I just started drinking matcha several weeks ago. This is such an incredible experience. I have found that all vendors tell you to use too much powder. I use around half, 2 grams per 120 ml. But be prepared to experiment.
I cannot stress enough the need to sift the powder before each use. I use a metal infuser from a tetsubin, works great. The vibrantly colored green matcha powder comes out all nice and fluffed up.
Oh, and the elixer is this incredible liquid emerald color. WOW.
OK, the question begs to be asked. Since you are a flavored tea drinker, will you drink your matcha straight?????
Oh, there are some good internet videos on making matcha, let me know if you are interested.
