Several people have mentioned that a plastic bottle would harm Huel’s image as an environmentally friendly company. Well, if and when Huel ever does go down the RTD road, why not sell it in a recyclable carton; like milk? The carton would have enough for, say, five servings; and the customer would keep it in his fridge.
You could also sell a special glass, with notches on the side showing the customer where to fill it up to to get a full serving.
I think it would have to be a fundamentally different drink, though. The soy-based drinks seem to have a better shelf life, as a general rule, than those based on oat or pea proteins like Huel. They’d probably have to invest loads of money in tweaking the formula, stabilizing it to survive in a carton for a week. I’m happy with the way the product works at the moment - it’s not that inconvenient to mix my own meals.
If they perhaps released an RTD meal as a totally separate product line, something like “X by Huel” (“x” being the new product name); and continued manufacturing and selling the powder as it is right now; that would tick everyone’s boxes. They could even base the RTD product on soy, since it seems to work better in that format, and so that Huel could also appeal to soy devotees. Anything’s possible in ten years time, when the company has expanded sufficiently!
