Ground coffee provides convenience without sacrificing the distinctive flavor of a freshly brewed cup. It is already crushed and ready to be brewed at a moment’s notice.
Although you can prolong the freshness of ground coffee, it won’t last indefinitely, like all good things in life.
So, keep reading to learn how long ground coffee lasts, some indicators of bad ground coffee, and what you can do to extend its shelf life.
Can Ground Coffee Go Stale or Bad
While it doesn’t rot or smell, ground coffee can sometimes go bad. When it does, it will lose its rich aroma and flavor if it is not stored properly.
In fact, when coffee comes in contact with even the smallest amount of water or oxygen, its composition can be altered, releasing the unappetizing flavor and aroma that coffee lovers hate.
In fact, your coffee will lose its flavor even if you’ve let a freshly brewed cup sit outside for an hour.
Ground Coffee Shelf Life
Ground coffee can be stored in your pantry for months without going bad. But its flavor will degrade the longer you store it, even if it doesn’t go bad.
An unopened can of ground coffee stored in your pantry can be used three to five months past its “Best Before” date. In your freezer the same unopened can of ground coffee can be used one to two years past its “Best Before” date.
As for an opened can of ground coffee, stored in your pantry it can be used three to five months past its “Best Before” date. In your freezer, the opened container can also be used three to five months past its “Best Before” date.
Ultimately, your fresh cup of Joe’s flavor is typically influenced by your coffee bean’s quality and storage technique. For example, an airtight container can keep premium ground beans fresher for longer.
In fact, if you have a large amount of coffee grounds, you might want to try freezing them.
Freezing your coffee grounds will ensure it will still taste great even after two to three months of freezing.
Furthermore, the roast date also plays an important role when gauging the freshness of your ground coffee. It is recommended to use ground coffee as close to its roast date to appreciate its rich flavor fully.
Coffee experts believe the optimal brewing time is 7 to 14 days after the roasting date. But again, this will depend on the quality of the grounds and the storage technique used.
Of course, you can still use ground coffee past its “Best Before” or roast date. But, only consider doing that if you’re 100% sure your grounds haven’t been exposed to air or moisture.
How to Tell If Your Ground Coffee Has Gone Stale or Bad
Listed below are a few indicators of stale or bad coffee grounds.
Presence of Mold
Start by scanning the container, packaging, and coffee grounds themselves for signs of mold. Mold formation occurs on coffee grounds when air or water seeps into your container.
If you see any mold, immediately discard the coffee grounds as they are unsafe for consumption.
Change in Taste
The best way to ensure your coffee is fresh is to brew a hot cup and taste it. At the end of the day, the aroma and taste of a freshly brewed cup is the easiest way to identify freshness.
Coffee grounds beyond their prime won’t have the distinctive zing that makes them so well-liked.
Furthermore, remember that your freshly made coffee will begin to lose flavor if you let it sit for longer than thirty minutes.
Therefore, ensure that you sample the coffee immediately to determine whether it was made using fresh or stale ground coffee.
Change in Color
The deep black, rich color of freshly ground coffee may turn brownish if it is kept in storage for an extended period of time.
But a brown tint doesn’t always mean that your ground coffee is spoiled. Instead, it could be due to the roasting process or the result of brown coffee beans.
Change in Smell
You cannot determine whether coffee has gone bad just by looking. Smell the coffee again to check for any odd smells. A good cup of coffee will smell smoky, nutty, and herby.
However, if coffee has been exposed to dampness, it may begin to smell musty and lose its freshness.
Long-term storage of coffee can also result in oils in the beans going rancid, giving your cuppa a foul odor.
How to Store Ground Coffee
Most coffee lovers concur that freshly ground coffee has a significantly better flavor and aroma than pre-ground coffee.
But pre-ground coffee is useful when you don’t always have the time or energy to grind fresh coffee whenever you want a cup of Joe.
In fact, your pre-ground coffee can be just as good as freshly ground stuff if properly preserved.
The best thing to do here is to store it in a container with an airtight lid.
Freezing coffee grounds is another topic that includes a lot of controversy. But first, let’s learn how to store your ground coffee properly.
Some people believe freezing coffee grounds reduces their flavor; in some cases, they are right. It is especially the case if the grounds are left in the freezer for an extended time.
But, if you have a lot of coffee grounds, you can freeze them. In fact, they will taste just as delicious as coffee that’s been kept at room temperature in a pantry.
Keep Them Bagged Up
Let’s be honest; there are times when you don’t want to get rid of that good-looking pouch of coffee you just purchased.
Of course, it’s fine to use the coffee grounds’ original packaging for storage. However, it would be best to exercise extra caution to avoid moisture and air from getting inside the bag.
After you’ve opened the coffee bag, an excellent tip would be to close the pouch’s top with a rubber band before putting it in a Ziploc bag.
It provides the coffee grounds with extra defense against air and dampness.
Don’t Store Them with Other Food Items
Coffee is highly porous when it is in its ground state. So, ensure they don’t absorb the tastes and smells of other stuff inside your pantry or freezer, particularly spices and meats.
If you don’t keep your seasonings and coffee grinds in airtight containers, this is exactly what will happen.
Therefore, you’ll have no choice but to throw your ground coffee out if it tastes like a mixture of ground oregano, rosemary, or nutmeg.
Protect It from External Elements
Once you’ve packed your ground coffee properly, make sure to store it away from moisture, heat, and direct sunlight.
No matter the form, these three things don’t mix well with coffee. The cell structure of the coffee grinds will be altered by heat and light.
It will result in the loss of the oils that give coffee its exceptional aroma and flavor.
Typically, the back of your pantry is the best place to store ground coffee. Furthermore, you can also store it on your countertop for easy access. But ensure that they’re in the right container.
Select the Right Container
Whether you store your ground coffee inside your pantry or kitchen top, an airtight container is of the utmost importance. It will ensure your coffee remains protected from moisture and dampness.
However, you can go one step further and look for a container with a tightening band on its top. Moreover, choose metal or ceramic containers to shield the coffee grounds from direct light and heat.
Similarly, if you prefer glass containers, go with an opaque glass container rather than a transparent one.
Downsides of Drinking Coffee Made from Expired Grounds
You won’t become sick by drinking ground coffee that has exceeded its “Best Before” or roast date.
But, the mouthwatering aroma and taste of freshly brewed coffee are two things you will have to give up. Nevertheless, you should never drink coffee with mildew or mold.
In fact, you should discard the coffee even if the mold is only present on the outside of the coffee container. Mold contains bacteria that can harm your health.
Mold can lead to various respiratory issues, vomiting, diarrhea, and death in rare cases. So, if you see mold, throw your ground in the garbage.
Instead, buy your preferred coffee grinds in small quantities. It will ensure your coffee doesn’t pass its “Best Before” or roast date and stays fresh.
Controversies behind Freezing Ground Coffee
Whether coffee should be frozen to maintain its freshness is a subject that divides coffee lovers.
Your coffee grounds can be kept in the freezer for a few days to a month without significantly changing their flavor or aroma.
Having said that, coffee grounds that have been in the freezer for months or years will still be fresh. But they will probably lack room-temperature ground coffee’s smoky, nutty flavor and aroma.
An excellent tip is to avoid taking frozen ground coffee out of the freezer and putting it back in again. Instead, divide your grounds into smaller portions, freeze them separately, and use them all at once.
Ultimately, you can use ground coffee as soon as you take it out of the freezer, unlike whole beans that need to be thawed first.
Although ground coffee has an excellent shelf life, it might lose some of its delightful flavor and aroma over time. Sure, it won’t harm you to drink coffee grounds past their roast or “Best Before” date.
However, it would be best to throw away moldy grounds. Ultimately, with the right storage, ground coffee can remain fresh for a very long period, whether it is stored or frozen.
