Start by placing the matcha powder into a bowl or small jar and add hot water. Whisk vigorously with a bamboo whisk or small whisk until the mixture turns a smooth, deep green and becomes frothy, about 30 seconds. The sound of the whisk should be steady, and the mixture should be glossy and slightly thickened.
Fill a tall glass with large ice cubes, ensuring they crack and clink as they settle. This creates a satisfying sound and a cold base for your latte.
Pour the freshly whisked matcha over the ice, watching as the vibrant green begins to swirl and settle into the cold liquid, creating a beautiful contrast.
In a separate container, combine your milk with a splash of vanilla extract and sweetener if desired. Stir gently until the sweetener dissolves completely, and the mixture is uniform.
Pour the milk mixture slowly over the green matcha, causing a swirling vortex that blends the creamy milk with the earthy green liquid, creating a marbled effect.
Gently stir the latte with a spoon or straw to combine the layers slightly, watching the vibrant green settle into a velvety, frothy surface.
Enjoy immediately while the ice is cold and the drink is fresh, with the crackle of ice and the aroma of grassy matcha filling the senses.
