The average American consumes slightly more than three cups of coffee per day, according to the National Coffee Association, which is understandable given that coffee tastes good, provides a much-needed energy boost, and even has health benefits.
Many return to the coffee maker for a midday pick-me-up in the afternoon. Some coffee makers have a feature that keeps the coffee hot for a brief period of time, making it easy to refill your cup multiple times.
At some point, you may begin to wonder when your coffee will go bad. Brewing a new pot may help you avoid a bad taste, but if the coffee is black, there is likely little health risk. Here, we investigate how long you have before your brewed coffee becomes undrinkable.
Does Brew Coffee Expire?
After brewing a cup of coffee, you may wonder if time begins to pass. Leaving it on the hot plate of the coffee maker does buy you some time. There may be a function on your coffee maker that keeps the coffee hot for a predetermined amount of time.
Once that time has passed, the coffee will begin to cool and lose its freshness, altering its flavor. After approximately 30 minutes at room temperature, the flavor will be significantly diminished. However, if taste is not a concern, there is likely nothing to worry about.
If you are a coffee connoisseur who appreciates the flavor of your brew, you should consume it as quickly as possible before it reaches room temperature.
The flavor of stale coffee is drastically altered, and not in a positive way. However, it is still relatively safe to consume. Supriya Lal, RD, a registered dietitian, states, “You may consume coffee that is a day old if it is black and free of milk products.”
