For some of us, coffee is essential to our morning routines and doing work. And although you might love the taste, did you know that a cup of java can actually affect your body beyond giving you a boost? Specifically, is coffee an acid?

In this blog post, we’ll be exploring all the questions surrounding how acidic or alkaline your favorite brew really is before going into detail about potential health benefits or risks associated with consuming coffee. So whether you’re firmly rooted in the “coffee camp” or just curious about this ever-popular drink, read on to learn more!

Is Coffee An Acid?

Acidity In Coffee
Coffee Is An Acid As Its pH Is Lower Than 7

In short, coffee is acidic. This means that it has a pH level lower than 7 1, which is from 4.58 to 5.13 according to NLM 2 , and it can impact your body’s pH balance. However, this doesn’t mean that drinking coffee is bad for your health; in fact, there are several potential benefits associated with consuming coffee.

Coffee contains compounds such as caffeine and chlorogenic acids, antioxidants that protect against oxidative damage. Additionally, coffee consumption reduces the risk of certain health conditions like type 2 diabetes, heart disease, Alzheimer’s disease, and cancer.

It is also important to note that although coffee can be acidic, the overall pH level of your body is regulated by several other factors, such as diet and lifestyle. So while it’s true that drinking an excess amount of coffee could potentially affect your pH balance, adopting healthier habits like exercising regularly and eating a balanced diet are just as important when it comes to managing your body’s acidity levels.

What Are The Factor That Make Acidity In Coffee?

Types Of Beans

Acidity In Coffee Beans
Robusta Tends To Have Higher Acidity Than Others

The type of beans used to make coffee can significantly impact the acidity level of your favorite brew. For instance, Robusta beans, known for their bold flavor and higher caffeine content, tend to exhibit a noticeably higher acidity level than their Arabica counterparts. This is primarily attributed to the higher concentration of chlorogenic acids present in Robusta beans, which contribute to their distinct taste profile.

On the other hand, Arabica beans, prized for their smoothness and nuanced flavors, generally have a milder acidity due to their lower chlorogenic acid content. So, the coffee bean choice affects the taste and acidity level, giving coffee enthusiasts a wide range of options to explore and enjoy.


The roasting process is another factor that can profoundly impact the acidity level of your coffee. The darker roast has the least acidity, while the lighter roasts are more acidic. This is because some of their natural oils and acids are cooked off when coffee beans are roasted, resulting in a less acidic brew. On the other hand, light-roasted beans retain much of their original flavor characteristics, making them slightly more acidic.

Brewing Method

The way you choose to brew your coffee can have a significant impact on its overall acidity level. For example, when it comes to espresso, its high-pressure extraction process tends to result in a more acidic taste compared to other brewing methods. On the other hand, cold brew coffee is well-known for its smooth and mellow flavor, partly because the grounds are steeped in cold water for an extended period, resulting in lower acidity levels.


The freshness of your coffee beans can play a major role in determining acidity levels. Older beans that have been exposed to air for longer periods tend to lose their flavor and aroma, leading to an overall decrease in their acidity level.

On the other hand, freshly roasted coffee beans retain more of their acidic properties due to their high moisture content. This makes them more acidic and allows their natural flavors to shine through in your final cup of coffee.


The grind size of your coffee not only its taste but also its acidity level. Using a finer grind increases the surface area of the coffee particles, facilitating a faster extraction process. This quick extraction increases acidity levels, giving your coffee a bright and vibrant taste. Conversely, a coarser grind slows the extraction process, allowing for a smoother and less acidic cup of coffee. By adjusting the grind size, you can fine-tune the acidity level of your brew to suit your preferences.

How To Balance The Acidity Of Coffee

If you’re concerned about the acidity of your coffee, there are a few ways to balance it out. The easiest way is to add milk or cream, as these dairy products can neutralize the acids in coffee and give it a more balanced taste. Alternatively, you could also try adding some other natural ingredients like cinnamon or honey, which can help balance out the flavor of your brew without making it too sweet.

Another easy way to reduce the acidity of your coffee is to use cold-brewed coffee. Cold brewing involves steeping grounds in cold water for an extended period, which can help create a less acidic and smoother tasting cup of joe. According to Scientific Report 3, cold-brewed coffee has a lower acidity and is less likely to cause any digestive distress than hot brewed coffee.

What Are The Benefits And Drawbacks Of Acidity In Coffee?


The acidity of coffee is one of its main benefits. Coffee is known for its energizing effect, largely due to caffeine being released into your bloodstream when you consume it. The coffee’s acidic content helps boost the caffeine’s effects, so you can get a more intense energy boost from your cup of joe.

Also, the acidity of coffee helps to bring out its flavor, giving it a more robust and complex taste. Coffee is one of the few beverages that can contain hundreds of different aroma compounds, which are made more recognizable thanks to the acidic content in coffee beans. To our health, the acidity of coffee can also be beneficial as some studies suggest 4 that it might reduce your risk of type 2 diabetes, heart disease, and certain kinds of cancer.


The high acidity of coffee can also be its downfall. Too much acidic content in your body, including coffee consumption, can lead to issues like stomach upset or heartburn. In addition, the acids in coffee can erode tooth enamel over time, so it’s important to keep an eye on how much coffee you drink and to brush your teeth regularly.

Another issue can arise when coffee is brewed too hot or too long. This can extract more acids from the grounds, resulting in a cup of coffee that’s too bitter or sour for many people’s tastes. This is why it is important to ensure that you are using the right coffee-to-water ratio and brewing for the correct amount of time.


To sum up, is coffee an acid? Yes, coffee is acidic; the acidity levels can vary depending on how it was brewed, but generally, moderate to high amounts are found in every cup. While there are some benefits to consuming coffee with this level of acidity – like increased energy and improved flavor – it is important to be mindful of how much coffee you are drinking to avoid any health risks. With the right blend and brewing techniques, however, you can enjoy a great cup of coffee that’s full of flavor without worrying about its acidity levels.


Is Coffee Acidic Or Basic?

Coffee is acidic, with an average pH of around 5. It can range from 4.5-6 depending on the brewing process and type of beans used.

What Does Acidity in Coffee Taste Like?

The acidity in coffee can give it a pleasant flavor that contributes to its overall taste profile. When brewed correctly, the acidity should not be overpowering and can result in a smoother cup of coffee.

Is Acid In Coffee Highest Compared To Other Drink?

Coffee is generally one of the most acidic drinks, with a pH between 4.5-6. This is higher than other caffeinated beverages like green or black tea, which fall closer to neutral on the PH scale. Other non-caffeinated beverages, such as orange juice, are more acidic than coffee but still less so than sodas and energy drinks.

How Can You Reduce Acidity in My Coffee?

There are a few ways to reduce the acidity of your coffee, such as using a cold brew or a longer extraction time for espresso. You can also purchase specialty beans specifically designed to be low-acid, though these tend to be more expensive.
