It was quite strong, it is a true instant. Only thing I can compare it to is Bula Kava House's green instant and that was a while ago but two heaping(ish) teaspoons a few times did the trick and I believe it is stronger than the Bula Kava house instant... Probably too expensive to do this every time so I will stick with medium grind. I'd say the effects are nice and balanced also. In a pinch or during travel I would definitely recommend.
