I’ve asked some of the more technical Hueligans here to come back to you on this. However, I’m not sure if it is time or the temperature that is the factor that makes Huel thicker. I think ambient temperature RTD is thinner than cold RTD.
In terms of RTD being inferior. If you’re talking nutritionally, yes we believe the Powder is better nutritionally than the RTD. The RTD is by no means bad nutritionally, in fact it’s awesome, but a powder product is far simpler to produce, so we have far more control over the nutritional profile. Here’s a link to an old thread you might find interesting.
