Carnation is made by Nestle. I have boycotted Nestle for the last 30 years because they kill babies. Nestle bribes doctors in the developing world to give samples of baby formula to new mothers. These samples are precisely made to last just long enough for the mother’s breasts to dry up, at which point she must buy more formula or her baby dies. If she has no access to clean water, or if she cuts the recommend formulation to save money, the baby is also more likely to die.
The World Health Organization says this marketing tactic is responsible for the death of as many as 1.5 million babies every single year. And Nestle has been doing this for decades despite being repeatedly censured for it. If you want the full details, you can find all the documentation at Baby Milk Action.
But no, I’m sorry to tell you that you haven’t invented a new type of coffee. Super-cheap dollar store instant coffee, for example, usually referred to as a “coffee blend,” is usually made with a combination of instant coffee, chickory, and a grain like barley or wheat.
