How Long Does Fresh Ground Coffee Last?

How long your freshly ground coffee depends on a couple of factors, namely how well you stored them and the quality of your coffee beans.

Straight off the bat your premium quality specialty coffee will last for 10 days after their roasted on date before they start to lose the vibrant aromas and flavors.

This is the peak flavor window of coffee which lasts for only one week starting 3 days after they were roasted and for 7 days after that.

To be as clear as water, your specialty coffee will not go off after this time frame; they will just lose the intricate, unique flavors and slowly start to taste like regular coffee.

Stored under normal conditions in an airtight container, your specialty coffee will last for 3 to 4 months, by which time your coffee will taste like regular or low quality coffee.

Regular coffee you don’t need to worry about the flavor or loss of flavor. It will last for the same period of time, 3 to 4 months.

How Long Does Fresh Ground Coffee Last Unopened?

Unopened a bag of fresh ground coffee will last for an extra month beyond the 3 to 4-month period, making unopened fresh ground coffee last for up to 5 months.

This is the same regardless of the quality of your coffee; just don’t expect your premium quality coffee to have their special vibrant flavors.

How Long Does Fresh Ground Coffee Last In A Jar?

Storing your freshly ground coffee in a jar is not an ideal or perfect way of storing your coffee even if it is 100% airtight.

A jar is normally airtight but transparent, meaning your coffee is still exposed to one of the factors that is an enemy to the freshness of your coffee – light.

Also, the jar is likely to be made of glass or metal, meaning it is conductive to heat, another enemy to the freshness of your coffee.

Even if your jar is opaque, there is still the issue of heat and not being insulated from it.

A simple jar doesn’t do anything at all to keep coffee fresh or extend the period in which it will last.

An opaque airtight coffee canister that is purposely designed for the storage of coffee, particularly an airtight opaque vacuum coffee canister, is much better for the storage of your coffee ground or coffee beans.

They still don’t extend the life of your coffee grounds or whole beans. What a professional coffee canister, particularly one that has the ability to create a vacuum, will maintain the flavor.

How Long Does Fresh Ground Coffee Last In Refrigerator?

If you store your fresh ground coffee in your fridge while opened, you risk that it will take on the flavors of the food items in your fridge as coffee is an excellent deodorizer and absorbent of odors and flavors.

This,

if you are curious, is exactly how you make naturally flavored coffee grounds and beans. Simply add the food item, herb or spice to your coffee canister with your coffee and wait 12 to 24 hours.

When you are storing your coffee grounds or whole beans in your refrigerator, you absolutely must use an airtight container to prevent them from absorbing the flavors of food that is in your fridge.

Keeping your specialty coffee in your fridge helps to get an extra day or two from the peak flavor window and maintains their fresh, vibrant flavors for longer.

In all, storing your coffee in your fridge will not extend the life of your freshly ground coffee as it will still keep well for 3 to 4 months. The advantage is an improvement in the flavor and freshness over that period of time.

There are many coffee experts and enthusiasts that don’t recommend storing your coffee in your refrigerator or claim that it adds no advantage at all.

Your fridge works by lowering the temperature to a temperature of less than 5C (41F) and storing your food (your coffee) in a controlled temperature environment. This low temperature reduces the degradation of your food and coffee, by slowing down the oxidation process.

How Long Does Fresh Ground Coffee Last In The Freezer?

If you want to store your freshly ground coffee or whole coffee beans in your freezer, it is essential that you open the package that they came in and store your coffee beans or freshly ground coffee in an opaque vacuum airtight coffee canister.

If you fail or forget to do this, you are risking, and your coffee will likely suffer from freezer burn leading to a degradation of your coffee.

Your freezer will reduce the oxidation process to almost zero, a snail’s pace and extend the life of your fresh ground coffee to 2 years.

Don’t use your freezer for your day to day coffee. Use it for long term storage. It is detrimental to your coffee if you are opening your coffee canister that you keep in your freezer every day to get the coffee you need to brew your cup of coffee.

Have a second coffee canister that is opaque, airtight and has the ability to make vacuum and fill this second canister with enough coffee to last you two weeks and refill it every two weeks with coffee beans from your freezer.

That is what I call optimal storage of your coffee.
