The grinding of Matcha

The last step in producing Matcha takes place in the factory where special granite stone mills grind Tencha tea into superfine Matcha powder.

The grinding itself is done in a cleanroom in which temperature and humidity are kept constant. Industrial quality filters keep the air clean and eliminate bacteria and germs.

Can you imagine how fine a grain of Matcha powder is? An average single mini powder grain measures only 5-10 microns – tiny when you consider that a micron is one millionth of a meter. This is so ultra fine that the powder just melts in the mouth. One single stone mill grinds only up to 30-40g tea per hour, which is basically the amount of one Matcha tin.

Even in the 21st Century the granite stone mill is still necessary to make Matcha out of the very sensitive Tencha tea leaves. Only this method ensures that the tea retains its intense colour and exquisite taste and flavour.
