After a long slumber, nothing can perk you up in the morning quite like a strong shot of delicious espresso. But if you make your espresso at home, you might be wondering: How long does that bold flavor last? How long is espresso good for?
How long your espresso lasts depends on a few factors, including how you store it and whether it’s brewed or still in ground form.
In general, an espresso shot gives you its best aroma and flavor until 15 minutes after brewing. And an espresso grind may last up to four weeks if you keep it in ideal conditions.
Let’s explore the factors that affect the shelf life of an espresso grind. We’ll also go through the correct process of storing brewed espresso and espresso ground coffee beans.
Factors That Affect the Shelf Life of Espresso
The shelf life of an espresso grind can vary based on several factors, including:
The Freshness of the Beans
Espresso beans offer you their best performance when they’re freshly roasted. As beans age, they lose their flavor and aroma. This is because the roasting process creates hundreds of volatile compounds that give coffee its flavor. Over time, these compounds break down and the coffee loses its flavor.
The grind size is another important factor that may affect the shelf life of an espresso grind. The finer the grind, the faster the espresso will experience a decline in flavor.
In the case of finer grinds, more surface area is exposed to air, which can cause the coffee to oxidize. Oxidation is the process by which oxygen reacts with other substances, which ultimately makes the coffee lose its richness.
Storage Method and Duration
Your storage method is also crucial for keeping espresso fresh. To extend its life, you should store your espresso powder in an airtight container in a cool, dark place.
Exposure to air, light, moisture, and heat will accelerate the degradation of the coffee’s flavor.
The length of time that you keep an espresso grind in storage also has a direct effect on its freshness. The longer espresso is stored, the more its flavor will deteriorate, even if you store it properly.
How Long Can You Keep an Espresso Shot in the Refrigerator?
If you’ve already brewed your espresso but circumstances have forced you to enjoy it later in the day (perhaps an urgent call from work), you can store your espresso in the refrigerator.
But how long can espresso stay in the fridge without getting too bitter?
Well, espresso can still be good for up to 24 hours if you follow a few simple guidelines for refrigerator storage. After that, it’ll start losing its desirable and intense flavor.
Tips for Storing Espresso in the Refrigerator
- Use an airtight container to keep out air and moisture, which can cause the espresso to become stale rapidly.
- Store the espresso in the coldest part of the refrigerator to slow down the oxidation process.
- Don’t go over the 24-hour mark.
- Let the refrigerated espresso come to room temperature before drinking it to bring out its unique flavor.
Can You Keep an Espresso Shot in the Freezer?
What if you’re too busy and want to have your shot of espresso the next day? Can you freeze espresso?
The answer is yes, but you should be fully aware that freezing espresso might change the taste of the coffee drastically. Espresso that has been frozen will be less flavorful and will have a slightly watery taste.
How Long Does Espresso Last in the Freezer?
An espresso shot can be stored in the freezer for up to two months. However, the longer the espresso stays in such severely cold conditions, the more its flavor will deteriorate.
Tips for Storing Espresso in the Freezer
- Use an airtight container to prevent the leftover espresso from absorbing other unpleasant flavors in the freezer.
- Label the container with the date you froze the espresso so that you can better judge how fresh it is.
- Thaw espresso overnight in the refrigerator.
- Avoid thawing espresso at room temperature, as this will deplete the flavor much more easily.
- Drink leftover espresso as soon as you thaw it. If you let it sit out for too long, the espresso will taste more watery.
- Add milk or flavoring to mask the thin taste of your espresso shot. Or, you could use it to make various drinks to make up for the lack of rich flavor, such as iced coffee, lattes, etc.
How to Properly Store Ground Coffee for Better-Tasting Espresso?
If you want to enjoy the full flavor of espresso, it’s important to store your ground coffee properly. So, here are some tips on how to store ground coffee like a pro:
Tip 1: Use a Tightly Sealed Container
This is the most important tip for storing ground coffee. An airtight storage container will prevent the coffee from absorbing moisture and other flavors from the air.
It’ll also protect the coffee grounds from curious insects and pests.
If you don’t have a container that gives you a good seal, you can store ground coffee in a zip-top bag. Just make sure to press out as much air as possible before sealing the bag.
Tip 2: Store the Coffee in Ideal Conditions
As you know, heat and light can cause ground coffee to lose its bold taste. That’s why it’s essential to store the coffee in a cool, dark place, such as your pantry or cabinet.
If you live in a tropical climate (like New Orleans), you may want to consider storing your ground coffee in the fridge or freezer. Bring it back to room temperature before using it.
Tip 3: Store the Coffee in Small Batches
Ground coffee has a shorter shelf life than whole beans. To ensure that the coffee stays fresh, store it in small batches that you will use within a few weeks.
In addition to that, you should label the container with the date. This will help you monitor how long the coffee has been stored and ensure that you’re using the freshest coffee possible.
Tip 4: Use Whole-Bean Coffee for Espresso Instead of a Grind
Whole beans are superior to ground coffee, especially when making espresso. That’s when you want to bring out the best flavor profiles in the coffee. So, consider buying and storing whole beans instead of espresso grinds.
You can follow the same storing steps, too:
- Avoid storing whole beans in the refrigerator or freezer.
- If you must, you can refrigerate or freeze them but expect that the beans will lack some flavor after thawing. Bring the beans to room temperature before using.
- Keep the beans in a tightly-sealed container or bag inside your pantry or kitchen cabinet.
It’s always a good idea to grind your beans fresh, too. The fresher the beans, the more complex the flavor of your espresso will be. If you can, grind your beans right before you brew your espresso.
What Happens if You Drink Old Espresso?
If you drink old espresso, it may taste bland or even sour, especially if it is way past its recommended best-by date. Here’s what happens to espresso as it ages:
- The volatile compounds that give espresso its flavor start to break down.
- The coffee beans become stale and lose their aroma.
- The espresso will tastes bland, bitter, or sour, free from pleasant notes.
Drink old espresso and you may even experience some annoying side effects, like nausea, diarrhea, and similar conditions.
In rare cases, drinking old espresso can cause food poisoning. When this happens, the leftover coffee is likely contaminated with bacteria growth or mold particles that may have found their way to a container that wasn’t properly sealed.
Without a tight seal, moisture can easily seep into the spaces between your coffee granules or beans, inviting mold over.
If you feel any unpleasant symptoms after having an old shot of espresso, it’s best to see a doctor.
The Final Scoop on How Long Espresso Lasts
So, there you have it. You now know how long espresso is good for and how to store it properly.
The shelf life of espresso will vary depending on the freshness of the beans, the grind size, and the storage method. While you can safely store espresso in the refrigerator or freezer, unfortunately, it’s bound to lose some flavor with time.
Thankfully, you can try following our storage tips to preserve the freshness of espresso grinds, coffee beans or espresso shots for as long as possible.
Now that you know all about how to extend the lifetime of espresso, go forth and enjoy a heartwarming cup of coffee. But remember to avoid drinking old, cold espresso. It’s not worth the stale, bitter taste. And it’s definitely not worth diarrhea (or worse).
