Cacao is superior
This stuff comes with release notes! I've tried the neutral flavor (v1.8) and cacao (v1.9) which were both the latest formula at the time of purchase (purchased directly from Soylent). The cacao is far superior to the neutral IMO. The cacao flavor is quite prominent and it takes similar to slimfast or boost. We make our soylent at night in the air tight pitcher that came for free with our first purchase, and that bit of soaking in the water over night in the fridge keeps it from getting lumpy or gritty; it also helps to add ice as an agitator, as wet solyent can get sticky. We have two people drinking it, so consuming the 5 meals from the pitcher in 2 days (before it goes bad) isn't really an issue. If you were going to make single servings, pick up a blender bottle with the ball whisk, and that comes out smooth almost every time.
