Our Process:

Step 1

Source the Finest Tea

River & Stone works closely with the best natural farmers in Wazuka, Japan to source the highest quality tea leaves. Our farmers have standards higher than those for normal organic matcha, since they don't use pesticides, artificial fertilizers, or sprays of any kind.

A bowl of naturally-farmed tencha.

Step 2

Prepare the Tencha

We hold all of our tencha in cold storage here in Minnesota. When we need to use it, we carefully remove the stems and veins of the leaves, sifting them several times to ensure that only pure leaf material goes into our mill.

Step 3


We mill every tin of matcha to-order to maximize freshness. The mill only runs at about 40 grams per hour, making for a very laborious process. It is well worth it, as milling fresh matcha slowly ensures a very fine particle size and a greater range of aromatics in the finished tea.
