How To Store Used Coffee Grounds

You make your coffee, but you want to keep the grounds you used.

Perhaps you have another hobby where coffee beans could be useful.

I've been in your shoes before.

You don't have to throw out your brew after every round.

I teach you how to store your used coffee grounds so they live to see another day.

I talk about the tools you need to effectively complete this task.

I also cover the steps you take to get the finished product.

As coffee lovers, my husband Jack and I pride ourselves on being able to get the most out of our ground beans.

You can find used coffee a lot more helpful than just making your daily cup of joe!

I want to help you waste less and give them purpose!

Let's not waste time and let's get into these tips!

What You Need?
(To Store Used Coffee Grounds)

Before you begin, look and see if you have everything that you need to do this task successfully.

I have a list down below for you to follow. I also put an alternative to each!

Cookie Sheet

This is for spreading out your joe. You can also utilize a baking dish.

I quite like the cookie sheet, as you can ensure that your brew is done and spread them out more evenly.


This is to help drain your espresso. Alternatively, you can choose the sun or newspapers.

Both methods are wonderful, but the oven is always available.

The sun is not always around.

Furthermore, not everyone has an abundance of newspapers lying around.


For this, just make sure that they are air-tight.

Grab any empty containers that you have lying around for this.

I don't recommend zip-up bags as every time you open them, air is let inside.

Methods Of Drying Coffee Grounds

Now I tell you how to dry your coffee grounds.

There are a couple of different ways to do this. I cover them both in this section.

Method 1 # Using The Sun

Of course, using nature is always an option! Here is what you need to do:

  • Place 2-3 inches of ground beans on a baking sheet or another flat surface with newspaper underneath.

The newspaper further helps to drain the grounds of moisture.

Pro Tip

Find some sort of mesh or old screen door to break up bigger coffee clumps and help air circulate through the pile!

  • Find a place that gets the most sun and sit your baking sheet there.

You want to do this the process goes by faster.

Bugs and other critters don't like coffee, so they won't dare to go near it!

Pro Tip

If you can't go outside, you can place them on a counter where the sunlight shines the most . 

  • Leave them out for 2-3 days. Mix them every once in a while to rotate the used coffee.

Make sure that if you put newspaper underneath to change it once a day.

This keeps mold from forming!

Also remember to bring them in when the weather changes!

Method 2 # Using The Oven

If you can't go outside at all, the oven is another amazing tool. Here's what you need to do:

  • Preheat your oven to 200 degrees. Don't go any higher or you'll run the risk of burning your grounds!
  • Spread on an unlined baking sheet.

Pro Tip

Similar to the sun method, only put about 2-3 inches of coffee beans . This shaves time off the process.

  • Place sheet in the oven for 20-30 minutes, mixing every 10 minutes (set a timer if you have to!) to help distribute the heat .

  • Once done, remove them from the oven and let them cool off completely !

Pro Tip

Don't store them directly out of the oven. This only lets moisture accumulate from the steam!   

Storing Your Grounds

Now that your used beans are dry, you need to store them!

You can't just leave them on the baking sheet (although that would be easy, it’s not ideal)!

1. Perfect Packaging

If you don't have any glass or plastic airtight containers, you need to consider packaging them in paper packaging.

And if you end up with so many you don't know what to do with them, you can easily turn it into a small business.

Many gardeners (among others) are looking for dried caffeine! Here's how to package them:

  • Get a paper bag the size of your choosing.

Pro Tip

If you're selling, you can stamp your own logo on the bag!

  • Place them into the bag. Then pack it down until its flat.
  • Fold the open end of the bag under. Then fold it in half.

Pro Tip

You can write marketing information on the back if you're selling it. You can also write the date you packaged them on the back!    

  • Find strings to wrap around the bag and tie securely.

2. Perfect Storing

Alternatively, you can keep your grounds in any empty, clean container.

Here's what to do:

  • Ensure your container is clean.

Pro Tip

It can be glass or plastic. Make sure it is airtight as well!    

  • Take the dried joe and carefully put them into the container.

Pro Tip

A measuring cup or large spoon helps avoid making a mess!

  • Place a piece of newspaper on top.

Pro Tip

This helps to absorb any extra moisture and keep your grounds fresh for longer!     

  • Store in a cool, dry place.

  • Check every 1-2 months!

Pro Tip

Change out the newspaper and check to make sure they are still dry!      

How Long The Your
Used Coffee Grounds Last?

You need to follow the tips above to get the most out of your ground coffee.

Doing this, they can last from 1-2 years !

Just remember to:

1. Find an airtight container.

2. Clean the container beforehand.

3. Put a newspaper on top to mop up any extra moisture.

4. Check them every month or two to make sure the caffeine is still dry.

I am leaving two videos below.

One shows you how to dry your grounds.

The other shows what the dried beans should look like once they are stored!

Once they are stored, put them to good use!

Ground beans are helpful for many different things like gardening and even a facial scrub!
