When it comes to coffee, I’m a bit of a snob. I only like the really good stuff—no instant coffee for me! So, when I found out that my favorite local coffee shop was closing down, I was devastated. I knew that I needed to find a new source for my caffeine fix, but where would I get my hands on such high-quality beans? I did some research and discovered that there are quite a few places where you can buy great coffee. But then another question popped into my head: how long is coffee good for?
After all, even the best beans will go bad eventually if they’re not stored properly. Turns out, there’s quite a lot to know about the shelf life of coffee. In this article, we’ll explore everything you need to know about how long is coffee good for so you can enjoy them at their peak flavor every time!
How Long Is Coffee Good For?
If you’re like most people, you probably start your day with a cup of coffee. But what happens to that coffee if you don’t finish it and it sits out all day? Is it still safe to drink? According to experts, cut apples turn brown because of a chemical reaction that happens when they’re exposed to air. When the fruit is cut, enzymes in the apple are released and react with oxygen in the air to turn the flesh brown.
Coffee can go bad if it’s left out for too long, especially if it’s in a warm or sunny spot. The oils in coffee beans start to evaporate over time, which makes the coffee taste stale.
If you’re like me, you can’t help but make more coffee than you can drink in one sitting. But there’s no need to let your delicious brew go to waste. A good thermos will keep your coffee hot and fresh for hours. And if you want to maximize flavor, grind your beans right before brewing.
Why Does Coffee Go Bad?
When coffee is in contact with oxygen, it undergoes a process called oxidation. This is the same process that occurs when you cut an apple and leave it out for a while.
When coffee is roasted, the chemical compounds in the beans begin to oxidize, which changes the flavor of the beans. This oxidation process is responsible for the bitter taste of older coffee and can also contribute to a stale flavor.
When coffee beans are roasted, their natural oils start to break down and they begin to oxidize. If stored properly, in an airtight container in a cool, dark place, roasted coffee beans will stay fresh for a few weeks.
The surface area of coffee beans increases dramatically when they are ground for an espresso machine. This increase in surface area causes the beans to oxidize more quickly.
When coffee grounds are mixed with hot water, they release their oils, aromas, and acid into the mixture.
This reaction is what creates the delicious flavor of the coffee we drink. But, you don’t want it to happen before you’ve started your brew. If the coffee beans are oxidized before being ground, then your coffee will be a lot less tasty.
As you can probably tell, the temperature of the water used to brew your coffee can have a huge impact on its taste.
The optimal temperature for brewing coffee is between 195 and 205 degrees Fahrenheit. This range of temperature creates a more full-bodied and flavorful cup of coffee than cooler or room temperatures.
Why Does Coffee Turn Bitter?
Did you know that coffee (and tea) continues to oxidize even after it’s made?
If you leave coffee sitting out for too long, it will become bitter due to the chemical reaction between oxygen and the coffee’s oils. To avoid this, drink the coffee as soon as possible or keep it in an airtight container.
This is why you shouldn’t leave your pot of freshly brewed coffee sitting for too long.
If you don’t want bitter coffee, make sure to not over-extract the coffee. This can be done by having the right grind size and not brewing for too long.
If you are making coffee using a French press, be sure to transfer it to a coffee mug or pitcher immediately after it is done brewing. If you let it sit in the press, it may become too bitter to drink.
Stale Grounds Make For Stale Coffee
Coffee is a food item that, like any other, has a shelf life. Be sure to use it before it goes stale!
As coffee grounds age, they become more oxidized. This results in coffee that tastes stale, even if it was just brewed. To avoid this, use fresh coffee grounds whenever possible.
The odor of stale coffee is not reminiscent of rot like spoiled milk but has a neutral smell.
While it’s not dangerous, drinking old, sour, or bitter-tasting coffee isn’t exactly pleasant. If you add milk and let it sit for 2 hours, however, it’s no longer drinkable.
Can I Drink Day-Old Coffee?
We advise against drinking day-old coffee, as it is more likely to be rancid and have an unpleasant smell or taste. Brewed coffee also tends to accumulate mold when kept outside the fridge.
If you must drink day-old coffee, make sure it was kept refrigerated and only consume it if it does not have milk mixed in.
Signs Of Bad Coffee
Since coffee beans are dry food, there isn’t enough humidity for mold to grow. Therefore, you can’t really judge your coffee by its appearance.
If you want to check if your coffee is still fresh, the best way to do it is by using your nose and taste buds. Bad coffee will have lost its pleasant aroma, and the flavor will be stale when you drink it.
How Long Can You Keep Brewed Coffee In the Fridge?
You can store leftover, fresh-brewed, or ground coffee beans in your fridge for up to one week. However, the flavor and aroma of the coffee will deteriorate over time.
You’ll want to make sure to cover your coffee cup or carafe if you’re storing it in the fridge. This will help keep your coffee from absorbing any unwanted smells or flavors from other food and drinks inside the fridge.
How Long Is Coffee Good For With Milk?
If a dairy product or coffee has been sitting out for more than two hours, it is not recommended to consume it according to the US FDA.
If you plan on adding milk to your coffee at a later time, be sure to store it in the fridge. This will help keep the milk from spoiling and ensure that your coffee is still fresh.
How Long Is Coffee Good For – Conclusion
So, there you have it! Everything you need to know about how long is coffee good for. Now that you know the answer to this important question, you can enjoy your favorite beans at their peak flavor – every time!
