Freshly pulled espresso shots have a thick crema layer and aromatic flavor. But that irresistible essence fades fast as time passes.
While an espresso shot can last up to a week or more when stored correctly, it is recommended to consume it within minutes.
When we take a sip of Espresso after fifteen or, say, thirty minutes of brewing, the taste of our cup of joe is not as good as we are looking for. So, Does Espresso go bad?
The espresso doesn’t really “go bad” in the sense of being unsafe to drink. However, the taste and texture of Espresso degrades rapidly with time. The thick layer of Crema dissolves in the drink and makes the taste very unpleasant and bitter.

Key Takeaways
- It’s best to drink Espresso within 5 minutes of brewing.
- Espresso doesn’t expire but its taste degrades over time.
- You can refrigerate leftover shots and use them for making Iced coffee drinks later.
- Don’t make the mistake of reheating refrigerated Espresso.
how long does an Espresso shot last?
The answer to how long is Espresso god for is subjective. Some people notice the change in taste in five minutes, while some people can’t sense the taste even after one hour. It depends on how sensitive are your taste buds.

I was curious to know how the taste of espresso changes over time. So, I conducted an experiment and brewed 6 different shots of Espresso.
I drank the shot, which I brewed at the last within 10 to 15 seconds of brewing. This shot has a very satisfying aroma, but it was so hot that I could not fully distinguish among flavor profiles.
I drank the next shot after three minutes of brewing, it was at perfect drinking temperature and much more flavorful, and I loved that.
I drank the next shots by giving a gap of 30 minutes among them. I noticed that the flavor of Espresso gets bitter over time, and the aroma also diminishes with time.
The shot I had at the last was too bitter and stale and I completely hated it.
There is no exact timeline to define how long Espresso stays fresh. As the shots of Espresso never expire, it’s completely fine to drink it even after one day.
But the taste and the texture of Espresso change significantly over time. It gets more and more bitter over time. And the thick layer of Crema you notice over the freshly brewed shot of Espresso also gets mixed in the Espresso.

Why does the taste of Espresso change over time?
You might be wondering why Espresso tastes bad over time. The simple answer is oxidation!
There are free hydrogen ions present in the shot of freshly brewed shot of Espresso. These free hydrogen ions are the reason behind the acidity and the slightly sour taste of Espresso.
As time passes, more and more free hydrogen ions get oxidized, reducing the acidity and raising the pH. As the pH increases, the bitterness also increases.
Oxidation occurs at faster rates at higher temperatures. Oxidation is the main reason behind the spoiling of most food items.

You might have noticed that the slice of apple gets brown if we leave it out for some time. That’s also because of oxidation. But what happens if we store it in the fridge?

The other reason for a change in Espresso’s taste after some time is that the heavier oils and compounds get settled to the bottom of the cup, and lighter compounds move up. And the bitter layer of Crema gets dissolved in the Espresso.
This makes the taste of Espresso inconsistent, and some amount of sludge may appear because of heavier compounds at the bottom.
This problem can be solved by stirring the shot for 15 to 30 seconds.
how long does espresso last in the fridge?
The espresso shot can last in the fridge for a week. So, If you’ve brewed an extra shot of espresso, the best way to preserve its flavor is to store it in the fridge. This will slow the oxidation process.
When storing espresso in the fridge, be sure to cover it tightly with a lid. This will slow down oxidation and prevent it from absorbing flavors from other foods in the fridge.
Don’t reheat leftover espresso; it will taste burnt and ruin your coffee experience. Instead, use it to make a refreshing cold coffee drink.
Here are two ways I use leftover espresso:
- Prepare a delicious Iced Latte out of it. When we add milk to leftover Espresso, the milk’s sugars dissolve the bitterness and make the taste very appealing.
- Freeze the leftover Espresso in an ice cube box and make amazing iced coffee recipes from it.

Is it a good idea to store coffee beans or brewed coffee in the fridge? Check out our detailed article on this topic.
How long do Espresso beans last?
Freshly roasted espresso beans last 1-2 months before the flavor really starts to fade. Espresso fanatics know you should brew beans within 2 weeks of the roast date for optimal taste.
After a month, the beans begin to oxidize and the oils break down, causing the espresso to taste flat and dull.
Pre-ground espresso degrades even more quickly than whole bean since more surface area is exposed to oxygen.
If you’ve already ground your espresso beans, the clock is ticking faster. Ground espresso can only maintain its flavor for a few hours to a week, depending on how well it’s stored.
how long does Espresso last in your system?
The caffeine in espresso takes about 15-45 minutes to kick in and reaches peak levels around 1 hour after consumption when it has been fully absorbed into the bloodstream.
During this time, you’ll experience increased alertness and energy.

Espresso is a great way to start your day or get a boost in the afternoon, but it’s best to avoid it later in the evening, as its caffeine content can disrupt sleep.
Does Espresso Lose Caffeine Over Time?
A shot of Espresso definitely loses its flavor with time, but does Espresso also lose caffeine over time?
No, The caffeine content of an espresso shot remains the same, regardless of how long you store it. Many chemical breakdowns occur in the shot of Espresso, which alters its taste over time, the Crema also dies, but the amount of caffeine always remains the same.
