Rum and Coke

Rum and Coke is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Rum and Coke rather than just read about it. In short: Rum and Coke, or the Cuba libre ( KEW-bə LEE-bray, Spanish: [ˈkuβa ˈliβɾe]; literally "Free Cuba"), is a highball cocktail consisting of cola, rum, and in many recipes lime juice on ice. Traditionally, the cola ingredient is Coca-Cola ("Coke") and the alcohol is a light rum such as Bacardi; however, the drink may be made with various types of rums and cola brands, and lime juice may or may not be included.

Key takeaways

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

Reference excerpt

Rum and Coke, or the Cuba libre ( KEW-bə LEE-bray, Spanish: [ˈkuβa ˈliβɾe]; literally "Free Cuba"), is a highball cocktail consisting of cola, rum, and in many recipes lime juice on ice. Traditionally, the cola ingredient is Coca-Cola ("Coke") and the alcohol is a light rum such as Bacardi; however, the drink may be made with various types of rums and cola brands, and lime juice may or may not be included. The cocktail originated in the early 20th century in Cuba, after the country won independence in the Spanish–American War. It subsequently became popular across Cuba, the United States, and other countries. Its simple recipe and inexpensive, ubiquitous ingredients have made it one of the world's most popular alcoholic drinks. Drink critics often consider the drink mediocre, but it has been noted for its historical significance.

History The drink was created in Cuba in the early 1900s, but its exact origins are not certain. It became popular shortly after 1900, when bottled Coca-Cola was first imported into Cuba from the United States. Its origin is associated with the heavy U.S. presence in Cuba following the Spanish–American War of 1898; the drink's traditional name, "Cuba libre" (Free Cuba), was the slogan of the Cuban independence movement. The Cuba libre is sometimes said to have been created during the Spanish–American War. However, this predates the first distribution of Coca-Cola to Cuba in 1900. A drink called a "Cuba libre" was indeed known in 1898, but this was a mix of water and brown sugar. Fausto Rodriguez, a Bacardi advertising executive, claimed to have been present when the drink was first poured, and produced a notarized affidavit to that effect in 1965. According to Rodriguez, this took place in August 1900, when he was a 14-year-old messenger working for a member of the U.S. Army Signal Corps in Havana. One day at a local bar, Rodriguez's employer ordered Bacardi rum mixed with Coca-Cola. This intrigued a nearby group of American soldiers, who ordered a round for themselves, giving birth to a popular new drink. Bacardi published Rodriguez's affidavit in a Life magazine ad in 1966. However, Rodriguez's status as a Bacardi executive has led some commentators to doubt the veracity of his story. Another story states that the drink was first created in 1902 at Havana's El Floridita restaurant to celebrate the anniversary of Cuban independence. The drink became a staple in Cuba, catching on due to the pervasiveness of its ingredients. Havana was already known for its iced drinks in the 19th century, as it was one of the few warm-weather cities that had abundant stores of ice shipped down from colder regions. Bacardi and other Cuban rums also boomed after independence brought in large numbers of foreign tourists and investors, as well as new opportunities for exporting alcohol. Light rums such as Bacardi became favored for cocktails as they were considered to mix well. Coca-Cola had been a common mixer in the United States ever since it was first bottled in 1886, and it became a ubiquitous drink in many countries after it was first exported in 1900. Rum and Coke quickly spread from Cuba to the United States. In the early 20th century the cocktail, like Coca-Cola itself, was most popular in the Southern United States. During the Prohibition era from 1922 to 1933, Coca-Cola became a favored mixer for disguising the taste of low-quality rums, as well as other liquors. In 1921 H. L. Mencken jokingly wrote of a South Carolina variant called the "jump stiddy", which consisted of Coca-Cola mixed with denatured alcohol drained from automobile radiators. After Prohibition, rum and Coke became prevalent in the northern and western U.S. as well, and in both high-brow and low-brow circles. Rum and Coke achieved a new level of popularity during World War II. Starting in 1940, the United States established a series of outposts in the British West Indies to defend against the German Navy. The American presence created cross-cultural demand, with American servicemen and the locals developing tastes for each other's products. In particular, American military personnel took to Caribbean rum due to its inexpensiveness, while Coca-Cola became especially prevalent in the islands thanks to the company shipping it out with the military. Within the United States, imported rum became increasingly popular, as government quotas for industrial alcohol reduced the output of American distillers of domestic liquors. In 1943, Lord Invader's Calypso song "Rum and Coca-Cola" drew further attention to the drink in Trinidad. The song was an adaptation of Lionel Belasco's 1904 composition "L'Année Passée" with new lyrics about American soldiers in Trinidad cavorting with local girls and drinking rum and Coke. Comedian Morey Amsterdam plagiarized "Rum and Coca-Cola" and licensed it to the Andrews Sisters as his own work. The Andrews Sisters' version was a major hit in 1945 and further boosted the popularity of rum and Coke, especially in the military. Lord Invader and the owners of Belasco's composition successfully sued Amsterdam for the song's rights. During the Cuban Revolution in 1959, Bacardi fled to Puerto Rico. The following year, the U.S. placed an embargo against Cuba, which made Cuban-made rum unavailable in the U.S. and Coca-Cola largely unavailable in Cuba. As such, it became difficult to make a rum and Coke with its traditional ingredients in either country.

Worked examples

Example 1 — a first encounter with Rum and Coke

Start with the simplest possible case. Write down what Rum and Coke claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Rum and Coke 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 Rum and Coke 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 Rum and Coke

In research
Rum and Coke appears in science 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 Rum and Coke 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
Rum and Coke is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacardi, Caffeinated alcoholic drinks, Caribbean drinks, so understanding it makes those chapters shorter.
In everyday life
Look for Rum and Coke 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.
