The good news is that you can save your leftover coffee and create special drinks and food items with it!

In this post I will go over storage tips if you have made too much coffee and want to save it.

Also go over how to re-heat your leftover coffee and ways you can still make use of it!

Your day-old coffee can be put to use in a hot beverage, cold beverage or even in baking. 

The shelf life of coffee depends on various storage methods, how it was brewed originally and how you want to use it.

So whether you prefer hot or iced coffee drinks, whole beans, or ground coffee, we will cover it all.

Keep reading as I go over tips and ideas on how you can get the most out of every fresh cup of coffee beyond the day you make it!

Let’s take a Closer Look at Brewing Methods

Different brewing methods may require specific approaches to storing and maintaining the freshness of your coffee. 

I will go over the different brewing methods you can use to prepare coffee and how it affects how your leftover coffee will taste.

The brewing process has a lot to do with the strength of the coffee and how it will be later after the first brew.

For example, espresso-based drinks are best enjoyed with freshly ground beans, while a regular coffee maker can be more forgiving.

While brewed coffee typically doesn’t have a strict “expiration date,” it’s essential to consider the freshness of your coffee when deciding how long it can last. 

Over time, coffee can become stale, and bitter resulting in a less flavorful coffee brew.

The shelf life of brewed coffee depends on where you store it.

Leaving your brewed coffee for an extended period of time at room temperature causes chemical reactions with the oxygen in the air causing it to deteriorate.

For the best flavor, brewed coffee can last for about 1-2 hours before you will notice that it starts losing its freshness. 

However, in the fridge, it can remain good for a long time, possibly up to 1-2 weeks.

Any airtight container is your best friend when it comes to preserving the freshness of your coffee. 

French Press

Coffee connoisseurs often prefer the French press method. 

This is my favorite way to make my daily coffee for the strength it gives to my brew, and since we live in the mountains, does not require electricity!

For the best taste, use freshly ground whole bean coffee that has been stored in an airtight container. 

Using fresh coffee beans, when making coffee from whole coffee beans, is the best way to get the freshest oils from the beans.

Always make sure that the beans are ground to a coarse consistency for the richest flavor.

If you use a package of coffee that is already ground, it will still be delicious!

Make sure you store coffee beans in an air-tight container. 

The same goes for when you store ground coffee too.

The bag of coffee needs to be rolled closed tightly and secured before putting into the storage container.

Fresh beans or fresh coffee grounds really do make the difference in freshness and how good your coffee will be the next day.

Cold Brew Coffee

Cold brew coffee is known for its mellow and less acidic flavor. 

To store cold brew concentrate, use an airtight container in the refrigerator. 

Dilute it with cold water when ready to enjoy.

Since cold brew coffee is already in a cool place to begin with, re-cooling to store it is not a problem.

The cold temperatures expected of a cold brew doesn’t require any special coffee equipment.

Either purchase at the grocery store or check out how you can make your own cold brew coffee!

Automatic Coffee Machine

If you are using an automatic coffee machine, you can still save your leftover coffee.

The strength that you made your coffee to begin with will determine the flavor carry over once reused.

I prefer to use the leftover coffee from the machine in methods other than making a hot beverage.

It works great as a liquid in a cake glaze, or making frozen cubes.

How long can coffee remain fresh? Does coffee go bad?

Black coffee can technically last in the fridge for a couple of weeks, but 1-2 weeks at the most where it will still be completely safe to drink.

It must be stored in an airtight container though.

For the best taste though, an expiration date of 2-3 days is optimal for the best taste of the coffee.

The first week is as far as I will go with storage time.

If it has a bitter taste, sour taste, or has any visible signs of mold, throw it out. 

Keep in mind that coffee with milk or creamer will last 2 days in the fridge as dairy products blended in decreases the time.

I usually add creamer or foam to my cup that I am going to drink and leave the rest in the coffee pot or French press.

Here are three storage tips to keep in mind:

– Use a glass jar or a sealed container specifically designed for coffee storage.

– Keep your coffee in a cool, dry place away from direct sunlight.

– Write the date you put it in the fridge and the date you should use it by on the container.

I store mine in an airtight glass mason jar

Mason jars are a popular option for leftover coffee storage. 

Their airtight seal helps keep coffee fresh, and the glass material prevents the absorption of odors from other foods in your fridge.

Its a good idea to store your mason jar of coffee in a cool, dark place to maintain its quality.

Although it is a great way to preserve a food product longer than other ways, eventually it does go bad, so use it up quickly.

Freezing Coffee into Cubes for Iced Coffee

If you’re a fan of iced coffee, freezing leftover coffee into ice cubes is a great way to extend your dollar!

It prevents brewed coffee from going to waste and it also prevents your iced coffee from becoming watered-down coffee as the ice melts. 

Simply pour your leftover coffee into an ice cube tray and freeze it.

Pop them out of the ice cube tray and store in a large freezer bag. 

The next time you make an iced coffee, use these coffee ice cubes for an extra kick of flavor.

If you are one of the long time coffee drinkers you may have heard of a frappuccino, a sort of coffee milkshake made at a coffee shop.

These coffee cubes are the perfect addition to a frappuccino that you whir up in the blender.

I love using them in my smoothies also so I get a great coffee kick!

How to reheat your leftover coffee to enjoy as you did originally

If you have leftover hot coffee, you can reheat it on the stovetop or in the microwave. 

The key is to do it gently to avoid making your coffee taste bitter. 

You can always add a splash of hot water to refresh the flavor if needed.

Keep watch over the coffee as you do not want to boil it. 

If you boil it accidently you can still drink it but the flavor of the coffee will be very bitter.

–Does the type of coffee used to make the brew determine how long it lasts once brewed?

Coffee made from whole coffee beans has a longer shelf life compared to coffee made from ground coffee.

Coffee beans have a protective outer layer, which helps preserve their freshness by shielding them from oxygen and moisture.

When you freshly grind coffee the protective layer has just been broken versus ground coffee, on the other hand that has a larger surface area exposed.

This makes it more susceptible to being a stale coffee before you even make your coffee. Instant coffee is even more susceptible. 

–Does it make a difference if the coffee is plain or flavored?

No, it doesn’t change the amount of time the coffee will stay fresh after brewed if it is flavored.

Usually the flavor comes from oils so it will last as long as the coffee bean oils will.

–Can I freeze my coffee into cubes if I have already added cream and sweetener?

Yes you can. If I have already added creamer and sweetener, this is my favorite way to store the leftover coffee.

Storing it in the fridge in a jar is only going to keep 2 days. This way if I have frozen it into cubes I am not out the coffee if I forget about it.

–Can I use my leftover coffee to water my plants?

You should only water plants with coffee once per week. Acid-loving plants, such as azaleas and blueberries, love coffee.

However, tomatoes and lavender may not fare well if you use coffee to fertilize them.

Be sure to check to see if your plant prefers acidic soil before using coffee or coffee grounds as fertilizer.

When using leftover liquid coffee for plants, it is a good idea to first dilute your coffee with more water, especially if you prefer your daily cup of java on the strong side.
