Why brewed coffee goes bad?

Coffee is composed of several compounds: that include carbohydrates, lipids, and amino acids.

Does brewed coffee go bad in the refrigerator?

If you kept the brewed coffee in the refrigerator, it can still lose its taste and aroma due to a chemical process, oxidation.

When refrigerated, the oxidation process slows down due to decreased temperature. To make this process more slowly, try to keep your brewed coffee in an air-tight glass container.

What happens when you refrigerate brewed coffee?

Refrigerating the coffee to increase its life span or to use it conveniently when required is a good idea. But this aspect has a bad picture too.

Coffee can quickly pick up the aroma from other things that are refrigerated along with it. This makes the coffee taste weird. To overcome this issue, you can use air-tight containers (mason jars with a rubber seal) or a thermos bottle. But still, certain things give off a nasty smell, that can easily creep into the coffee even if it is kept in an air-tight container.

The flavor degrades

Storing the brewed coffee in the refrigerator can cause its flavor to degrade. When used, it will be having a less pronounced coffee flavor and maybe a bit bland. Again, you have to keep it in an airtight container so that the flavor can be degraded only to a minimum.
