How Long Is Brewed Coffee Good For At Room Temperature?

Let’s start this question at the very beginning and address freshly roasted coffee beans. Fresh coffee beans start to go off two weeks after roasting. Peak freshness for roasted coffee is 48 to 72 hours after roasting and for about 7 to 10 days after. I usually only keep my beans for 10 days after roasting. That is the benefit of getting in on the home roasting revolution, I roast my own beans once a week and enjoy maximum freshness.

Your freshly brewed cup of coffee will start to lose its freshness after about half an hour as the flavor compounds start to degrade. It will take about 4 hours for coffee oils to start to go off at this point you have lost that nice coffee flavor that you enjoyed hours ago.

If you want your coffee fresh drink it in the first 30 minutes and don’t let your coffee spoil!

Does Brewed Coffee Need To Be Refrigerated?

If you keep your brewed cup of coffee refrigerated, you will be able to maintain the taste of your coffee and the aromas better. You must store it well in a storage container with a lid. An airtight container with a lid is much better as coffee is great at absorbing flavors and aromas. If you leave it in an open mug, it will absorb the scents and flavors from the surrounding foods.

When you re-heat your cup of coffee it will not be as good as or as fresh as it was when you freshly brewed it.

While it is not an absolute must that you refrigerate your brewed pot of coffee, but if you do, you will have a better chance at maintaining flavor and aromas for longer.

How Long Is Brewed Coffee Good For In The Fridge?

Unfortunately, there are very few scientific studies to demonstrate the shelf life of a freshly brewed Cuppa Joe. What is contained here is based on my own experience and a few tests that I have run myself to find out.

Keeping your coffee in an airtight container in your fridge can help to keep a degree of its taste for around 2 days. It will have lost most of its freshness, but it will still taste good to okay.

Coffee with milk or dairy milk alternatives will reduce its storage time in your fridge to 2 days at most. This is the same for cow’s milk or almond milk coffee or coffee creamer. Adding milk reduces  the time in which you can enjoy it fresh at an ambient room temperature from 4 hours to 2 hours.

If you are adding any kind of milk to your coffee and storing it for a couple of hours or a couple of days, give it a sniff test and short taste test and check for signs of mold before you take any large gulps.

In fact, do that even for black coffee. You are better safer than sorry.

Why Does Your Coffee Taste Stale After It Has Been Sitting Out For A While?

Your coffee starts to taste stale after it is sitting out for a while is because the oxidization process does not stop once you have brewed your coffee. The reaction between the hydrogen and the oxygen increases the pH level of your coffee, which in turn makes it taste a little state or bitter.

This is why you should drink your coffee within 30 mins of it being brewed.

Other reasons for your coffee tasting off too quickly is due to over extraction, which can be caused by using the wrong grind size or too long a brew time.

This is exactly why you should never store your coffee in your French press and always decant when you’re using this brewing technique because your grounds will continue to extract while they are sitting in your French press.

How To Make Day Old Coffee Taste Good

By far the best way of making your day old coffee tasting good is to put to it in a pot and reheat it slowly and on a low heat. Heating too quickly or in the microwave does not work as well and destroys any aromatic compounds that my still be in your brew.

Slowly and patiently is the key here and don’t try or even think of accelerating the process.

  • 4. Frappé it up and make a frappé with it.

  • 6. Make coffee flavored ice cream!
  • 7. Marinade your meat and have a great coffee steak or burger.
  • 8. Boost up your morning coffee by giving it some competition and add it to your oatmeal for a very nice taste.

Can You Get Sick From Drinking Old Coffee?

It is safe to drink expired coffee as coffee doesn’t god at all that day. If you leave it long enough both out in the open on your counter top or in the fridge, it can start to go off and grow mold and taste very off which has the potential of making you sick with an upset stomach.

In most cases, that is all you will experience, but things can get serious due to the mold and how bad it can get.

Frappé-Ing It All Up – How Long Can Brewed Coffee Sit Out?

Your brewed coffee can sit out for about 30 mins before you have lost a good portion of the freshness, taste and aromas. You can leave black coffee at an ambient room temperature for about 4 hours before it becomes completely stale. Add milk and you can half the time.

The same formula applies if you are storing your coffee in the refrigerator – it will stay well for about 3 days as a black coffee and no more than 2 days if it is a coffee with milk.

Coffee is love, it's more than love — it's a passion of mine. I've had the luck to have travelled and enjoyed the most exotic of coffee's and unique flavors, brewing methods and techniques of making the perfect coffee from Thai hill tribe coffee to Indonesian volcanic coffee, Malaysian coffee that comes in a tea bag and the array of flavors in Vietnam, from Vanilla to Orange to Coconut to Avocado to even salt coffee and the famous egg coffee. The best part of my coffee adventures is getting to mix with the locals over a nice brew and learning how they make it! I'm cited and referenced on Google Scholar for the topic of coffee.
