Matcha (抹茶 — ground tea) is powdered shade-grown green tea — tencha leaves that have been shaded from sunlight for three to four weeks before harvest (increasing chlorophyll and amino acid content, reducing catechin bitterness), dried without rolling, destemmed and deveined, then stone-ground to a fine powder at extremely low temperatures (preventing the volatile aromatic compounds from evaporating). The tea ceremony use of matcha in Japan was formalised by the monk Eisai, who brought the preparation from China in 1191, and standardised by Sen no Rikyu in the sixteenth century. The use of matcha in confectionery and patisserie — initially within Japan, globally from the 1990s onward — has transformed it from a ceremony object into one of the world's most versatile pastry flavouring ingredients.
For culinary use, matcha grade determines flavour. The grade system in Japan runs from ceremonial (ichiban-cha — first-flush, shade-grown, stone-ground, vivid green, intensely umami, expensive) through culinary (niban-cha or sanban-cha — later harvests, less shade time, more astringency, duller green, significantly less expensive) to low-grade culinary (used for colouring rather than flavour). Most matcha sold globally for baking is culinary grade. Most matcha used in high-end patisserie in Japan is ceremonial grade or premium culinary grade. The difference is visible (the colour deepens and brightens with quality) and flavourable (the amino acid l-theanine, responsible for umami and the calming effect of tea, is present in far higher concentrations in ceremonial grade).
1. Grade matters more for flavour than any other variable — a high-sugar preparation can be corrected with acid; an inferior matcha cannot be corrected with technique 2. Disperse before incorporating — never add dry matcha powder directly to fat 3. Acid destroys the colour — matcha and lemon are a flavour pairing that requires a choice: flavour or colour 4. Less sugar — matcha's bitterness is suppressed by sugar but not enhanced. Japanese matcha confections use less sugar than Western adaptations because the bitterness IS the flavour. Sugar balance should allow the bitterness to be present. Sensory tests: - **Colour check:** Ceremonial grade matcha at standard mixing: vivid, saturated jade green. Culinary grade: greener than grass, slightly yellow. Low grade: olive, khaki. The difference is visible in the dry powder before any preparation begins. - **Aroma check:** Open a container of high-grade matcha — the aroma should be simultaneously vegetal (fresh cut grass), marine (sea-like umami), and sweet (the l-theanine sweetness beneath the bitterness). If only astringency or bitterness is present, the grade is low. - **Flavour balance in a finished preparation:** A correctly balanced matcha confection should deliver bitterness first, sweetness second, and a lingering umami finish. If sweetness dominates, the matcha proportion was insufficient or the grade too low. If bitterness is harsh, the grade is too low or the sugar too little.
