Matcha milling


Have you seen how matcha is milled?  At Ocnha-no-sato tea museum, you can try milling *tencha into matcha. They give you a small pouch of tencha.  (Tencha is steamed and dried tealeaves, which is the ingredient of matcha.)     

You put tencha into a hole on the top of the stone mill.




Hold the handle and turn the mill slowly (about 1 turn in 1 second).  It is a little heavy, but turns smoothly with a comfortable sound.  You should not turn it too fast for good quality tea.


In a short while, you will find that green fine powders spill from the rims.


After several minutes of milling, you have a pile of matcha on the tray.  Then, the turning sound slightly changes, and you won’t find any more tea coming out of the slit. 


You can take your own milled tea home.


Matcha particle are about 1-20μ(micrometer).  The particles of fine quality matcha range 1-5μ.  Too high friction heat of milling can deteriorate the hue and flavor.  Stone is still the best material for the mill even in the modern time.  Auto-mills at tea factories also use stones.  Slowly turning the mill is nothing exciting, but it is a great experience to try actual matcha making^^

    1. The self milled tea was terrible(; ̄O ̄) It was so rough and bitter. I tasted the grains of tea. The cause could be the quality of ingredient, the mill or the way of milling. I assume that the mill is not good. I have seen someone’s blog saying that hand-milled tea he/she tried was excellent. So, I don’t think hand-milled tea is always bad.

    1. I have never tried it myself, but yes, it is said that milling speed affects the taste of tea.

  4. The European study showed that those who drank the tea lost more than those who dieted without the tea and they came to the conclusion that the antioxidants in the tea caused an increase in fat oxidation.

    1. I’m sorry that I don’t know any shop that sells stone mill to overseas. You should look for the stone mill that is meant for matcha. It should be finer than the ones for wheat. The particles of matcha are 1 – 20 micron. Good matcha has around 1 -5 micron particles. The unit that I found on the internet is about 200,000yen. It is quite expensive, isn’t it?
