Why Is Coffee Called a “Cup of Joe”?

Fancy a "cup of Joe"?

Where does the term cup of joe come from??

Of all the nicknames to grace the drink world, “Joe” has to be the strangest.

If you happen to have an overactive imagination like me, you may wonder: why is coffee called Joe? (now i'm also wondering 'why is coffee called java'?)

As you may have already expected, there is no single answer to that question. As I break down the multiple explanations, I’ll let you decide which makes the most sense (or sounds the coolest).

just a cup of joe please - An Association of Averages

If you see coffee as the everyman’s drink, then the secret to its nickname isn’t that hard to guess. “The average Joe” is a common American reference to the everyday man, and coffee is one of the most common beverages, regardless of social class.

The association is simple: an average drink for the average man. Some nameless buster walks into your diner (yes, we’ve reverted back to the 1960s) and what does he order? He orders the same drink every other nameless buster at the bar is drinking: A cup of joe.

Simple Linguistics

Younger generations today may be familiar with nicknames like mocha or java for coffee, even if they don’t regularly use them. These terms have been around for most of the 20th century, and back in the 1930s people would combine these into “jamoke.”

Whether its because they couldn’t get over their obvious obsession with renaming everything, or because they realized that “jamoke” was just ridiculous, some people may have shortened it to simply “Joe.”

Linguists who are fond of this argument point out that many slang terms constantly go through a process of shortening. Just look at the de-evolution of “what is up” and you get the picture.

Mocking the Boss

The real reason coffee is called your average make American name may just be a prolonged joke originating from disgruntled WWI sailors. The story goes that a strict secretary of the American Navy, a man named Joseph Daniels, sought to limit all the debauchery going on in the Navy.

Though it was already difficult to get your hands on alcohol while on a Navy ship or base, Mr. Joseph Daniels was committed to making it even harder. With a sudden lack of the good stuff, sailors quickly began drinking more and more coffee.

Since openly insulting your superior (in this case very superior) officer is a bit of a no-no in the Navy, sailors began calling their coffee “a cup of Joseph Daniels” in mock salute, which was shortened to “a cup of Joe.”

It's Probably Just Marketing

Let’s face it: pop culture dominates many aspects of our daily lives, and marketers dominate pop culture. So when you ask how a cup of joe got its nickname, I might as well respond with, “How does anything in the US get its name? Marketing.”

The term “cup of Joe” was actually trademarked by Martinson Coffee, an American coffee company that’s been around since 1898. In its early days, people may have called Martinson’s coffee “Joe’s coffee” in reference to the owner, Joe Martinson.

Over time, this nickname may have switched and expanded across the US as the company grew over the years.
