Why WWII Navy Veterans Added Salt to Their Coffee

Those black beans became just as important for fueling the Navy as diesel fuel or uranium. Descendants of sailors who fought in World War II might have noticed their dad or grandpa adding a dash of salt to their morning coffee and wondered why on Earth they would do that.

There are actually two reasons “old salts” have been known to do this (and it’s not why they’re called old salts).

Aboard Navy ships mornings don’t happen at the same time for every sailor. As a result, the ship keeps coffee brewing all the time, so no matter when your morning is, a cup of joe is ready somewhere.

But anyone who has ever had a big steaming cup of government coffee knows, it’s not the best. That’s true today, and it was true during World War II.

When your coffee tastes terrible you have a few options. You can add cream and sugar — if it’s available. Or you can cut the bitter taste some other way. For World War II era sailors, the most readily available way was through the use of table salt.

You might have seen some people salting fruit like cantaloupe and grapefruit or adding salt to their beer. That’s because when presented with both flavors at the same time, human taste buds can be fooled into ignoring bitter tastes and reacting more strongly to salty tastes instead. Salting coffee did the trick to reduce the bitter flavor and made the brew more palatable.

But that’s not the only reason sailors of that era grew accustomed to salty coffee, bringing the preference home with them when the war ended. The desalination units on World War II-era ships that converted sea water to drinking water weren’t 100% efficient at removing the salt from the water. As a result, the coffee retained a slightly salty flavor, so sailors just got used to the taste.

Now that we know that trick, we can all feel free to buy the world’s worst bulk coffee and, with a little salt, make it seem like Juan Valdez himself brought it to you from the mountains of Colombia.
