I am not sure if there is any plan to ship flavoured Soylent in the future but in my opinion, that would be great as I heard that the classic soylent becomes “boring” after some time. Fruit and other flavour such as chocolate, coffee or vanilla flavor. I know we can DIY, but that just defeats one of the purpose of it, preparing food easily. And as for production, when will Soylent enter mass production(more than what it is at this moment)
depends how easily bored you are.
