What You'll Learn

Dr Pepper's formula is a closely guarded secret
The formula for Dr Pepper is a closely guarded secret, with only three people privy to the information at any one time. The company has never divulged any of the ingredients that make up its proprietary recipe, apart from confirming that prune juice is not included.
The soft drink's unique blend of 23 flavours was created by pharmacist Charles Alderton in 1885 at Morrison's Old Corner Drug Store in Waco, Texas. Alderton set out to make a soda syrup that tasted the way the store smelled. He kept notes on his concoctions in a journal, and after many experiments, he landed on the flavour known today.
The company may have inadvertently fuelled the spread of the prune juice rumour by keeping its product's formula secret. The Dr Pepper recipe is allegedly divided into two parts, each locked in a separate Dallas bank, ensuring no single person can possess the complete formula.
In 2009, an old ledger from Morrison's Old Corner Drug was discovered in a Texas antique store. The ledger contained a formula for "D Peppers Pepsin Bitter", with ingredients including mandrake root and syrup. However, Dr Pepper Snapple Group stated the recipe did not resemble any Dr Pepper formula, and mixing the listed ingredients would not produce anything close to the soft drink's flavour.
While methods exist to determine a product's reactants, the exact recipe for Dr Pepper remains a mystery. The secrecy surrounding the formula may be a marketing strategy, as competitors will create their own versions, and consumers are intrigued by the mystery.

The drink's recipe is kept in two separate Dallas bank vaults
The recipe for Dr Pepper is a closely guarded secret. It is so closely guarded, in fact, that it is divided into two parts, each kept in a separate bank vault in Dallas. This means that no single person can ever be in possession of the whole formula. Only four people are said to know the full recipe.
The drink has been the subject of many rumours, including that it contains prune juice. This is not true, and the company has addressed this rumour in a brochure, stating:
> There are 23 flavours and other ingredients (none of which are prunes) that produce the inimitable taste of Dr Pepper.
The FAQ section of the Dr Pepper website also notes that:
> Dr Pepper is a unique blend of natural and artificial flavours; it does not contain prune juice.
The company's secrecy around the recipe may have inadvertently fuelled the spread of this rumour, which has persisted since about 1930.

The drink was created in 1885 by Waco pharmacist Charles Alderton
Dr Pepper is a carbonated soft drink that was created in the 1880s by the American pharmacist Charles Alderton in Waco, Texas. Alderton was born in Brooklyn, New York, in 1857, the eldest of five children to English parents. He studied medicine at the University of Texas Medical Branch in Galveston and worked as a pharmacist in Waco at Morrison's Old Corner Drug Store, which had a soda fountain. Alderton created Dr Pepper after noticing that customers were tiring of traditional soda flavours like sarsaparilla, lemon, and vanilla. He began experimenting with new flavour combinations and eventually settled on a 23-ingredient mix combined with phosphoric acid to give it tang.
The drink was first sold on December 1, 1885, and was ordered by asking the soda attendant to "shoot a Waco". The formula was then given to the owner of the store, Wade Morrison, who named it Dr. Pepper. The name was chosen in honour of Dr. Charles T. Pepper, a Virginia doctor who had given Morrison his first job. Another story suggests that Morrison named the drink after Dr. Pepper because he had once been in love with the doctor's daughter.
The drink was introduced nationally at the 1904 Louisiana Purchase Exposition, also known as the World's Fair Exposition in St. Louis, Missouri, where it was introduced to almost 20 million people. It was the first soft drink of its kind and preceded the introduction of Coca-Cola by one year. The Artesian Manufacturing and Bottling Company, located in downtown Waco, Texas, was the first building specifically built to bottle Dr Pepper, and it operated from 1906 until the 1960s. Today, the building houses the Dr Pepper Museum, which has three floors of exhibits, a working old-fashioned soda fountain, and a gift store of Dr Pepper memorabilia.
Despite the long-lived rumour that Dr Pepper contains prune juice, the company has confirmed that it does not. The belief that it contains prune juice has been around since about 1930, and the company may have inadvertently encouraged the spread of the rumour by keeping the product's formula a secret. The formula is allegedly divided into two parts, each locked in a separate Dallas bank, so no one person can possess the whole formula.

The drink is said to contain 23 flavours
The belief that Dr Pepper contains prune juice has been around since the 1930s. However, the manufacturer has consistently denied this claim. The company's FAQ page states that Dr Pepper is a blend of natural and artificial flavours and does not contain prune juice. Additionally, a brochure released by the company mentions that the drink contains 23 flavours, none of which are prunes.
The origin of the rumour can be traced back to the secrecy surrounding the Dr Pepper recipe. The formula is allegedly divided into two parts, each kept in a separate Dallas bank, ensuring that no single person possesses the complete formula. This air of mystery may have fuelled speculation about the drink's ingredients, including the persistent prune juice theory.
While the exact 23 flavours remain a closely guarded secret, some commonly suspected ingredients include citrus, cinnamon, vanilla, and denatured rum. These flavours are also found in supermarket-brand knockoffs of Dr Pepper, indicating that they may play a significant role in the distinctive taste profile.
The unique blend of these 23 flavours has contributed to the enduring popularity of Dr Pepper, making it the oldest soft drink still available on supermarket shelves nationwide. The formula was created in 1885 by Waco pharmacist Charles Alderton, who worked for Morrison's Old Corner Drug Store in Texas. The drink's name, "Dr. Pepper," is rumoured to have originated from a sarcastic suggestion by Wade Morrison, the owner of the store and a former colleague of Dr. Charles Pepper.
In conclusion, despite the longstanding rumour, Dr Pepper does not contain prune juice. The drink's unique flavour comes from a combination of 23 different flavours, carefully blended to create a distinctive and much-loved beverage.

The period after Dr was dropped from the logo in 1950
Dr Pepper is a unique soft drink with a long history and a dedicated fan base. The period after "Dr" was dropped from the logo in 1950, marking a significant change in the brand's visual identity. This period was removed due to a font change that made the lowercase "r" consist of a small slanted line with a dot at its upper right. The placement of the period after this new "r" made the two appear as a colon, altering the "r" into an "i". Thus, "Dr. Pepper" looked like "Di: Pepper", and the solution was to remove the period. This change is an example of how the Dr Pepper logo has evolved over time to stay relevant and reflect global design trends.
The 1950s logo featured a bold, dark red contour that traced the wordmark, creating a standout feature against a pristine white background. The font used was a crisp san-serif, reflecting the progressive spirit of the era and embracing a modern flair. This shift in design showcased the brand's commitment to innovation and adaptability, ensuring the logo remained a beloved and recognisable icon.
During this period, Dr Pepper's slogan was "the friendly Pepper-Upper," which helped establish its association with rock and roll music in the 1960s, including its presence on Dick Clark's American Bandstand TV show. The company also continued to innovate with its products, introducing Diet Dr Pepper and additional flavours in the 2000s.
It is important to note that despite persistent rumours, Dr Pepper does not contain prune juice. The company has explicitly stated that it is "a unique blend of natural and artificial flavours" and does not include prunes or plum. This rumour has been around since the 1930s, and the company has tried to address it directly, but the secrecy of the product's formula may have inadvertently fuelled the speculation.
The evolution of the Dr Pepper logo, including the decision to drop the period after "Dr" in 1950, showcases the brand's ability to adapt and stay relevant while maintaining its rich history and unique flavour profile.
