Did you know that the caffeine in coffee has a shelf life? You might not think this is possible, but it’s true.
The shelf life of coffee depends on how soon after roasting it’s consumed. Reduced-acidity coffees (such as many supermarket brands) have a shorter shelf life because they are unroasted and have an increased pH level. Because of this, they lose their flavor faster than other types of coffee beans.
This article explores the answer to “Does Expired Coffee Lose Its Caffeine?” Keep reading to learn more about how different storage conditions affect the taste and lifespan of your favorite caffeinated beverage.
Does Expired Coffee Lose Its Caffeine?
The answer is no, Based on this research, we know that caffeine is extremely stable. It’s also water-soluble, meaning that it doesn’t dissolve in fat or oil.
Caffeine is one of the most researched ingredients in food and beverages. Its effects have been studied on humans and animals, and it’s estimated that 94% of the world’s population consumes caffeine daily. Because of the popularity of this ingredient in many different types of beverages, as well as its effects and potential side effects, it has been extensively studied.
This means that when coffee beans are roasted, caffeine is unaffected. Coffee, however, is a different story. When seeds are roasted, caffeine is released from the seeds into the coffee beans. This means that the longer you let your coffee beans sit around unroasted, the greater the loss of caffeine.
Coffee that is ground and brewed, on the other hand, will have less caffeine than freshly roasted beans.
How Long Does Coffee Last?

Expiration of Coffee and Changes in Taste Over Time
When coffee beans are roasted, their natural oils, flavors, and aromas are released. Coffee is then ground and brewed to produce a beverage that many, including myself, can’t live without. The thing is, the longer coffee beans are left unroasted, the more of their natural oils they lose.
As these oils disappear, you start to experience a change in taste, with less flavor and aroma. If you buy whole beans and let them sit around unroasted for longer than a couple of months, you’ll notice this. The coffee will still contain the same amount of caffeine it always did, but it’s likely it will taste different.
This is because coffee beans naturally lose flavor over time.
How to Tell if Coffee Is Bad?
