As a long time Soylent fan, I’m going to be honest here: The new bottle is terrible, and the new flavor vanilla has a sickening chemical undertone. Perhaps the taste was altered as a result of the fact that adhesive is now being used, since there is a foil seal on the inside of the bottle cap. I say this as a possibility only because of reports I’ve read that people drinking Cacao in the new bottles have noticed this same problem as well, which saddens me because I drink Cacao exclusively. So far I am still receiving squircle bottles from Amazon, but I fear that the next shipment may finally be the new bottle design. The larger problem is, in my opinion, the possibility that this adhesive may be altering the taste of other flavors as well.
Quite frankly I would take the harder to open squircle bottles, which only required one step and had no chemical taste lingering, instead of this new larger bottle with 3 steps to open, a bottle opening that feels weird to drink out of, and an adhesive that seems to be altering the taste. I will withhold my own personal judgment on Cacao until I get Cacao in the new bottles, but I promise you I will move on from Soylent if it ends up having a subtly toxic taste to it. Like come on people, you want to make money yeah? Listen to your damn customers.
