About the tea garden



20 ares.
Tea farm.

Matcha “Seian” (聖安) is one of the very few organically produced matcha teas that is suitable for use in the traditional service of thick tea. 


The producer of this tea works his approximately 20 ares of tea fields, situated in the outskirts of Uji, all by himself and by hand. Instead of relying on chemical fertilisers, he instead employs straw, fish rests and lees from rape seed as nourishment to imbue the tea with a delicious flavour, while tending carefully to the two layers of covering above the bushes, continuously adjusting the balance of shade according to the position of the sun.

In addition, since the use of chemicals and pesticides has been absolutely omitted, the farmer relies on his own eyes only to discover and remove larger bugs on the tea leaf. 

For the smaller bugs, he sprays the bushes with coconut oil as a repellant, and works with natural enemies of the bugs to safeguard the tea. For example, around the gardens sesame bushes keep bugs away, and those that do enter the gardens are sought out by the many frogs that live underneath the tea plants.
