why is coffee called joe
Coffee is called “joe” in American English, but there isn’t one proven origin story—there are several plausible theories that all circle around coffee being the everyday person’s drink.
Quick Scoop
The leading theories
- “Jamoke” → “Joe” (linguistic shortcut)
- In the early 1900s, coffee was sometimes called “jamoke,” a blend of “java” and “mocha,” two popular coffee terms.
* Over time, “jamoke” may have been shortened in casual speech to “joe,” just like many slang words get clipped.
- Joe Martinson’s coffee brand
- New York coffee roaster Joe Martinson founded Martinson Coffee in 1898, and locals allegedly called it “Joe’s coffee” or a “cup of Joe.”
* The company later trademarked “cup of joe,” which supports the idea that the phrase spread from this branding into wider American slang by the 1930s.
- Every “average Joe’s” drink
- Another popular explanation is that “joe” refers to the “average Joe”—the ordinary person—and coffee was the common, everyday drink of workers and soldiers.
* This fits how the phrase is used today: a plain, regular cup of coffee, not something fancy or specialty.
- Navy and military legends (likely myths)
- One story links it to U.S. Navy Secretary Josephus Daniels allegedly banning alcohol on ships, supposedly making coffee the strongest drink available and earning it the name “a cup of Joe.”
* Historians point out that the phrase “cup of joe” doesn’t clearly appear in writing until around the 1930s, years after Daniels’s 1914 order, so this is considered more legend than solid fact.
- “Cup of George” → “Geo” → “Joe” (soldier slang)
- During earlier 20th‑century wars, some soldiers drank instant coffee supplied by George Washington (a coffee entrepreneur, not the president) and allegedly called it a “cup of George.”
* One theory says “George” became “Geo,” then morphed into “joe,” though this is less widely accepted than the jamoke or Martinson explanations.
What most people think today
- Modern coffee historians generally treat “jamoke → joe” and Joe Martinson’s brand as the most linguistically and historically plausible sources, while the Navy and “cup of George” stories are seen as colorful folklore.
- Regardless of which origin you prefer, “cup of joe” has stuck because it perfectly matches the idea of coffee as a simple, no‑nonsense drink for the everyday Joe.
