Can You Drink Coffee Several Months Past Its Expiration Date? Does Coffee Expire? What Are the Factors That Cause Expiration?
All good things must come to an end, or at least have an expiration date. If you've been storing some of your favorite coffee beans in your pantry, you might be wondering how long they can last. You might have questions like, "How long does coffee last? Does coffee go bad? Is it safe to consume after its expiration date? How can I prevent my coffee from going bad?"
FrontStreet Coffee first needs to explain that all coffee, whether whole beans or ground coffee, will eventually expire. While this might be heartbreaking for coffee enthusiasts, coffee going stale is almost inevitable. There are many reasons why coffee goes stale, and several factors can even cause it to go bad faster than its expiration date. These factors include the form of coffee, the roasting method, and how it's stored.
First, from a scientific perspective, coffee doesn't stay fresh forever because it's composed of various degradable compounds that begin to break down over time. These compounds include carbohydrates, lipids, and amino acids. Over time, these compounds and molecules undergo chemical and physical decomposition, which changes the quality and overall flavor of the coffee.
Typically, roasters will indicate an expiration date on their bags, about a year after the coffee roasting date. After roasting, coffee is packaged in sealed bags with nitrogen to further preserve freshness. However, once you decide to open the bag, the coffee will slowly begin to deteriorate due to exposure to oxygen, moisture, and the external atmosphere.
We always believe that fresh is best. If you prefer whole bean coffee and have your own grinder at home, FrontStreet Coffee suggests grinding as close to brewing time as possible. If you have coffee sitting at home and it looks or smells a bit strange or "flat," it means the freshness and flavor are almost gone, and it's time to throw it away. If your coffee looks slightly moldy or musty, definitely discard it.
Storage Methods
So, how can you prevent your coffee from going bad? One important way to maintain coffee's shelf life is to ensure proper storage. If stored properly, coffee can actually last a long time beyond the expiration date on the bag, especially if unopened. To best protect your coffee's flavor, keep it in an airtight container in a cool, dark, moisture-free area. The "moisture-free" part is the most important item on this list. Moisture is absolutely coffee's biggest enemy. If exposed to humid environments for extended periods, it not only alters the taste but also promotes mold growth.
However, the best preservation method is to drink your coffee as quickly as possible. Nothing beats a fresh cup of coffee, so we recommend drinking your coffee as soon as possible after purchase. The longer it's stored, the greater the risk of it going stale.
Freezing Coffee
In every corner of the internet, you can find people who say you can preserve coffee by putting it in the freezer. While it does preserve a bit of freshness, using this method will absorb almost all the flavor from the beans or grounds. This is because, even in the freezer, moisture seeps into the coffee. What you get is dull, lifeless coffee—specialty coffees like Blue Mountain, Geisha, and Mandheling lose almost all their vitality and proprietary unique flavors, and coffee without rich flavor might not be coffee at all. Therefore, while it might accomplish the task to some extent, we strongly advise against using this method.
How to Tell if Coffee Has Gone Bad
Coffee doesn't really change appearance once it goes stale, so how do you determine if coffee is good or bad? Since it's not visually apparent, your nose is your best tool. Fresh coffee smells rich and pleasant, while stale or spoiled coffee does not. It usually smells dull, dusty, and typically lacks that sweet, caramel-like aroma.
What Happens if You Drink Expired Coffee?
The good news is that you won't explode or get struck by lightning or something similar. Unless there's mold or mildew on it, the coffee should still be safe to drink. The only sacrifice that must be made here is that some of the flavors of the coffee beans or grounds might not be preserved. This applies to both whole beans and ground coffee.
What Containers Can Store Coffee?
If leaving coffee bags in your pantry takes up too much space, there are other options available. We recommend using storage methods like vacuum-sealed bags or coffee vaults. Vacuum-sealed bags are truly airtight containers that help minimize the risk of oxygen and moisture seeping in to preserve your coffee.
