But First, Do Coffee Grounds Really Go Bad?
Ground coffee is a perishable food item indeed, so it is susceptible to developing a pungent odor and rotting. If you don’t store your coffee the right way, it’s bound to lose all that flavorful, rich taste and bold aroma. In simple words, your morning brew is then going to be flat.
And the right way includes keeping elements like oxygen and moisture away from the coffee grounds. Because these tend to interfere with the chemical arrangement of the coffee. And when the chemical composition gets disrupted, your freshly brewed coffee is sure to smell and taste nothing like anything close to a good cup of coffee.
So if maximum quality and flavor retention are on your mind, then store ground coffee in a container with an airtight seal. And keep that container in a dry, cool place (more on storage later).
Also, if your fresh brew has been just sitting out for an hour, it’s certainly going to lose its delicious, rich flavor. Just saying!
So What Really Happens If You Drink Expired Coffee?
Moving on to the risks involved with consuming coffee made of expired grounds.
The Sell-By Date or Roast Date printed on the label of your ground coffee has passed. Does that mean you’re going to fall sick if you use those very same grounds for brewing coffee? Nope, you’re certainly not going to fall sick. But you aren’t going to appreciate the smell and taste of your coffee either.
Whatever the case, consuming spoiled coffee that is developing mildew or mold is never a good idea. Even when the growth of mold hasn’t spread from the container to the grounds! What mold does is encourages the formation of bacteria, which is most likely to make you sick. And then there’s the possibility of mold producing poisonous substances and causing serious damage or worsening any existing respiratory conditions.
Keeping that in mind, it’s best to purchase your favorite coffee grounds in small batches. This way, you can use it all up before reaching the expiry date. Generally, store-bought coffee grounds should be consumed within 2 weeks.
How Long Does Ground Coffee Last?
The thing about ground coffee is that it can last for a very long time. But then this doesn’t mean that the flavor won’t deteriorate over time.
The shelf life of ground coffee.
- Opened ground coffee in the pantry – Use-By Date + 3-5 months
- Unopened ground coffee in the pantry – Use-By Date + 3-5 months
- Opened ground coffee in the freezer – Use-By Date + 3-5 months
- Unopened ground coffee in the freezer – Use-By Date + 1-2 years
Now it goes without saying that how you store your ground coffee as well as the bean quality has an impact on the final taste of your brew. This means premium quality ground coffee sealed properly in a container with an airtight lid for storage is going to retain maximum freshness for the longest time.
Freezing your coffee grounds is also an option and a very useful one in case you happen to have bought a large quantity of coffee. The best part about freezing is that it keeps the fresh quality and taste intact for months (longer than just pantry storage).
Also take into account the Use-By and Roast Date if you’re genuinely interested in keeping the bold, rich, and delicious flavor of your favorite ground coffee unscathed. In that context, it would be so much better if you bought coffee with the closest or nearest Roast Date. Because, no doubt, coffee tastes the best when it’s brewed within 14 days of the roast date.
As for the Use-By Date, that’s the time until when your coffee is going to preserve its peak freshness. Things start to go downhill from there in terms of flavor, taste, quality, and aroma.
Please note that you can still consume coffee past its Roast Date and Use-By Date provided it hasn’t come in contact with moisture, air, or water. But also bear in mind that once opened, all the original freshness begins to decline.
What If Ground Coffee Has Gone Bad – What Are the Red Flags?
There are four surefire telltale signs that point in the direction of coffee grounds gone bad.
Fresh coffee has a deep and rich black color. But then, during storage, this color can change to brownish blue. When the coffee grounds start to develop a brownish tint, it means they may have gone bad. Although that’s not always the case because the brown tint might also take form due to roasting or maybe it’s just the natural color of the coffee beans.
Any hint of mold on the coffee, packaging, or container means moisture has managed to invade and contaminate the grounds. So throw them away instantly!
We all love the fresh, rich, herby, smoky, and nutty aroma of the coffee, don’t we? Mornings are no good without that crisp, natural scent. But then your brew is smelling musty, which usually happens if you store your coffee grounds for too long. Rancid coffee always has such a funky odor.
If the rotten smell doesn’t get through, then allow your taste buds to decide. You know your fresh brew is stale when it doesn’t have that peculiarly discernible zing of coffee. This means that you’ve either left your fresh brew sitting out for too long (over 30 minutes) or that the very flavor, freshness, and quality of the coffee grounds are spoiled.
How to Keep Coffee From Going Bad? Storing Ground Coffee the Right Way!
Look, not everyone has the time to freshly grind coffee beans right before brewing. More often than not, these are the ones who buy pre-ground coffee i.e. coffee grounds. But then, at the same time, you have to be very vigilant about storage. And here’s how to go about it.
#1. Choosing the Right Container
By right, I mean a container with an airtight seal or lid. And that there should be a band around the opening for keeping air from entering and leaving at all costs.
Also, if this container used to store condiments, spices, etc., make it a point to wash the thing thoroughly because coffee has a porous nature. So it might end up tasting like the condiments or spices you once stored in that jar.
Furthermore, be sure to choose a metal or ceramic storage container in order to also keep away light and heat. But if glass is what you prefer, then go for opaque and not transparent.
#2. Placing It Away From Light, Heat, Moisture
Light and heat surely know how to alter the cell or chemical composition of coffee grounds. That’s how the rich, aromatic coffee oils get lost in the process. Even moisture is a potential contaminant that you must protect your coffee from.
So place the airtight container or jar in the pantry at the back in a cool, dark, dry place. Avoid kitchen countertop storage as sunlight, heat, and water exposure here is the most likely.
#3. Keeping It Bagged
Your flavorful coffee grounds came in quite an attractive or cute packaging that you simply just don’t feel like throwing away. Then you might be thrilled to know that you can indeed store those grounds in the original pouch. However, be more careful in such a scenario when it comes to preventing moisture or air from getting in.
Tie the pouch at the top using a band and then put that pouch into a Ziploc bag for an additional layer of protection against air, moisture, etc.
What About Freezing Ground Coffee?
You can freeze your limited or ample supply of coffee grounds for preserving freshness for the longest time. Coffee remains fresh in the freezer for longer than when stored in the pantry. You’re looking at 1-2 years of storage in the freezer with an unopened bag of ground coffee.
But then the original smoky, nutty flavor, no doubt, is prone to the process of deterioration in the case of long-term storage. So avoid removing frozen coffee and then again putting it back into the freezer as that messes with the peak quality even more. Simply just divide the large batch into smaller units, preferably one unit for one serving.
Once again, store in airtight containers to keep moisture out, thus making sure the coffee grounds don’t go bad.
It’s the lovely, inviting aroma of freshly brewed coffee that many look forward to first thing in the morning. And the thing that makes this possible is fresh coffee grounds, even the pre-ground version of course. This means ground coffee does indeed have a shelf life, meaning it CAN go bad.
So it’s necessary to find out when and how ground coffee goes bad. And how to prevent it from losing all that rich, delicious freshness too soon. When you store coffee grounds the right way, they’re surely going to thank you by brewing the most flavorful cup of coffee for you.
