Key takeaways

  • Pepsi belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Pepsi to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Pepsi from memory before moving on to harder problems.

Reference excerpt

Pepsi is a carbonated soft drink with a cola flavor, the flagship product of PepsiCo. In 2023, Pepsi was the second most valuable soft drink brand worldwide behind Coca-Cola; the two share a long-standing rivalry in what has been called the "cola wars". Pepsi, originally created in 1893 by Caleb Bradham and named "Brad's Drink," was first sold in his drugstore in New Bern, North Carolina. Renamed "Pepsi-Cola" in 1898 due to its supposed digestive benefits, its name was shortened in marketing to "Pepsi" as early as 1951. Early on, Pepsi struggled with financial stability, going bankrupt in 1923 but was subsequently purchased and revived by Charles Guth, who reformulated the syrup. Pepsi gained popularity with the introduction of a 12-ounce bottle during the Great Depression and clever marketing strategies like the "Nickel, Nickel" jingle, doubling sales by emphasizing its value. The mid-20th century saw Pepsi targeting the African American market, a then-untapped demographic, with positive portrayals and endorsements from prominent figures, boosting its market share. Pepsi's rivalry with Coca-Cola, highlighted by the "cola wars", led to significant cultural and market competition, including the "Pepsi Challenge" taste tests and the introduction of New Coke in response. Pepsi's expansion into international markets has seen varied success, with notable ventures into the Soviet Union via a landmark barter deal and enduring popularity in certain regions over Coca-Cola. Despite occasional controversies, such as an aborted Madonna advertisement and the "Pepsi Number Fever" fiasco in the Philippines, Pepsi has remained a prominent global brand, partly thanks to innovative marketing campaigns and sponsorships in sports and entertainment. PepsiCo have also launched other drinks under the Pepsi brand, such as Diet Pepsi and Pepsi Max, that make up the brand portfolio today on top of the original Pepsi cola.

History

Pepsi was first invented in 1893 as "Brad's Drink" by Caleb Bradham, who sold the drink at his drugstore in New Bern, North Carolina. Bradham sought to create a fountain drink that was appealing and would aid in digestion and boost energy. It was renamed "Pepsi-Cola" in 1898 due to its formula's inclusion of essence of pepsin. This was a then-common medicinal preparation made from the digestive enzyme pepsin, with glycerin and a mild alcohol added. It was often used as an additive to make bitter medicines palatable, as well as for curdling milk. Although this point is seemingly disputed by modern writers, the earliest print advertisements for the beverage carried the subtitle "The Pepsin Drink", and boasted its presence for the sake of relieving indigestion (dyspepsia), as well as alleviating headaches and drowsiness. A key selling point in a 1902 advertisement claimed that a glass of Pepsi-Cola contained a teaspoon's worth of the concoction. The original recipe also included sugar and vanilla.

Bradham would incorporate the Pepsi-Cola Company on December 24, 1902, and moved the bottling of Pepsi from his drugstore to a rented warehouse in 1903. That year, Bradham would sell 7,968 gallons of syrup. The next year, Pepsi would be introduced in six-ounce bottles, and sales increased to 19,848 gallons. In 1909, automobile race pioneer Barney Oldfield was the first celebrity to endorse Pepsi, describing it as "A bully drink...refreshing, invigorating, a fine bracer before a race." The advertising theme "Delicious and Healthful" was then used over the next two decades. In 1923, the Pepsi-Cola Company entered bankruptcy—in large part due to financial losses incurred by speculating on the wildly fluctuating sugar prices as a result of World War I. Assets were sold and Roy C. Megargel bought the Pepsi trademark. Megargel was unsuccessful in efforts to find funding to revive the brand and soon Pepsi-Cola's assets were purchased by Charles Guth, the president of Loft, Inc. Loft was a candy manufacturer with retail stores that contained soda fountains. He sought to replace Coca-Cola at his stores' fountains after The Coca-Cola Company refused to give him additional discounts on syrup. Guth then had Loft's chemists reformulate the Pepsi-Cola syrup formula. On three occasions between 1922 and 1933, the Coca-Cola Company was offered the opportunity to purchase the Pepsi-Cola Company, which it declined on each occasion.

Growth in popularity

During the Great Depression, Pepsi gained popularity following the introduction in 1934 of a 12-ounce (355 mL) bottle. Prior to that, Pepsi and Coca-Cola sold their drinks in 6.5-ounce (192 mL) servings for about $0.05 a bottle. With a radio advertising campaign featuring the popular jingle "Nickel, Nickel" – first recorded by the Tune Twisters in 1940 – Pepsi encouraged price-conscious consumers to double the volume their nickels could purchase. The jingle is arranged in a way that loops, creating a never-ending tune:"Pepsi-Cola hits the spot / Twelve full ounces, that's a lot / Twice as much for a nickel, too / Pepsi-Cola is the drink for you."Coming at a time of economic crisis, the campaign succeeded in boosting Pepsi's status. From 1936 to 1938, Pepsi-Cola's profits doubled. Pepsi's success under Charles Guth came while the Loft Candy business was faltering. Since he had initially used Loft's finances and facilities to establish the new Pepsi success, the near-bankrupt Loft Company sued Guth for possession of the Pepsi-Cola company. A long legal battle, Guth v. Loft Inc., then ensued, with the case reaching the Delaware Supreme Court and ultimately ending in a loss for Guth. The Pepsi-Cola name would be shortened to simply "Pepsi" as early as 1945, when their bottles transitioned from standard paper labels to the applied color label (ACL) process, which involved screen-printing enamel paint graphics directly onto the bottle at a high temperature. The neck of the new bottle design displayed a small ovoid Pepsi-Cola logo in color on the front, and a truncated version of the script reading "Pepsi" on the opposite side. This motif would be carried over when a new bottle design and logo were introduced in mid-1951. When the drink was rebranded in 1962, two versions of the same logo with either name were used interchangeably. By 1969, the drink would almost exclusively be referred to as "Pepsi", with the full name retained for secondary uses.

Worked examples

Example 1 — a first encounter with Pepsi

Start with the simplest possible case. Write down what Pepsi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pepsi before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pepsi ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pepsi

In research
Pepsi appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pepsi in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pepsi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1893 establishments in North Carolina, American drinks, Britvic, so understanding it makes those chapters shorter.
In everyday life
Look for Pepsi outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
