I was really curious. My only "GABA experience" so far was limited to the green teas from Japan, and they taste like broth. I mean it! Interesting but not exactly my kind of tea. This one offers a completely different experience. It has the delicate touch of the oolongs from Taïwan. Now, regarding the "relaxing" part... for some reasons I get rather refreshed and energized by GABA teas, and this one makes no exception :-)
