Sift 1 teaspoon of matcha powder into your bowl. This breaks up clumps and ensures smooth foam.
Slowly add 1 oz (30ml) of hot water around 175°F/80°C. Do not use boiling water.
Whisk vigorously using a bamboo whisk in fast W or M motions. Move quickly until you see microfoam (tiny, uniform bubbles, not big soapy ones) forming on the surface. This takes about 30 seconds.
Add the remaining 1 oz (30ml) of hot water.
Whisk again using the same W motion for another 30-60 seconds
You should now have a clear layer of fine microfoam on top.
Fill a glass halfway or three-quarters full with ice. Add 5 oz (about 150ml) of cold water.
Pour your whisked matcha from the bowl over the ice.
Enjoy immediately while fresh!
Notes
Disclaimer. This matcha americano is best for experienced matcha lovers. It's pure and unsweetened, without any extras to mask the flavor.Since matcha is the only ingredient (besides water), its quality is everything. It should be extremely green (not dull or yellowy). The texture should not be coarse.
