Real Matcha vs Green-Tea Powder: How to Tell

Not every green powder is matcha. The differences are in shading, de-veining and milling.

True matcha starts as tencha: leaves shaded for weeks, steamed, dried flat without rolling, then de-stemmed and de-veined before milling. Imitation 'matcha-style' powders are usually unshaded sencha or bancha leaves milled whole, stems included — cheaper, yellower, coarser and more bitter. Clues: real matcha is vivid green and very fine (around 5-10 microns for stone-milled), foams readily, and its ingredient list says tencha or matcha, not 'green tea powder'. Country of origin and harvest season on the label are also good signs.
