30-second summary

Matcha is Japanese green tea, shaded and then finely ground. We love it for its stable energy (caffeine + L-theanine), its silky texture and its umami umami. To enjoy it: choose a serious origindose 2 g for one usucha, work at 70-80 °Cand keep moderate depending on sensitivity.

What is matcha?

The word "matcha" (抹茶) means "ground tea". Unlike an infusion ingests the whole leafThe tea plant has been ground to a bright green powder. This is the heart of the Japanese tea ceremony - a precise, beautiful and humble skill.

How is matcha produced?

  • Shading 3-4 weeks before harvesting: this increases chlorophyll, L-theanine and caffeine.
  • Tencha transformation : destemming, drying, meticulous sorting.
  • Slow stone grinding The powder becomes silky, without heating up, which would burn the aromas.

Where do the best profiles come from?

Famous terroirs such as Uji, Nishio, Yame (Japan). Each origin has its own personality: more "noble seaweed" and cream, or more "hazelnut" and light cereal. At 94 Celcius, we start by selecting balance in a cup softness, length, absence of astringency.

What does it taste like?

A good matcha is a luminous green with hints of cream, kombu, toasted seedssometimes a touch floral. On the palate: a soft attack round bodya final umami.
