Will coffee expire? what is the reason for the expiration of coffee? how do you know that coffee is bad?

All good things come to an end. Or at least one expiration date. If you keep some of your favorite coffees in your storeroom all the time, you may want to know how long they can be stored in this way. And there will be the question, "how long will the coffee last?" Will the coffee go bad? Is it safe to eat once the shelf life is exceeded? How can I keep my coffee from spoiling? "

Will the coffee expire? What is the factor of expiration?

All coffee, whether whole beans or ground coffee powder, will eventually expire. Although this may be a little heartbreaking for coffee fans, coffee deterioration is almost inevitable. There are many reasons why coffee goes bad, and there are several factors that may even cause it to deteriorate faster than its shelf life. These factors include the form of coffee, the way it is roasted and the way it is stored.

First of all, from a scientific point of view, coffee will not stay fresh forever, because coffee is made up of a variety of biodegradable compounds that begin to decompose over time. These compounds include forms of carbohydrates, lipids and amino acids. Over time, these compounds and molecules undergo chemical and physical decomposition, thus changing the quality and overall flavor of coffee.

Usually, roasters mark the expiration date on their bags, about a year after the roasting date. After baking, the coffee is packed in a sealed bag with nitrogen to further keep it fresh. However, once you decide to open the bag, the coffee will slowly begin to decompose due to exposure to oxygen, moisture and the external atmosphere.

We always believe that freshness is the best. If you like whole bean coffee and have your own bean grinder at home, Qianjie coffee is recommended to be ground as much as possible when brewing. If you have coffee at home, and it looks or smells a little strange or "flat", it means that the freshness and taste of the coffee are almost gone, and it's time to throw it away. If your coffee looks a little moldy or moldy, be sure to throw it away.

Preservation method

So, how can you keep your coffee from going bad? An important way to maintain the shelf life of coffee is to ensure that it is stored correctly. If stored properly, coffee can actually be preserved for a long time after its expiration date on the bag, especially if it is not opened.

To best protect the flavor of the coffee, put the coffee in a sealed container in a cool, dark, moisture-free area. The "anhydrous" section is the most important part of the list. Water is definitely the worst enemy of coffee. If you are exposed to moisture for a long time, it will not only change the taste, but also promote the growth of mold.

However, the best way to preserve it is to drink coffee as soon as possible. There is nothing better than a cup of fresh coffee, so it is recommended to drink coffee as soon as possible after buying it. The longer it is stored, the faster it is at risk of getting dirty.

Frozen coffee

In every corner of the Internet, you can find people who say you can keep your coffee in the refrigerator. Although it does keep a little bit fresh, using this method will absorb almost all the flavor from the beans or the ground. This is because even in the refrigerator, water seeps into the coffee.

The result is dull coffee, such as Blue Mountain Coffee, Rose Summer Coffee, and boutique coffee with unique flavors such as Manning, which have little vitality or unique flavor, and coffee without rich flavor may not be coffee at all. Therefore, although it may have done the work to some extent, we strongly recommend that this method not be used.

How do you know the coffee is bad?

Once the coffee goes bad, it doesn't really change its appearance, so how do you judge whether the coffee is good or bad? Since it is not visible to the naked eye, the nose is a good tool. Fresh coffee smells rich and pleasant, while old or spoiled coffee is not. It usually smells dull, dusty, and usually lacks the sweet caramel-like aroma.

What happens if you drink expired coffee?

The good news is that you won't explode or get hit by lightning or something like that. Unless there is mold or mold on it, coffee should still be drinkable. The only sacrifice that must be made here is that some flavors of coffee beans or coffee powder may not be maintained. This applies to whole beans and ground coffee.

What container can hold coffee?

If the coffee bag takes up too much space in the storeroom, there are other options. We recommend using storage methods such as vacuum sealed bags or coffee stores. The vacuum sealed bag is a truly airtight container that helps minimize the risk of oxygen and water infiltration to store coffee.
