Can You Heat Up Cold Brew Coffee?

Yes, you can actually reheat it if you need to although cold brew coffee is typically served cold. It’s made by steeping coffee grounds in cold water for an extended period of time, usually 12 hours or more. This results in a coffee that is less acidic and has a smoother flavour than coffee made with hot water. Thanks to its smooth, rich flavour, cold brew coffee is good for heating up and enjoying as a hot beverage. Just be careful not to overheat it, or you’ll end up with a bitter cup of coffee.

What Happens If You Heat Up Cold Brew Coffee?

If you heat up cold brew coffee, it will taste different than if you had brewed it hot and then cooled it down. The coffee would become bitter if you heated it up for a long period of time. For this reason, I recommend adding hot water to cold brew concentrate rather than heating up the coffee itself. Overall, heating up the coffee will cause the flavour to change slightly, but the good news is for most people, it will still be coffee.

How To Heat Up Cold Brew Coffee

If you’re a cold brew coffee fan, you know that one of the best things about it is that you can make it ahead of time and have it ready to drink when you want it. But what do you do when you want to enjoy a hot cup of cold brew? Here are a few easy ways to heat up your cold brew coffee so you can enjoy it any time of day.


One way is to put your cold brew coffee in a microwave-safe mug and heat it in the microwave in 30-second increments until it’s warmed to your liking.


Another way is to put your cold brew coffee in a saucepan on the stove over low heat until it reaches the desired temperature.

Boiled Water

You can also pour your cold brew concentrate and the equal part of boiling water into a mug and then stir them together.

As you can see now, heating up cold brew coffee is a simple process that will allow you to enjoy your coffee even on the coldest days.

Does Heating Up Cold Brew Coffee Make It Acidic?

When it comes to cold brew coffee, there are two schools of thought: those who like it cold and those who prefer it hot. But does heating up cold brew coffee make it acidic? Here’s what we know: cold brew coffee is made by steeping coffee beans in cold water for 12 hours or more. This process extracts the coffee’s natural flavours and oils, resulting in a coffee that is less acidic than coffee that is brewed with hot water. So, does heating up cold brew coffee make it acidic? No, not necessarily. It would be still less acidic compared to the coffee brewed with hot water. However, it may change the flavour of the coffee and make it less smooth.

How Long Does Cold Brew Coffee Last In The Fridge?

Cold brew coffee is a great option for those who want to enjoy a rich, flavourful cup of coffee without all the acidity. But how long does cold brew coffee last in the fridge? Generally, cold brew coffee will last in the fridge for up to two weeks. However, cold brew coffee can go bad if it’s not stored properly, just like any other food. Therefore, it’s best to consume it within the first week for the best flavour. After that, the coffee may start to lose its flavour. So, if you make a big batch on Sunday, you can enjoy it all week long. If you notice that your coffee is starting to taste sour or flat, it’s time to toss it out. To enjoy your cold brew coffee for as long as possible, be sure to store it in a sealed container to keep it fresh.

Can I Use Warm Water For Cold Brew?

If you’re looking to make cold brew coffee at home,  you may be wondering if you can use warm water. The answer is yes, warm water can be used for cold brew. But the results may not be ideal. Cold brew coffee is typically brewed with cold or room temperature water to extract a more mellow flavour. On the other hand, warm water can speed up the extraction process and produce a more bitter cup of coffee. If you choose to use warm water for cold brew, I highly recommend monitoring the brew time closely to avoid over-extraction.
