What is Tencha? The “Soul” Before It Becomes Matcha
Tencha (碾茶) is the raw material of matcha—essentially, the tea leaves before they are ground into powder.
Only when Tencha is ground by a stone mill or a ball mill and sieved to a particle diameter of D60 ≤ 18 microns does it officially become the Matcha we know and love.
