If you like sour, and like the flavor of watermelon, this really brings out the best of both worlds. Both flavors are impactful, really better when its ICE cold. I sometimes freeze mine for a duration to make it slushy-like very refreshing, and the ice doesn't kill out the flavor.
Too many scoops obviously you're going to get a gritty after-taste. I tested with 1 scoop 1/2 it was a bit gritty, just do one full/overflowed scoop and you're good as gold, or just follow the instructions lol.
