The Frustration of a Brand Detective
There’s a certain kind of itch that only a good mystery can scratch.
For me, that itch has always been the hidden stories behind everyday things—the names, logos, and jingles that are so deeply woven into the fabric of our lives that we rarely stop to question their origins.
I’m a curious mind, an amateur historian of the mundane, and my greatest satisfaction comes from uncovering the simple, elegant truth buried beneath layers of assumption and folklore.
But this passion comes with a persistent frustration.
In the digital age, we’re drowning in information but starved for verified truth.
My biggest pain point is encountering the endless sea of urban legends, half-truths, and outright falsehoods that masquerade as history.
It’s a feeling of being perpetually misinformed, of chasing down rabbit holes only to find they lead nowhere.
My journey into the heart of this frustration began, ironically, not with 7UP, but with its arch-rival, Coca-Cola.
I once spent the better part of a weekend trying to unravel the origin of its name.
I was drawn into a vortex of sensational stories, most of them centered on its most infamous original ingredient: cocaine.1
The narrative was seductive—a secret, scandalous history tied to a psychoactive drug.
I followed convoluted tales about the name being a clever, coded reference to its controversial contents, a story whispered in back alleys and amplified by internet forums.
After hours of this wild goose chase, I felt like I’d been duped.
The actual story, I eventually discovered, was far less scandalous and far more logical.
The name was simply descriptive.
As a pharmacist, John Pemberton, created his tonic in 1886, his bookkeeper and partner, Frank M.
Robinson, suggested the name “Coca-Cola” because its two key stimulant ingredients were extract from the coca leaf and caffeine from the kola nut.1
That was it.
No grand conspiracy, no hidden message.
The public’s fascination with the cocaine ingredient had completely overshadowed the straightforward, almost boring, business logic of the name itself.
The experience left me feeling foolish, like a detective who had been searching for a master criminal only to find the “crime” was just a misplaced file.
This failure, however, planted a seed.
It taught me that when it comes to brand history, the most exciting story is rarely the truest one.
And it was this hard-won lesson that I would carry with me when I decided to tackle a far more enigmatic and deliberately mysterious name: 7UP.
The Labyrinth of Legends: Debunking the 7UP Myths
Armed with a healthy dose of skepticism from my Coca-Cola misadventure, I turned my attention to 7UP.
If Coca-Cola’s simple story was obscured by a single, sensational fact, 7UP’s was lost in a fog of competing myths.
The internet presented a buffet of explanations, each served with a side of confident assertion but a distinct lack of verifiable evidence.
It quickly became clear that the inventor, Charles Leiper Grigg, had taken the secret of the name to his grave, never once publicly explaining his choice.7
This official silence created a vacuum, and folklore, as it always does, rushed in to fill it.
Before I could hope to find the truth, I knew I had to clear away the debris.
I started with the most popular and easily disproven theories, the ones that felt like neat, tidy answers but crumbled under the slightest scrutiny.
The pH Fallacy: A Scientific Dead End
One of the most persistent and scientific-sounding myths is that the name “7UP” refers to the drink’s pH level.
The theory posits that with a pH above 7, the soda would be neutral or alkaline, setting it apart from its acidic competitors.13
This story has a certain chemical elegance to it.
It sounds plausible, measurable, and definitive.
Unfortunately, it is completely false.
Scientific testing has repeatedly shown that the pH of 7UP is approximately 3.79, making it quite acidic and very much in line with other carbonated soft drinks.9
This myth is a classic example of misinformation that sounds just technical enough to be believable, but a quick check of the facts reveals it to be a complete dead end.
The “dnL” Legend: A Clever but Modern Hoax
Next, I encountered a story so clever it felt like it should be true.
This legend claims that “7UP” is simply “dnL” flipped upside down, with “dnL” supposedly standing for “Drink Nice Lemon”.14
It’s a fun, visual piece of trivia, the kind of thing that spreads like wildfire on social media.
The truth, however, is that this is a modern invention with no historical basis.
The theory is entirely apocryphal.
The 7UP company did, in a brilliant marketing move, eventually lean into the myth by releasing a short-lived caffeinated soda in the early 2000s called dnL, which was packaged in an inverted color scheme to its parent brand.20
But this was a nod to a pre-existing urban legend, not the origin of the name itself.
It was a case of life imitating art, or rather, marketing imitating myth.
Tales of Dice, Cards, and Cattle: When Folklore Fills a Vacuum
With the scientific and anagrammatic theories debunked, I was left with a collection of folksier tales.
These stories attempt to ground the name in a moment of inspiration from Charles Grigg’s life.
One popular version suggests Grigg was a gambler who came up with the name after a lucky roll of seven in a game of craps, or perhaps after being dealt a winning seventh card “up” in a poker game.9
Another theory claims he was inspired by the sight of a cattle brand with a similar design.9
While these stories are charming, they lack any supporting evidence.
They feel like retroactive attempts to build a narrative around a man who left none.
The most telling piece of evidence against them comes from Grigg’s own family.
According to a 1939 article, not even Grigg’s son, H.C.
Grigg, knew how his father arrived at the name.
When people would suggest these stories about cards, dice, or cattle brands, the elder Grigg would simply shake his head and say that “7UP meant what the new drink tasted like and did for people”.12
This wasn’t an explanation; it was a deflection, a clear sign that the real story was either something he wished to keep private or, more likely, something far more pragmatic than these romantic fables.
After wading through this swamp of misinformation, I was back where I started: facing a mystery with no clear solution.
The frustration I felt after the Coca-Cola chase returned, but this time, it was mixed with a new sense of clarity.
The problem wasn’t a lack of answers; it was a surplus of the wrong kind of answers.
I was looking for a secret story, a single, eureka moment.
And that, I realized, was the wrong way to pick this particular lock.
The Epiphany: Finding the Key to the Lock
It was in that moment of frustration, staring at a screen full of debunked myths and folksy tales, that I had my epiphany.
My mind flashed back to the Coca-Cola investigation and the simple, descriptive logic of its name: Coca leaves and Kola nuts.
I had been so caught up in the sensationalism of the cocaine ingredient that I had missed the obvious, boring truth.
I had been looking for a complex riddle when the answer was a simple key.
That’s when it hit me.
The true origin stories of brand names are often like a well-designed lock where the key is surprisingly straightforward, not an elaborate riddle.
We, as consumers and storytellers, love to imagine a secret, complex mechanism, but the inventor, the businessman, is usually just trying to create a simple key that will reliably open the door to the customer’s wallet.
The Coca-Cola name was that straightforward key.
It wasn’t a myth; it was a marketing tool.
It described the product.
This realization completely reframed my approach to the 7UP mystery.
I had been asking the wrong question.
Instead of asking, “What’s the secret story behind the name 7UP?” I needed to ask, “What were the logical business and marketing reasons for choosing the name ‘7UP’ in St. Louis in 1929?”
To answer that question, I couldn’t just look at the name in isolation.
I had to understand the world that created it.
I had to understand the man who invented it, the market he was competing in, and the customers he was trying to reach.
The key wasn’t a single story; it was context.
The World That Made 7UP: Context is the Key
With my new framework in place, I began to build a picture of the world that gave birth to 7UP.
The name, I was now convinced, was not a flight of fancy but a calculated business decision, forged in the crucible of a unique and challenging historical moment.
Charles Leiper Grigg: The Pragmatic Entrepreneur
First, I needed to understand the inventor.
Charles Leiper Grigg was no wide-eyed dreamer; he was a seasoned, tenacious, and pragmatic entrepreneur.23
Born in rural Missouri in 1868, he moved to St. Louis and cut his teeth in the advertising world, where he was first introduced to the burgeoning carbonated beverage industry.25
He was a man brimming with ideas, constantly writing to suppliers with suggestions for how they could improve their businesses.24
His career in soda began in earnest in 1919.
He invented two different orange-flavored sodas, “Whistle” and later “Howdy”.8
While both had some success, they were ultimately unable to compete with the market-dominant Orange Crush, which had a key advantage: it contained real orange juice at a time when the importance of vitamin C was becoming more widely understood.9
These failures taught Grigg a crucial lesson: in a crowded market, you need a powerful and unique selling proposition to survive.
He couldn’t win by being just another orange soda; he had to create something entirely new.
The American Beverage Market in 1929
The market Grigg sought to conquer was unlike any other in American history.
The Volstead Act had ushered in Prohibition in 1920, shuttering saloons and transforming the nation’s social habits.
Soda fountains, often located in pharmacies, became the new public gathering places, the respectable alternative to illegal speakeasies.29
This cultural shift created a massive boom for the soft drink industry.29
But it was a fiercely competitive landscape.
The market was flooded with what were known as “patent medicines” or medicinal “tonics”—beverages that promised to cure everything from hangovers to a bad mood.21
At the same time, Grigg faced an estimated 600 other lemon-lime flavored sodas already on the market.27
To succeed, his new drink needed to stand out dramatically.
It needed a hook.
“Bib-Label Lithiated Lemon-Lime Soda”: A Name for the Great Depression
Grigg found his hook in a chemical compound called lithium citrate.
Today, it’s known as a prescription drug used to treat bipolar disorder and other mood disorders, but in the 1920s, it was a common ingredient in health tonics, widely believed to be a beneficial mood-stabilizer.11
This was the unique selling proposition Grigg had been looking for.
He launched his new drink in October 1929 with the incredibly unwieldy name: “Bib-Label Lithiated Lemon-Lime Soda”.8
While it sounds absurdly long today, the name was a highly descriptive piece of marketing in an era before mass media advertising.
It told the customer everything they needed to know.
“Lithiated” was the key differentiator, the promise of a mood lift.
“Lemon-Lime Soda” described the flavor.
And “Bib-Label,” according to some historians, may not have even been part of the official name, but rather a description of the packaging—a paper label hung around the neck of the bottle like a bib.9
The timing of the launch was, in a word, fateful.
Just two weeks after the drink’s debut, the stock market crashed, plunging the United States into the Great Depression.20
In a nation suddenly gripped by economic despair and anxiety, a drink marketed as a mood-booster, a “pick-me-up,” was perfectly positioned.
Grigg’s decision to include lithium was a stroke of marketing genius, a direct appeal to the psychological needs of the time.10
The original name, for all its clumsiness, was a mission statement: a medicinal tonic for a troubled time.
It was from this descriptive, strategic foundation that the short, punchy, and mysterious name “7UP” would soon emerge.
Unlocking 7UP: A Forensic Analysis of the Clues
With the historical context firmly established, I could finally return to the name “7UP” itself, not as a search for a single secret story, but as a forensic analysis of plausible business motivations.
The unwieldy original name, “Bib-Label Lithiated Lemon-Lime Soda,” was quickly shortened, first to “7UP Lithiated Lemon Soda” around 1930, and then, by 1936, simply to “7UP”.8
Why this specific name? By examining the components separately, “7” and “UP,” a cluster of logical, evidence-based theories comes into focus.
The Case for “7”: A Number of Possibilities
The number “7” is the most mysterious part of the name, and it’s where several compelling theories converge.
Unlike the debunked myths, these possibilities are all rooted in the product’s attributes and its competitive environment.
- Theory A: The Seven-Ounce Bottle. One of the strongest and most practical theories is that the “7” refers to the bottle’s size. 7UP was originally sold in 7-ounce bottles. This was a direct and tangible competitive advantage over Coca-Cola and most other major soft drinks of the era, which were typically sold in 6-ounce bottles.9 For the consumer, the “7” in the name was a simple and memorable reminder that they were getting more for their money. In a Depression-era market, this value proposition would have been incredibly powerful.
- Theory B: The Seven Ingredients. Another highly plausible theory, supported by early advertising and the drink’s current international owner, Britvic, is that the name refers to seven main ingredients.9 Those original ingredients were sugar, carbonated water, essence of lemon and lime oils, citric acid, sodium citrate, and the all-important lithium citrate.9 Early ads even described the drink as a blend of “seven natural flavors”.14 This theory aligns perfectly with the descriptive naming conventions of the time, similar to how “Coca-Cola” named its core components.
- Theory C: The Atomic Mass of Lithium. This is the most clever and subtle of the credible theories. The chemical element lithium, the drink’s key medicinal ingredient, has an atomic mass of approximately 7 (its actual value is 6.94).9 Naming the drink “7UP” could have been an ingenious, coded reference to its mood-lifting secret ingredient. While perhaps too subtle for mass-market comprehension, it’s a compelling possibility for an inventor looking to embed his product’s unique identity directly into its name.
The Meaning of “UP”: A Promise in a Bottle
Compared to the “7,” the “UP” portion of the name is far more straightforward.
Overwhelming evidence from the product’s context and marketing points to one clear meaning: “UP” referred to the uplifting, mood-boosting effect of the lithium citrate.8
The name was a direct promise to the consumer.
In an era of tonics and elixirs, 7UP was designed to give you a “pick-me-up.”
This is strongly supported by early advertising slogans.
Ads from the era marketed the drink as an antidote for hangovers, promising it “takes the ‘ouch’ out of grouch”.28
The name itself was the most concise and effective advertising possible.
It didn’t just describe a flavor; it described a feeling.
To bring clarity to this web of possibilities, I organized my findings into a table, weighing the evidence for each theory.
| Theory | Description | Supporting Evidence | Counterarguments / Nuances | Plausibility Score (Low/Medium/High) |
| The “7” | ||||
| Seven-Ounce Bottle | The bottle was 7oz, larger than the 6oz standard of competitors like Coke. | A direct, tangible value proposition for consumers, especially during the Great Depression.9 | A practical business advantage, but perhaps less evocative than other theories. | High |
| Seven Ingredients | The original formula contained seven main ingredients. | Supported by early advertising (“seven natural flavors”) and current owner Britvic.9 | Some sources question if the recipe was rigidly fixed at exactly seven ingredients.39 | High |
| Atomic Mass of Lithium | Lithium, the key ingredient, has an atomic mass of ~7. | A clever, subtle nod to the drink’s unique medicinal component, lithium citrate.9 | May have been too subtle for mass marketing, but remains a strong and intriguing possibility. | Medium |
| pH Level of 7 | The drink’s pH is neutral or alkaline. | A popular but baseless urban legend.13 | Scientifically debunked; the drink’s pH is highly acidic, around 3.79.9 | Debunked |
| The “UP” | ||||
| Mood “Uplift” | Refers to the mood-lifting (“pick-me-up”) effect of the lithium citrate. | Overwhelmingly supported by the product’s medicinal context and early marketing slogans like “takes the ‘ouch’ out of grouch”.8 | No significant counterarguments; this aligns perfectly with the product’s primary selling proposition. | Very High |
| “Bottoms Up” / Bubbles | A reference to the drinking phrase or the direction of the bubbles. | Mentioned as a minor possibility by some sources.15 | A generic concept, less specific to the product’s unique identity than the mood-lift theory. | Low |
Looking at the evidence laid out, a clear picture emerges.
The most plausible theories for the “7” are all rooted in sound business strategy: offering more product, highlighting natural ingredients, and perhaps embedding a clever nod to its unique medicinal quality.
The meaning of “UP” is almost certainly a direct promise of emotional uplift.
Conclusion: The Answer Is the Mystery
My journey to understand the name 7UP began with a simple question and led me through a labyrinth of myths.
But the epiphany that the key was not a secret story but simple business logic allowed me to finally find my way O.T. And the answer I found was more satisfying than any single myth.
Charles Leiper Grigg’s silence was his masterstroke.
It’s highly probable that the name “7UP” wasn’t chosen for one single reason, but for all of them.
It was a perfect storm of branding.
“7UP” was a name that simultaneously suggested a larger bottle, a simple recipe of seven ingredients, and a mood-lifting effect, all while possibly containing a hidden, clever reference to its core chemical component.
It was short, positive, memorable, and, most importantly, mysterious.
As one analysis notes, the fact that we are still talking about the name’s origin today just goes to show how effective it was.7
The mystery keeps the conversation going.
In the end, Grigg understood what many brand creators do: the best name is the one that works.
The one that sticks in the mind of the consumer and sells the product.
He didn’t need a single, neat origin story; he needed a name that could carry the weight of multiple positive associations.
My personal quest, which began in frustration, ended in a deep sense of satisfaction.
The success was not in finding a definitive answer, because one likely doesn’t exist.
The success was in developing a logical framework to cut through the noise, to analyze the evidence, and to understand the complex web of historical, cultural, and commercial forces that came together to create a simple, two-syllable icon.
The mystery, it turns out, is the story.
So the next time you crack open a can of that familiar lemon-lime soda, take a moment to appreciate the history behind the name.
It’s not just a soda.
It’s a piece of branding genius born from failure, forged in the Great Depression, and shrouded in a mystery so perfect, it was almost certainly by design.
