Matcha green tea is a finely ground powder made from young, specially grown green tea leaves.
Green tea (even powdered green tea) may be grown in China, Japan, and several other surrounding countries–however, true matcha is grown using a different method and is only grown in Japan.
While standard green tea is grown in the sun and includes the veins and stems of the leaf, matcha green tea is grown mostly in the shade, de-stemmed and de-veined, and stored in darkness for several months to cultivate and preserve the flavor and health benefits.
Matcha is higher in caffeine because the immature tea leaves used to make it contain more caffeine than the mature leaves in regular green tea.
