Coffee is called a ‘cup of Joe’ because it is everyone’s everyday drink, just like Joe, a common name. Some people also associate it with Josephus Daniels, who issued the order to ban alcohol and encourage coffee on Navy ships. Soldiers in World War II also made the term popular. Coffee is also called “Java” because the Dutch grew coffee on Indonesia’s Java island and exported it worldwide.
Coffee has many names, but two of the most popular are “a cup of Joe” and “Java.” You may hear these terms often, but do you know where they came from?
These nicknames have interesting stories behind them. Some come from history, war, and culture, while others relate to places and people. From Navy ships to faraway islands, the journey of coffee is full of surprises.
In this blog, you will find out how coffee got these unique names and why they still matter today. Let’s find out!
Why is coffee called a cup of Joe?
One popular story comes from the U.S. Navy. In 1914, US Secretary of the Navy Josephus Daniels made a strict rule. He banned alcohol on all Navy ships [1]. He believed in a strict and moral lifestyle and wanted the Navy to be free of distractions like alcohol.
As a result, sailors turned to coffee as their only strong drink. Since Captain Josephus was behind this change, people began linking him to coffee, and calling their coffee “a cup of Josephus” or “a cup of Joe” in short as a way of mocking the change. Over time, this nickname became widely adopted.
It’s a fun tale, but historians say it probably isn’t true—the Navy had already been mostly dry long before that. Plus, the term “cup of joe” didn’t show up in writing until the 1930s.
Average Man Story
Another more plausible theory is linked to the idea that coffee is the everyday drink for the everyday person, and “Joe” is just a common, simple name. It made sense to link it to the everyday drink. It’s the kind of thing factory workers, truck drivers, and office folks all grab to start their day.
During World War II, American soldiers were nicknamed G.I. Joes, and every one of them had coffee in their C-rations. It was strong, hot, and easy to make—perfect for long days under tough conditions, and American soldiers (G.I. Joes) drank a lot of it [2]. Just like tea helped kick off the American Revolution, coffee became the drink that fueled soldiers through the war. Over time, calling it a “cup of Joe” just stuck, and now it’s a part of everyday language.
Martinson’s Joe Coffee
Another reason people say “cup of joe” might come from a man named Joe Martinson. He ran a coffee company in New York back in the late 1890s.
His mission was simple: bring a delicious, everyday coffee to working-class families who couldn’t afford fancy blends. As his brand grew, people would ask for a “cup of Martinson’s joe,” which eventually shortened to just a “cup of joe.”
Why is Coffee Called Java?
Indonesian Java
The name “Java” for coffee comes from the Indonesian island of Java. Back in the 17th century, Dutch colonists introduced coffee plants to this lush Indonesian island, transforming its landscape and global trade. The volcanic soil of Java proved perfect for growing coffee, creating beans with a rich, smooth flavor that quickly became legendary.
Traders and sailors began using “Java” as a synonym for coffee, spreading the term across oceans and continents. What started as a specific reference to coffee from the Indonesian island evolved into a universal slang term.
Mocha Java Story
Another related story is about a coffee blend called “Mocha Java.” This mix combines coffee beans from Mocha, Yemen, and Java, Indonesia.
Back in the early days of global trade, coffee traders discovered that blending the sweet, chocolaty Yemeni beans with the bold, earthy Indonesian coffee created an extraordinary flavor combination. This was the world’s first coffee blend, born from the meeting of two distinct coffee origins.
Over time, people started blending not just the coffee but the names too—“Mocha” and “Java” turned into slang like “jamoke” or “jamoka,” especially in the U.S. “Jamoke” later got shortened again to just “joe,” giving us the classic “cup of joe.”
Coffee was not always a Joe
Before it was called “Joe” or “Java,” coffee had many names. In Ethiopia, where coffee originally came from, it was known as “buna.” In Arabic countries, it was called “qahwa.” As coffee spread across the world, each country gave it a new name. But the drink remained the same, warm, energizing, and comforting.
The terms “Joe” and “Java” came much later, shaped by history, culture, and trade. These names reflect how coffee became a part of daily life, from Navy ships to local cafés. They show how a simple drink can carry stories from all over the world.
