Can You Heat Up Cold Brew Coffee? The Quick Answer

Many coffee lovers often wonder if you can heat up cold brew coffee. And the answer? Of course you can!

There are many ways to do this, from microwaving your cold brew to heating it up on a stovetop, of which we will go into more detail below.

What’s the Difference Between Cold Brew and Regular Coffee?

First, let’s take a quick look at what cold brew coffee is and how it’s different from regular coffee.

Cold brew coffee is made by steeping coffee grounds in cold water for an extended period of time, typically between 12 and 24 hours.

This creates a smooth, rich, and full-bodied coffee that is less acidic and less bitter than regular coffee. 

It’s a great option for coffee lovers who want a delicious and refreshing drink without the bitterness of regular coffee.

Should You Heat Up Cold Brew Coffee?

If you speak to any so-called coffee ‘experts,’ they will tell you that cold brew coffee should always be served cold. But what do they know? When it’s heated up perfectly, it’s one of the best coffee tastes you can experience.  

The Different Ways You Can Heat Up Cold Brew Coffee

Here are a few different ways you can heat up cold brew coffee:


The quickest and easiest way to heat up cold brew coffee is to use the microwave.

Simply pour your cold brew into a microwave-safe mug or cup and microwave it for 30-60 seconds, or until it reaches your desired temperature.

Just be careful not to overheat your cold brew, as this can affect its flavor and make it taste burnt or bitter.


Another way to heat up cold brew coffee is to use the stovetop. This is the best way to het up cold brew coffee.

Simply pour your cold brew into a saucepan and heat it over medium-low heat until it reaches your desired temperature. 

This method allows you to control the temperature more precisely and avoid overheating your cold brew.

Just Add Hot Water

You will find that a lot of cold brew you buy is concentrated. This means that you need to add your own water.

Because of this, you can just heat up the water, pour it onto the cold brew concentrate, and you’ll have yourself a hot cold brew in no time!

This is by and large the best method, mainly due to the fact that there’s no chance the coffee can be burnt, unlike the other options. 

Does Heating Cold Brew Coffee Make It Acidic?

Cold brew coffee has gained popularity for its smooth and less acidic flavor compared to traditional hot brewed coffee. 

Many people often wonder: does heating cold brew coffee make it acidic? Let’s delve into the topic and explore the effects of heating on the acidity of cold brew coffee.

This slow extraction process results in a different flavor profile compared to hot brewed coffee. Cold brew coffee is known for its smoothness, lower bitterness, and reduced acidity.

Heating cold brew coffee may affect its acidity to some extent, but the overall impact depends on various factors. When you heat cold brew coffee, chemical reactions occur which can alter its taste and composition. 

One of these reactions is the breakdown of certain compounds present in coffee, including acids.

During the heating process, acids naturally present in coffee may undergo further decomposition. This can lead to a slight increase in acidity compared to the original cold brew coffee. 

However, it’s important to note that the increase in acidity is typically minimal and might not be noticeable to most individuals.

Factors Influencing Acidity Changes

Several factors play a role in determining the extent of acidity changes when heating cold brew coffee:

Brewing Method: The specific brewing method used for cold brew coffee can affect its chemical composition. Different techniques and brewing ratios may result in varying levels of acidity.

Coffee Beans: The type and quality of coffee beans can impact the acidity of cold brew and heated coffee. Different coffee varieties have varying levels of acidity naturally.

Brew Time: The duration of steeping during cold brew preparation can affect the extraction of acids. Longer brewing times may result in a higher concentration of acids in the cold brew coffee.

Heating Temperature: The temperature at which cold brew coffee is heated can influence the extent of acidity changes. Higher temperatures might lead to more significant alterations in acidity.

Heating cold brew coffee may cause a slight increase in acidity, but the change is generally minimal and might not be discernible to most individuals. 

Can You Heat Up Cold Brew Coffee Overnight?

The short answer is yes, you can heat up cold brew coffee, but it may alter the taste and overall experience. When you heat cold brew, you essentially transform it into hot coffee, which can lead to flavor changes and the loss of some characteristics that make cold brew unique.

Heating cold brew coffee can result in a loss of the smooth and subtle flavors that cold brewing imparts. 

The extended steeping process of cold brew extracts different compounds from the coffee beans compared to hot brewing methods. 

Reheating cold brew may accentuate bitterness and acidity while diminishing the natural sweetness and delicate flavor notes.

Can I Warm Up My Starbucks Cold Brew?

Starbucks cold brew is a refreshing and energizing beverage, perfect for hot summer days or whenever you’re in need of a caffeine boost. 

But what if you find yourself with a cold cup of Starbucks cold brew that you’d prefer to enjoy warm instead? Can you warm it up?

Unfortunately, Starbucks’ cold brew is specifically designed to be enjoyed cold. The brewing process and concentration of flavors are optimized for a chilled drinking experience. 

Attempting to warm up your cold brew may alter the taste and compromise the quality of the beverage. Additionally, heating cold brew can result in a loss of some of the desirable flavors and aromas that make it unique.

Is Cold Brew Hard On the Stomach?

Cold brew coffee has gained popularity in recent years due to its smooth and less acidic taste compared to traditional hot brewed coffee. 

While it offers a refreshing alternative for coffee lovers, some individuals may wonder if cold brew is hard on the stomach. 

One of the primary reasons why cold brew is perceived to be less harsh on the stomach is its reduced acidity. 

The acids present in coffee, such as chlorogenic acid and quinic acid, can stimulate acid production in the stomach, potentially leading to acid reflux, heartburn, or stomach discomfort. 

Cold brew’s lower acidity may make it a more tolerable option for individuals who are sensitive to highly acidic beverages.

Cold brew’s smoother flavor profile and reduced acidity may be advantageous for individuals with sensitive stomachs or those who experience gastrointestinal issues after consuming regular coffee. 

However, it’s important to note that individual reactions to coffee can vary. 

Some individuals may still experience stomach discomfort or digestive issues even with cold brew coffee, albeit to a lesser extent.

While cold brew may have a milder impact on the stomach due to reduced acidity, it still contains caffeine, which can affect some individuals. 

Caffeine is a natural stimulant that can stimulate gastric acid production and increase bowel movement frequency. 

People who are more sensitive to caffeine may experience stomach irritation, jitters, or an upset stomach, regardless of whether the coffee is hot or cold brewed.

Consider Drinking In Moderation

It’s crucial to consider personal sensitivities and moderation when consuming cold brew or any other caffeinated beverage. 

Some individuals may have specific sensitivities to coffee compounds or may be more prone to stomach issues in general. It’s recommended to pay attention to your body’s response and adjust your coffee consumption accordingly. 

Gradually introducing cold brew into your routine and monitoring its effects can help you determine if it’s well-tolerated by your stomach.

Is Cold Brew the Healthiest Coffee?

Coffee is a beloved beverage enjoyed by millions around the world. In recent years, cold brew coffee has gained significant popularity due to its unique brewing method and smooth flavor. 

But is cold brew really the healthiest coffee option?

Coffee is a significant source of antioxidants, which play a vital role in protecting our bodies against harmful free radicals. Cold brew coffee retains a substantial amount of antioxidants during the brewing process, just like its hot-brewed counterpart. 

These antioxidants have been linked to various health benefits, including a reduced risk of chronic diseases such as heart disease, certain cancers, and neurodegenerative disorders.

Wrapping Up

No matter which method you choose, it’s important to remember that heating up cold brew coffee will change its flavor and texture slightly. 

Cold brew is best enjoyed cold, so if you’re looking for a warm cup of coffee, it’s probably best to stick with regular brewed coffee.

However, if you’re feeling adventurous and want to try something different, heating up cold brew coffee can be a fun and tasty way to enjoy your favorite drink in a new way. 

Just be sure to experiment with different temperatures and heating methods to find the one that works best for you.
