Brain chemistry and tea. What a combo! I'm suprised that this thread hasn't brought out our chemistry enthusiasts. I remember being quite struck by the mood altering effect of green tea when I first started to drink it. Now I notice it less. Probably because my baseline mind/body is now more in line with the state of mind that drinking tea helped to produce in the first place. It's official - I have tea brain.
Ugh, the woes of being a
tea head, eh murrius? lol

The reason gyokuro and matcha have the highest concentration of L-theanine is the shaded cultivation process. Sunlight helps to turn L-theanine into catechins.

L-theanine, one of amino acid, is high in the shade-grown teas such as Matcha & Gyokuro. L-theanine is "umami" or savory taste and this is why Matcha and Gyokuro have unique sweet taste.
