Matcha is finely ground powder of specially grown and processed green tea leaves, traditionally consumed in East Asia. The green tea plants used for matcha are shade-grown for three to four weeks before harvest; the stems and veins are removed during processing.

Hōjicha is a Japanese green tea. It is distinctive from other Japanese green teas because it is roasted in a porcelain pot over charcoal. It is roasted at 150 °C to prevent oxidation and produce a light golden colour, as opposed to other Japanese teas which are steamed.
