That is the point… U&U needs much less water than Vanilla!!! There is too much water in your U&U!
U&U and Vanilla are not the same products, why would they need the same amount of water? That is the first thing I have noticed, when I have drunk my first U&U meal!
See my review of U&U here: Google Workspace Updates: New community features for Google Chat and an update on Currents
Here are the amounts I’ve found to be correct, for the same thickness:
For 690-700 Kcal:
Huel U&U: 165 g (+650 ml)
Huel Vanilla: 160 g (+900 ml)
Yes, for the same thickness, 650 ml water on one hand, 900 ml on the other hand! And no separation in both cases…
So, don’t be surprised, if you use so much water in U&U, to have such a separation in the shake!
