How To Store Coffee Grounds For Maximum Freshness


No one has the time to grind their coffee beans each morning freshly. It’s a tedious chore that takes up too much time in this day and age, but there are some ideas you can keep in mind for storing your coffee grounds and ensuring that you still end up with a beautifully aromatic cup of coffee before your day starts.

Freezing your ground coffee can prolong the freshness as long as the temperature doesn’t fluctuate. Optimal conditions include ceramic and glass airtight containers. Vacuum-packed bags also extend freshness. Coffee grounds should be stored away from heat, light, and moisture.

If you are part of the fast-paced, caffeine-high generation, you depend on pre-grinding your coffee and storing it as best possible to ensure its maximum freshness. But how do we ensure we get the freshest ground coffee achievable?

What Is The Right Way To Store Ground Coffee?

How to Store Coffee Grounds

If you use your coffee grounds daily, storing them in an airtight container, preferably ceramic or glass, in a dark room away from moisture and heat is best. Fluctuating temperatures in the container draw in water that adversely affects the flavor of the coffee and causes it to lose its freshness.

Your coffee grounds can be frozen in a vacuum-sealed container that separates it from the moisture and odors around it. Ground coffee is susceptible to absorbing dampness and odors in the air around it, which decreases its freshness.

What Elements Impacts The Freshness Of Ground Coffee?

The freshness of your ground coffee is regularly impacted by elements such as heat from direct sunlight or heat-excreting appliances like a stove or an oven.

Trapping oxygen and CO2 in a container that is not airtight also affects the levels of the coffee’s freshness and causes the coffee to become stale and dried out.

Fluctuating moisture levels, jolted by freezing and unfreezing ground coffee, make the coffee taste flat and moldy. This is a significant issue and should be considered by not storing your coffee grounds in your fridge.

Can I Keep Ground Coffee In The Fridge Or Freezer?

Keeping ground coffee in the fridge is a huge no. However, you can keep it in the freezer. Here is why:

  • Ground coffee is unfavorably impacted by humidity. Holding your ground coffee in the fridge allows you to open it more often, introducing more moist air to the coffee granules. If it’s in the freezer, it stays fresher longer because the airtight seal is less likely to break.
  • Placing the ground coffee in the freezer involves typically storing it in an airtight container or a vacuum-sealed bag. This locks in the flavor of the coffee and maintains its freshness.
  • Since ground coffee absorbs moisture and odors in the air, placing it in the fridge will allow it to act as a deodorizer. It will soak up the fragrances in the fridge and negatively impact the flavor and freshness of your ground coffee.

Why Do Coffee Grounds Go Moldy So Quickly?

Coffee beans are incredibly proficient at absorbing and retaining moisture. With the added capacity of trace natural minerals and nutrients, damp coffee grounds are a breeding ground for mold and algae.

Simply placing your coffee grounds in the fridge will introduce moisture and odors from the cool, fresh air. The damp environment will permeate your coffee grounds and generate a natural breeding ground for mold. So too, store your coffee grounds in an unsecured container at room temperature where the moisture in the air and the minerals are ideal for mold to form.

How Can I Keep Coffee Grounds From Molding?

Keep your coffee away from humidity to maintain a mold-free batch of coffee grounds.

Stash away your ground coffee in an airtight container away from heat exposure. Or vacuum pack it and keep it in the freezer, where the temperatures are too low for mold to form.

How Long Does Ground Coffee Last Once Opened?

Coffee grounds are freshest within the first week or two but can remain fresh for at least three to four months after opening the sealed packet. Unfavorable factors that will affect the freshness are heat, light, and moisture.

A vacuum-sealed bag in the freezer can preserve its freshness for up to one or two months. Sealed packets of ground coffee typically remain fresh until the best-by date. Some believe keeping the opened bags between 30 – 45 days is best.

Does Ground Coffee Have An Expiry Time?

Ground coffee does have an expiry time. However, you can take precautions to avoid fluctuating temperatures and humid environments. Coffee grounds are prone to absorb moisture from the air and, if not stored correctly, will lose their taste after one to three weeks.

However, sealed packets can last up to a few years or as indicated by the best-before date on the package. And even after opening, coffee grounds do not go off as long as it does not become moldy or wet. It will continue to be drinkable, although it will not stay as fresh as the first week or two.

Should You Store Ground Coffee In A Ziploc Bag Or A Glass Jar?

Ziploc bags do not provide adequate barrier protection and will not keep moisture out of the container. A Ziploc bag can be vacuumed from any protruding humidity in the air but will not stay impenetrable.

You can rather store your coffee grounds in a glass jar. The best option is to choose a container with a sealable lid to separate the moisture from the coffee. Since coffee grounds are so adept at absorbing the condensation around them, you should opt for an airtight canister made from glass or ceramic.

Can You Store Ground Coffee In Plastic Containers?

Like the Ziploc bag, a plastic container or Tupperware is not as airtight as required to preserve your coffee grounds’ freshness. Plasticware is not ideal for storing ground coffee because it allows moisture and light to invade the container and introduce factors that cause mold to develop or flatness to the coffee taste.

However, if your plastic container can be sealed tightly, it should be safe enough to lock in the freshness of your coffee grounds for a week or two. Over more extended periods, the coffee flavors will seep into the plastic and aromatically contaminate any future coffee you store in there.

How To Store Coffee Grounds In Containers

  5. Before closing the lid, include a piece of newspaper to absorb any potential dampness that might hover in the jar.
  6. Store your jars of ground coffee in a cool, dry place in the pantry or a cupboard to avoid direct heat exposure.
  7. Regularly check your jars and replace the newspaper This ritual will extend the shelf life of your coffee grounds immensely.

  • Lock out any moisture. Avoid exposure to damp areas in the kitchen, like the fridge and shelves above your stove.
  • Pre-grind your coffee beans and store your ground coffee in airtight containers or a vacuum-sealed bag in the freezer.
  • Keep it in a cool place at the back of the pantry. Ensure your ground coffee is away from direct sunlight or heat.
  • Choosing a suitable container will assist with sealing in the freshness and aromas of the ground coffee. Opaque ceramic or metal canisters are the favorite choices to store your coffee, but the glass also works well.

How To Know If Your Ground Coffee Is Still Good?

When coffee is exposed to moist conditions at constant high temperatures, it becomes a breeding ground for fungi like coffee mold. Drinking moldy coffee can be dangerous to both your short-term and long-term health and causes symptoms like dizziness, headaches, anxiety, and irritability.

The only factor that will make coffee undrinkable, though, is when it develops mildew. However, coffee doesn’t go bad. It will simply lose its flavor or start to smell and taste flat. It often adopts a cardboard taste, indicating the coffee has been in unsavory conditions for too long.

When Should You Discard Your Coffee Grounds?

Although coffee grounds have an indefinite lifespan, certain factors should make you throw out your coffee, regardless of how old it is.

  • If your ground coffee becomes lumpy, or if you notice mold in the container or the bag, you should discard it. Drinking stale coffee can cause nasty side effects like nausea, stomach ache, or headaches.
  • If, for any reason, you find insects in your coffee grounds, it is already contaminated, and you should throw it out. It would be best if you did not drink it under any circumstances.
  • Trust your sense of smell before you brew your coffee. If it smells off, flat, or rancid, dispose of it.
  • If the quality is not what you expected from the coffee grounds, rather dispense the coffee grounds and invest in a different supplier. A cup of freshly brewed coffee is very personal and has to speak to you. If you’re not satisfied with the result of your coffee grounds, it’s no use keeping it.
