Being a natural green tea leaf with no chemical emulsifier, green tea powder does not dissolve in water. Rather, it suspends. Thus, a settlement occurs naturally after a while. And the settlement is proof that Matcha and Sencha powder are “real food”, as opposed to “artificially manufactured food.” When settlement happens, simply stir again or gently sway the cup to bring the suspension back. This way, you can enjoy the tea to the last drop. And, as the powder suspends in water rather than dissolves, the water temperature does not matter–the green tea powder mixes well even in cold water.
