Coffee has actually been called a lot of things in America including Joe, Java, mud, murk and Jamoke.
It’s hard to give a definite answer to this question “Why is coffee called a cup of Joe” but after thorough research, it is obvious there a few feasable and likely reasons.
- Josephus “Joe” Daniels, Secretary of the Navy during World War I banned alcohol aboard Navy ships, except on very special occasions. The crews average drink became a cup of coffee, or, as it was now referred to – A cup of Joe.
- Java and Jamoke in 1931 supplied some of the best coffee around. It is a popular opinion that the word Joe derived from the words Java and Jamoke being merged together.
Whatever the answer is to the question, it’s certainly an interesting insight in to how phrases and words become what they are.
