How Long Does Brewed Coffee Last?

Brewed coffee can only be kept at room temperature for 30 minutes unless you want to lose its taste. It loses its optimal flavor and aroma owing to oxidation after a while.

Even though losing the freshness and natural taste is the worst thing that can happen, one thing is much worse: spoiled coffee. In this case, brewed coffee will become harmful, making it potentially hazardous to drink.

Let’s take a closer look at the reason!

The Chemistry Of Coffee Oxidation

Coffee beans oxidize when they come into contact with air. This occurs when you leave them open outside for a certain amount of time.

Roasted coffee beans are stored properly, which slows down the oxidation process and allows them to last for a few weeks.

Brewing coffee is also one kind of oxidation. When coffee beans come into contact with water, they release aromatics, oils, and acids. This chemical reaction contributes to a delicious cup of coffee, so it is essential to prevent it before brewing.

When creamer or milk is added to coffee, on the other hand, the coffee’s life is shortened to the length of the additional component, which promotes oxidation.

Flavor And Aroma

You should be aware that oxidation progress continues even after the coffee has been made into a drink. Although it isn’t apparent to the naked eye, such a reaction has a significant impact on the flavor of coffee beans.

It causes flavoring elements in coffee to deteriorate and be released into the air upon contact. When you put your coffee out for too long, the contact between hydrogen and oxygen changes the pH level of the coffee, causing it to taste bitter or stale.

7 Tips To Keeping Brewed Coffee Stay Fresh

The shelf life of brewed coffee is determined by what you do with it once made. Here are 7 easy tips to keep coffee fresh.

Remove The Coffee From The Heat Source

When making drip coffee, it is critical to take the coffee pot from the burner as soon as it is finished. It can oxidize more quickly and turn sour if you keep it on the burner.

Keep Coffee Hot Without Extra Heat

Transfer the coffee to airtight containers such as an air pot, carafe, or thermos after removing from the burner to eliminate excessive heat intake.

The airtight container can keep the heat and flavor of the coffee without allowing it to become bitter or off-tasting.

Put In The Fridge

Keeping the coffee cold extends the flavor and aroma of the coffee for over 2 hours outside. Brewed black coffee can usually be stored in the fridge for up to a week. You can reheat the cold-brewed coffee from the fridge, yet it won’t taste as wonderful as a newly made cup.

Make Coffee Ice Cubes

Rather than wasting leftover coffee, freeze it into ice cubes. It’s simple to make ice cubes: wait until the coffee is close to room temperature, fill the ice cube tray with coffee, and place it in the freezer.

You can store the ice cubes in the tray or transfer them to a ziplock bag to keep the flavor once it’s frozen. Iced coffee can be enjoyed whenever you want without having to pour your coffee in the usual manner.

Bartend Your Brewed Coffee

Coffee mixed cocktails are a fantastic way to take advantage of leftover coffee. They’re some of the most delectable mixed cocktails available right now.

Coffee cocktails range from simple to five-star versions. The way these cocktails blend bittersweet coffee and sweet liqueur will have you addicted.

Cooking With The Brewed Coffee
