C. W. Post established his company in Battle Creek, Michigan, having lived there since 1891, when he was a patient at a holistic sanitarium operated by Dr. John Harvey Kellogg. Dr. Kellogg, with his brother W. K. Kellogg, had developed a dry corn flake cereal that was part of their patients’ diet. Post's first product, introduced in 1895, was not a cereal, however, but a roasted, cereal-based beverage, Postum. Having developed an aversion to coffee during his time in the sanitarium, Post positioned Postum as a healthy alternative. Its advertising slogan, which he coined himself, was, "There's a Reason." Postum's main ingredients were naturally caffeine-free wheat grain, bran, and molasses. Initially, Postum had to be brewed like coffee, but in 1911, Post introduced a powdered, instant formulation. This version of the product was manufactured in Battle Creek until it was discontinued in 2007. As of January 2013, Eliza's Quest Food had succeeded in returning Postum to many grocery stores across the United States and Canada.
