In fact, according to a study done at the college I attended, a comparison per-volume of prepared matcha and prepared coffee (like, 1 liquid ounce of matcha to one liquid ounce of coffee) showed matcha has more caffeine than coffee does.
So if you're relatively sensitive to caffeine, that might be your culprit.
Kestrel, riddle me this...
I was curious, in that study, did they compare matcha to other teas and if they did, was it based on equal volumes of prepared tea or the equal weights of dry tea leaves to matcha powder. The reason I ask is because I was under the impression that almost 90% of caffeine leaches out of tea leaves in the first minute of brewing because caffeine is very water soluble. Therefore, a matcha preparation should only have around 10% more caffeine if you prepared teas with equal weights of tea leaves and matcha powder.
If however they did the study based on equal weights of leaves to powder, and the caffeine was still much higher (significantly in excess of a 10% differential) in the matcha preparation, then we are not receiving accurate info on the solubility of caffeine from the tea industry.
