Matcha Grades Explained: From A to Ceremonial

The grading system for matcha can look confusing from the outside, with labels like AAA, 3A, 5A, 6A, ceremonial, culinary, and premium all appearing on different products. These labels are not governed by a single universal standard, which adds to the confusion, but they do follow general conventions that, once understood, make it much easier to know what you are looking at and what to expect from a given product.

How grading works

Matcha grading reflects the age of the leaf at harvest and the quality of the processing. Younger leaves from the tips of the shaded plant, harvested first in the spring, are the highest grade. They have accumulated the most L-theanine and chlorophyll during shading, they have the finest texture when milled, and they produce the smoothest, sweetest, most vibrant flavour. Older leaves, harvested later in the season or from lower on the plant, are used for culinary grades. They produce a more robust, earthier, more bitter powder that is better suited for blended applications.

The letter-grade system

The letter-based grading convention, where more A letters indicate higher quality, is commonly used but not standardised. AAA or 3A is typically a solid culinary grade. 5A is a premium or mid-ceremonial grade. 6A usually indicates a high ceremonial grade made from the most select first-harvest leaves. Some producers use different scales, so these labels should be read alongside the price, colour, and description rather than taken as an absolute measure.

Culinary grade in detail

Culinary grade matcha is made from older leaves with a stronger, more assertive flavour profile. Within culinary grade there are also quality levels, from basic culinary to cafe grade or barista grade, which refers to a culinary matcha specifically chosen to perform well in milk-based drinks. Barista grade culinary matcha typically has a stronger matcha flavour that holds up against milk without disappearing. Regular culinary grade is fine for baking and cooking. Barista culinary grade is the best choice for everyday lattes if you are not using ceremonial.

Ceremonial grade in detail

Ceremonial grade is a broad category that encompasses several quality levels. Standard ceremonial grade is made from young, spring-harvest shade-grown leaves and is smooth and pleasant for daily drinking. 

Premium ceremonial grades, including Uji grade and high numbered grades like 6A, come from specific premium growing regions or particularly select first-harvest leaves and exhibit the most complex, smooth, and naturally sweet flavour. For regular daily drinking, a solid standard ceremonial grade is perfectly appropriate. Top grades are for people who want the absolute best flavour experience.

What colour tells you

Across all grades, colour is a reliable quality indicator. Vivid, bright jade-green signals high chlorophyll content and freshness. A dull or yellowish-green can indicate lower quality, a later harvest, or oxidation from improper storage. The highest ceremonial grades have an almost electric brightness of colour. Culinary grades are slightly less vivid but should still be clearly green rather than brown or yellow.

Common questions

Why do different brands use different grade labels?  Because there is no globally enforced grading standard for matcha. Each producer uses their own scale. This is why colour, price, description, and brand reputation matter as much as the grade label.

Is 6A always better than 5A?  Within a single producer's range, yes. Across different producers, a well-sourced 5A from one brand may outperform a low-quality 6A from another.

Can I judge quality without tasting?  Colour is your best external indicator. Vivid jade green is a reliable signal of quality regardless of the grade label.
