcha is described by its preparation style rather than by grade. Koicha, or thick tea, requires an exceptionally refined matcha with deep umami, minimal bitterness, and a smooth, almost syrupy body. Usucha, or thin tea, is the more common daily preparation and is somewhat more flexible. Koicha is considered the pinnacle experience of the tea ceremony. According to Mizuba colleagues in Japan, a tea that can be enjoyed in its purest form when whisked as koicha could be considered ‘ceremonial.’ Both koicha and usucha point to a far more nuanced way of thinking about quality.

What Makes Matcha High Quality?

If the label alone cannot tell you everything, what can? We evaluate matcha the same way our producers in Uji, Shizuoka, and Yame do, and these are the qualities that matter most.

Shade-Growing Changes Everything

The single most important factor in matcha quality is shade-growing. Roughly twenty to forty days before harvest, tea fields are covered with shading structures. These are traditionally woven bamboo reeds, and tea grown under these rare wara coverings is usually reserved for competition. More commonly, you’ll find suspended tarps, called tana, that block up to 90% of direct sunlight.

Inhibiting photosynthesis changes the plant's chemistry profoundly. Without adequate sunlight to fuel photosynthesis at its normal rate, the tea plant retains higher concentrations of L-theanine, the amino acid responsible for matcha's characteristic umami sweetness and its calm, focused energy. 

In an unshaded plant, sunlight converts L-theanine into catechins, which contribute bitterness and astringency. Shading slows that conversion, preserving sweetness while the plant also produces more chlorophyll to capture whatever light reaches the leaves. That increased chlorophyll is what gives high-quality matcha its vivid, almost electric green color.

A peer-reviewed study published in Molecules confirmed that shade-growing significantly increases both theanine and chlorophyll content in tencha leaves while decreasing the polyphenols responsible for bitterness.

Place a matcha made from properly shaded tencha next to powdered sencha (milled from sun-grown leaves), and the contrast in color, aroma, and taste is unmistakable.

Harvest Timing

The first harvest of the year, called ichibancha, occurs in late April through mid-May. These are the youngest, most tender leaves at the top of the plant, and they carry the highest concentrations of L-theanine and the most delicate, complex flavors. Each subsequent harvest produces leaves with lower amino acid content, higher catechin levels, and a correspondingly more astringent, less nuanced cup.

Exceptional-quality matcha is made from first-flush leaves. Culinary matcha often draws from second or later harvests, which is perfectly appropriate for recipes where the matcha will be blended with milk, sugar, or other ingredients. The distinction is functional, and while there certainly is a range of quality ‘culinary’ matcha teas, we like to consider the category and its use case when used for its intended purpose.

From Tencha to Powder

True, authentic matcha must be made from tencha, a specific preparation of shade-grown tea leaves. After harvest, tencha leaves are steamed to halt oxidation, dried in specialized brick ovens called tencha-ro, and then destemmed and deveined. What remains is the pure leaf material, ready for milling.

Milling is where patience becomes tangible. Traditional granite stone mills turn slowly, producing roughly 30 to 40 grams of matcha per hour. That is about one tin. The slow speed prevents heat from building up during grinding, which would damage the tea's color, aroma, and amino acid profile. The result is an ultra-fine powder with a particle size small enough to suspend in water and produce the smooth, creamy body that defines well-made matcha.

\ Lower-cost matcha is produced using faster mechanical methods, such as bead mills and jet mills, which can generate more heat and result in a coarser texture. These methods are not inherently bad, but they do produce a different sensory experience, and you will notice the distinction in the cup.

The Color, Aroma, and Taste of Quality

You do not need laboratory equipment to assess matcha quality. Your senses can be remarkably reliable guides.

1. Color is the most immediate indicator. High-quality matcha is a vibrant, saturated green. Dull, grey, or yellowish matcha suggests insufficient shading, older leaves, or degradation from improper storage or processing. When you open a tin of well-made matcha, the green should feel alive.

2. Aroma reveals the next layer. Quality matcha carries a sweet, almost marine-like fragrance, sometimes described as the "shade aroma" or ooika in Japanese. This scent comes from dimethyl sulfide, a compound that develops during extended shading. If the matcha smells flat, dusty, or overly grassy, the shading or processing likely fell short.

3. Taste tells the full story. A well-made matcha opens with umami, the savory-sweet depth that L-theanine produces. There may be a pleasant, balanced bitterness (what Japanese tea professionals call shibui, a refined bitterness that adds character), but it should never be sharp or lingering. The finish should be clean, smooth, and inviting enough that you want another sip.

Ceremonial and Culinary Refer to Different Tools Rather Than a Hierarchy

One of the more common misunderstandings about matcha grades is that culinary matcha is simply bad matcha. Often, it is. There is a lot of culinary matcha on the market that has contributed to this reputation. But “culinary” was never meant to mean low quality. It was meant to signal a matcha built to hold its own against milk, heat, sweeteners, and other ingredients, something ceremonial grades aren't designed to do. That's why we don't carry a "culinary" line anymore. Instead, we recommend our Signature Matcha as our most refined choice for lattes and blended drinks. It's built for the job culinary grade was supposed to do, without the compromise in quality the name has come to imply.

Asking which is better is like asking whether a chef's knife is better than a paring knife. Each one excels at what it was designed for.

We carry a range of matcha teas across this spectrum. Our Daily Matcha and House Matcha are technically ceremonial-grade teas, made from first-flush tencha and stone-milled in Uji, but we position them as approachable everyday matcha because we think the best matcha is the one you actually reach for each morning. 

Our single-cultivar teas like Okumidori and seasonal offerings reflect the higher end of the spectrum, where cultivar, terroir, and the producer's craft converge in ways that reward careful, traditional preparation.

What Should You Look for When You Are Buying Matcha?

Rather than relying on a grade label alone, we encourage asking a few straightforward questions.

• Is it made from tencha? Genuine matcha is made from shade-grown tencha leaves. Matcha made from sencha or other sun-grown leaves will taste more bitter and lack the amino acid depth that defines the style.

• Is it stone-milled? Traditional stone milling produces the finest particle size and the smoothest cup. It is also slow and expensive, which is part of why quality matcha costs what it does.

• Is it from the first harvest? First-flush leaves carry the most L-theanine and the most complex flavor. This matters most for matcha you plan to drink on its own.

• Can the seller tell you where it comes from? Origin transparency is one of the clearest signals of quality. A company that can name the region, the producer, and the cultivar has a relationship with its source. A company that cannot may be buying commodity matcha and putting a label on it.

These questions will tell you far more than "ceremonial grade" ever could on its own.

Why Do We Still Use the Term Ceremonial?

Given all of this, you might wonder why Mizuba uses the phrase "ceremonial grade" at all. The honest answer is that it serves a real purpose for people who are navigating a crowded market and looking for a starting point. When we describe a matcha as ceremonial, we mean it meets a specific set of standards: first-flush tencha, shade-grown in Uji, stone-milled, and refined enough to drink with water and nothing else.

We pair that label with the transparency to back it up. We can tell you which farm produced each tea. We can describe the cultivar, the harvest conditions, and the processing decisions that shaped the final product. The grade is the introduction. The details are the substance.

Taste the Difference for Yourself

Reading about matcha quality is valuable, but tasting it is where the understanding deepens. 

Prepare a bowl of matcha. Pay attention to the color in the bowl, the aroma rising from the surface, and the first taste on your palate. Notice whether the umami arrives before the bitterness, whether the finish is clean or astringent, and whether the texture feels silky or grainy.

This is what ceremonial grade is supposed to be. It is a matcha that is complete on its own, a tea that has been shaded, harvested, processed, and milled with enough care that it needs nothing added to be worth your full attention.
