For the matcha latte, put the green tea powder (matcha powder) in a bowl and mix it with the 80 ° C hot water using a matcha whisk, a small whisk or, even better, a small milk frother. So that the water is around 80 ° C, it should be left to stand in the kettle with the lid open for around 10 minutes after boiling.
Pour the tea into a glass or cup and pour frothed soy milk heated to no more than 80 ° C. Sweeten the drink with maple syrup if you like.
