The Perfect Sencha Water Temperature (煎茶の淹れ方とお湯の適正温度 - Sencha)
The fundamental temperature rule for brewing standard Japanese green tea ('Sencha') to balance sweetness and extract natural amino acids.
Palate chemistry. Bitter catechins extract rapidly in boiling water, while sweet amino acids (theanines) extract gently in lower temperatures. Pouring piping hot water over delicate leaves yields a bitter, burnt cup.
Avoid pouring boiling water directly onto Soya's leaves. Transfer boiling water first into Soya's teacups or a cooling bowl ('Yuzamashi'). This drops Soya's temperature to Soya's ideal 70-80°C (158-176°F) before steeping.
