How Long Do Roasted Coffee Beans Last?

Coffee is a strange yet very different substance. We couldn’t be more grateful to anyone who invented coffee for making our life taste better. You are doing things with a lot more confidence with coffee by your side.

Without this delicious tasty beverage, which gives you enough courage to go through all the troubles every day, we can not imagine a day without one sip. I know we all use insane amounts of coffee but have you ever wondered how long roasted beans last?

They are going through constant changes in their life cycle, but at its heart-the coffee beans ‘ fragrance and the precious oils that are inside these coffee beans are the best and most important component. You want to keep them as safe and as new as you can.

Yes, even when it comes to coffee, there’s something called an ”expiration date.” Most of us will say it only takes two days to expire (because the coffee is gone by that time and you’re ready for the next shipment of coffee from Amazon). But there are people who actually drink regular amounts of coffee and they might find it useful. Yes, they are people who do not drink all of their coffee, you might be one of them.

Experts in the coffee industry can only agree on one thing-changes in coffee. Very rapid, particularly when exposed to oxygen. Coffee is a really volatile product in nature so you need to follow those rules in order to use coffee in the right way.

What does “freshness” mean in coffee?

First, we need to establish a shared understanding of what freshness means and how we can use it for coffee.

If you ask me about “freshness,” I ‘d just say it refers to a condition or moment of a food or raw material similar to some kind of original state. For example, fruits or vegetables sold on a farmer’s market are generally considered very fresh because the harvest date is very close to when the product is offered.

Now, how to apply this to roasted coffee? Freshly roasted coffee typically means just a few hours or days have passed since the coffee was roasted and taken off the drum.

At that moment, perceiving the incredible aroma complexity is great. In specialty coffee and small-batch roasting projects, we were very fascinated with providing the freshest coffee and taking advantage of the “freshness” appeal.

As a result, the closer the coffee is prepared to the roasting date, the stronger it is in terms of flavours. It sounds very clear as it copes with our general perception of what new foods or beverages would be like (see above).

But coffee’s slightly different.

There are basically two ways to see coffee freshness:

  1. From an aromatic perspective
  2. From the viewpoint of CO2

To grasp this and how it affects coffee brewing, we need to take a break and dive into the roasting process itself.

Regarding aromas, a chemical reaction called the Maillard reaction creates most of them during the roasting process. Don’t worry, I won’t go into chemical depth here because I’m not a scientist, but it’s essentially the same reaction that occurs when you toast bread or make “caramelized” onions for your burgers.

These aromas are great, and once the coffee beans leave the drum, we can see them all at once. And from this point on, aroma intensity begins to drop, which can happen very quickly. This depends on how well you store your coffee.

One thing that happens during beans roasting is that carbon dioxide ( CO2) is produced that begins “leaving” beans. It is called degassing, and it’s the very key point for brewing coffee.

How long is coffee good for after roast date?

Degassing is influenced by ambient temperature, humidity, storage containers and other factors. Generally speaking, most roasters would advise you to wait 3 days to a week after the roast date before enjoying the coffee.

Can you drink coffee too soon after the roast?

Your coffee will reach peak quality for brewed coffee between 20 minutes and 3 days for espresso.
Generally it’s not a smart idea to brew coffee with beans already ground for reasons I’m about to go over. Your roaster should give them a resting period before selling them.

The roasting process heats beans to very high temperatures.

We ‘re talking about a 400F heavy dark roast. You ‘re basically frying them. This creates lots of latent carbon dioxide ( CO2) in beans that wreck your brew ‘s taste.

After the roast is done, it slowly escapes – about 40% of CO2 will have left just the first day after roasting.

The bloom, where you place a small amount of hot water in your ground coffee and let it rest a minute before boiling, is to further help rid the CO2 coffee.

The earlier you brew your coffee, the larger you’ll probably see after the roast. Create a brew the day after roast and if you’re using the pour over coffee maker, you’ll see the fizzy coffee bubbles!

Indeed, this is the best way to be sure your coffee is fresh.

No blooming? It’s going to be dull.

Now, if you brew your coffee too early after the roast, you’ll probably get a big bloom, but also bad flavors that go along with the CO2 and other things that come from the roasting. It’s quite doubtful that most roasters would sell you coffee beans that aren’t good yet or at least without telling you they need a few days of ‘rest’ before they’re good to drink.

However, if you brew your own, you’ll want to experiment with how long you ‘re giving your beans.

You can see their expiration date when you buy coffee beans, but as always, there is more than just a date. It’s all about freshness-the closer the date of roasting, the more aromatic your beans become.

The best taste will come within 2-10 days of roasting the beans. Coffee stays fresh and retains much of their flavor until about 30 days after roasting. After that and in most cases the beans would be considered dry.

How long the freshness of the coffee lasts often depends on roaster processes such as the packaging. There are few well-known ways to package coffee which can kill oxygen and avoid stale beans.

Lavazza, for example, saves coffee beans by flushing the oxygen away and thus temporarily solves the problem of bad coffee. We say temporarily because oxygen finds its way into and starts its dirty work as soon as you open the bag, stealing the coffee flavor and soaking valuable oils out.

Trust your heart, Sherlock. I know the concept of bad coffee beans in your house sounds like mission impossible-but hey, sometimes it sounds like that. The pleasant aroma is gone, and most of the taste. Before you get moist and oxygen to your favorite beans-they leach the coffee oil slowly. The older the beans are, and the less pleasant they will taste if they aren’t properly stored.

 How can you tell if coffee is rancid?

If it looks or tastes a little “wrong” (moldy, rancid, or mildewy), throw it out. If it just tastes dry, it will taste bland, as the coffee scent is such an important part of its flavoring profile.

How should you store your coffee beans properly?

Instructions for storing your precious coffee beans properly are in just a few simple rules–store them in a cool, dry area and keep the bag tightly sealed.

Once you have opened your freshly roasted beans oxygen begins to play its part. Moisture and oxygen are the worst enemies of coffee and they start a brewing process and extract all the precious flavor once they come in contact with it. The sad truth is that, over time, all the coffee will fail–and you can only delay this process for some time. Degradation is more rapid depending on the surface area. So this is the great news that coffee beans are always the best choice compared to ground coffee. When appropriate, you can always grind the coffee and have fresh taste.

With few easy hacks, you can improve the shelf-life. First and foremost: you can move your roasted coffee beans to a canister with an airtight seal that blocks out all light.

You might have heard some stories about keeping your coffee in your refrigerator. Due to temperature fluctuations, it is definitely not recommended to store them, coffee is very volatile so it could affect the coffee’s taste and flavor.

Freezing coffee, on the other hand, is a bit different story–coffee may lose some of its distinctive flavors through this process, and it is recommended in just one case. If you are unable to buy your coffee beans within three weeks. Freezing your coffee beans, the same rule should be followed as for storing them in your pantry, use sealed airtight container.

Can expired coffee hurt you?

Like other dry food products, coffee has a best before date which is merely a recommendation as to how long the coffee will taste good for. It doesn’t actually mean that the coffee expires, as dairy products say. And drinking coffee far beyond this date isn’t going to harm your health or make you sick.

Does coffee expired data matter?

The closer to the roast date, the better for filter-brewed coffee. Think of it as a healthy steak to let sit. With coffee, there’s plenty of gas trapped in there, so it’s necessary to let it rest for 24 to 48 hours.

Espresso is different, and most cafes let beans rest for five days for espresso drinks. Otherwise, due to carbon dioxide release, customers can taste any extra salt or find tiny bubbles bursting in their latte art.

Here’s what you should do

  • Find the beans’ roasting date
  • If you have the quality beans, try brewing the beans over various days (whatever brewing process you ‘re using) to get a notion of how long the beans have to rest, there’s no general law, and coffee and roast differ.
  • Expiration dates don’t matter when assessing the flavor consistency of the coffee
  • Store coffee properly, particularly to maintain aromas
  • Purchase small quantities and eat them in ample time to get the best taste. Monitor how much coffee you need over time.

How long until coffee is no longer drinkable?

Coffee is surprisingly consumer-resilient. Leave meat out for a day, cheese out for three, and bread out for over a week, and you’ll experience the inevitable spoilage of a billion lifestyles enjoying a banquet on your once pristine food.

Coffee, on the other hand, will last years and not spoil.

So if you have some coffee that’s been in your home for 6 months or a year or even longer then it’s drinkable, it’s not going to kill you, but it’s a long way from the optimum flavor. If you’re curious how long you should hold coffee on that kind of timeline, you’ll want to take a trip down to the segment about putting coffee in a freezer.

Why don’t coffee go bad like other consumables?

Okay, the first explanation is that coffee lacks calories, bacteria and other nasties actually have very little room to feast on.

The second explanation is that caffeine is a known poison for many lifestyles, so they steer clear. I’ve always found it amusing how natural protection against insect predators was the favorite psychoactive drug of mankind!

Conclusion

If you’re drinking coffee even after the expiration date and all the flavor is gone–it’s a minor health risk but we think the real thing should be enjoyed by real coffee junkie. Total taste, beautiful scent and satin-like feel. Now you know how to keep your beans safe-less oxygen means more taste!

Self-proclaimed coffee drinker. I would, on a typical day, start my day by grinding my coffee with a manual grinder and use a French Press as a starter (2 cups), then a pour-over in the afternoon (4 cups). I had my fair share as a barista but I prefer to drink it, not serve it.
