So, it’s always important to understand what the shelf-life is of a specific coffee product. At the same time, it’s also important to know precisely how to take care of coffee and when coffee has gone bad.

Did your coffee go bad?

It’s incredibly difficult to decipher visually whether or not coffee is going bad because coffee never really changes until you actually brew it. Old coffee beans will look the same as fresh ones.

With that being said, there is one way that coffee drinkers can quickly figure out whether their coffee is starting to go bad. What’s one characteristic of coffee that all java drinkers love? The scent!

The aroma of coffee is such a distinct scent and if your ground coffee are losing it’s powerful aroma, chances are, it’s either incredibly weak or old.

Here’s the sort of silver lining. If you were to accidentally brew a pot of coffee with old coffee grounds, it will not harm you. It’s not going to taste very nice, though.

How do you store coffee to preserve the taste and aroma?

Are you wondering how you can store your ground coffee or beans so that you can preserve that delicious taste and mouthwatering aroma?

It’s important to know that the moment that your grind beans into ground coffee, it will begin to lose its taste and aroma because the gases start to dissipate and the compounds begin to degrade.

The best way to enjoy coffee is to grind it just before you brew and store your coffee as coffee beans.

To take this a step further, what we want you to do is consider looking at ground coffee as a spice. If you are not familiar, the best way to take care of any spice is within a tight, vacuum sealed if possible, container.

Once stored in a air-sealed tight container, there are a few different ways to store it to extend it’s flavor and aroma.

Freezer Method

This might come as a shock to many coffee drinkers; however, did you know that storing your coffee beans in the freezer can help preserve the flavor and aroma and increase the shelf life? Just make sure it’s stored airtight, otherwise it will absorb any aromas in the freezer.

Cabinet Method

The most common method that people use to store their coffee is the cabinet method. Typically, people will store coffee beans and in a regular tin container in their cabinets. It’s important to only store coffee grounds and beans in the cabinet when they are in proper coffee storage container.

What’s the shelf life of brewed coffee?

In this article, we covered ground coffee and how to know when it’s bad and how to properly store it. However, If you are like most coffee drinkers, you still might be wondering, what about my brewed cup of coffee – does that go bad too?

With that being said, it’s evident that brewed coffee will go bad much faster than any other form of coffee given that it’s already prepared, and potentially has milk or creamer in it.

If it has milk, it won’t last more than a few hours. If it’s black coffee, the most you can stretch it to is a day, but even then, why drink old coffee? Just use it as fertilizer for a plant and brew a new cup!

Here are some neat methods to keep coffee hot(and fresh) for as long as possible.

4 Tips to Keep Coffee Fresh

The best way to enjoy any morning cup of coffee is when it’s fresh and the aroma fills the air. Now that you are caught up to speed with everything that has to do with coffee going bad, we thought it would be a great idea to share some useful tips to keep your coffee fresh for longer.

Here are 5 quick tips to keep your coffee grounds fresher than ever before!

1. Avoid Moisture

One of the best ways to keep your coffee beans and grounds fresh is to avoid moisture during the storage process. The best way to avoid moisture is to purchase containers that are designed to keep moisture and air out. If you are not careful, you risk the flavor and the aroma of the coffee spoiling and aging quicker.

2. Avoid Pre-Ground Coffee

If you are looking for a fresh cup of joe, avoid pre-ground coffee at all costs. The best way to ensure the freshest batch of coffee grounds is to purchase fresh beans from a coffee store and grind them right before you brew.

Again, as we discussed earlier in the article, it’s recommended to only grind enough coffee beans per pot of coffee you are brewing. This is to ensure the purest and strongest form of coffee.

3. Utilize the Right Containers

While it might seem evident, utilizing the right containers is essential for storing coffee grounds. It’s highly advised to only use air-tight containers. Ideally, use ones designed for coffee.

4. Avoid Heat

If you want to keep your coffee grounds fresh, keep your container or bag away from heat at all costs. It’s advised to store your container in a cooler area, whether that be the freezer or a cabinet where it’s naturally cool.

When you place coffee grounds in an area where it get’s warm, it can compromise the oils and the strength of the coffee, making the grounds age faster than normal.

Conclusion

Any true coffee aficionado would tell you that it’s essential to know your coffee. We are talking about understanding the roast, expiration date, freshness, style of bean – everything! On top of this, it’s important to know how to take care of your coffee.
