One recipe in the book titled "Dr Peppers Pepsin Bitters" was of particular interest, and some speculated it could be an early recipe for Dr Pepper. However, Keurig Dr Pepper insists it is not the formula for Dr Pepper, but is instead a medicinal recipe for a digestive aid. The book was put up for auction in May 2009, but no one purchased it.
