Is Coffee Acidic? What is the PH of Coffee? Tips to Brew Balanced Coffee


Coffee is one of the most popular beverages worldwide, and while it is often associated with a quick boost of energy, many people wonder about its acidity levels. Is coffee acidic, and if so, what does that mean for your health? In this post, we’ll explore the world of coffee acidity, from its pH levels to the brewing methods that can affect it. We’ll also delve into some common concerns people have about the effects of coffee on the body, including inflammation and joint pain. So, let’s get brewing!

What is Coffee Acidity, and Why Does it Matter?

Coffee acidity refers to the pH levels in coffee, which can range from about 4 to 5 on the pH scale. The acidity of coffee is due to organic acids like chlorogenic acid, quinic acid, and citric acid, which are present in coffee beans. While coffee acidity doesn’t necessarily indicate the pH level of the drink, it can affect the flavor and taste of coffee.

The acidity of coffee matters because it can affect how your body processes the drink. For instance, if you suffer from acid reflux, drinking highly acidic coffee can exacerbate the issue. Additionally, some people find that high-acidic coffee can cause inflammation and joint pain. On the other hand, some coffee lovers enjoy the fruity and bright flavors that come from higher acidity levels.

What Makes Coffee Acidic?

Several factors contribute to the acidity of coffee. First and foremost, the type of coffee bean plays a crucial role. Arabica beans tend to have a higher acidity level than Robusta beans, which have a milder flavor. The roasting process also plays a role, with lighter roasts having higher acidity levels than darker roasts. The brewing method can also affect acidity, with hot water methods like drip coffee and French press producing more acidic coffee than cold brew methods.

How Can You Make Coffee Less Acidic?

If you love coffee but suffer from acid reflux or joint pain, there are several ways to reduce the acidity of your brew. Here are some tips:

  1. Use low-acid coffee beans. Some coffee brands offer low-acid varieties that are gentler on the stomach.
  2. Try cold brew coffee. Cold brew methods produce coffee with lower acidity levels than hot water methods.
  3. Add a pinch of baking soda. Baking soda can neutralize the acidity of coffee and make it easier on your stomach.
  4. Use a coffee maker with a paper filter. Paper filters can remove some of the acid-causing compounds in coffee.

Different Brewing Methods

As mentioned earlier, the brewing method can affect the acidity of coffee. Here are some of the most popular brewing methods and how they impact acidity:

  1. Drip coffee: This method uses hot water to brew coffee through a paper filter, which removes some of the acidic compounds. However, drip coffee can still be quite acidic.
  2. French press: French press coffee has a higher acidity level because it uses a metal filter that doesn’t remove as many acidic compounds.
  3. Cold brew: Cold brew methods produce coffee with lower acidity levels than hot water methods, making it a great option for those with acid reflux or sensitive stomachs.

Ways to Reduce Acidity

Besides changing your brewing method or using low-acid beans, there are several other ways to reduce the acidity of your coffee. Here are some options to try:

  1. Add milk or cream. The fat in milk and cream can help neutralize the acidity of coffee.
  2. Try soy milk. Soy milk has a higher pH level than regular milk, making it a great option for those with acid reflux.
  3. Drink water after coffee. Drinking water after coffee can help neutralize the acid in your stomach.Does coffee cause inflammation?Inflammation is a natural process that happens in our bodies as a response to injury or infection. It helps to heal the damaged tissue and fight off infection. However, chronic inflammation can be harmful and has been linked to many diseases, such as cancer, diabetes, and heart disease.

    There is some evidence that suggests that drinking coffee may cause inflammation in the body. A study published in the American Journal of Clinical Nutrition found that consuming caffeinated coffee can increase the levels of C-reactive protein (CRP) in the blood. CRP is a marker of inflammation and has been associated with an increased risk of heart disease and other chronic diseases.

    However, it’s important to note that other studies have shown conflicting results. For example, a study published in the Journal of the American College of Cardiology found that moderate coffee consumption was not associated with an increased risk of cardiovascular disease.

    Overall, the evidence regarding coffee and inflammation is mixed. While some studies suggest that coffee can cause inflammation, others show no association or even suggest a protective effect.

    Can coffee make your joints hurt?

    Joint pain is a common problem that affects many people, especially as they age. There are many factors that can contribute to joint pain, including injury, arthritis, and inflammation.

    Some people believe that drinking coffee can worsen joint pain. The reasoning behind this belief is that coffee contains caffeine, which is a stimulant that can increase the levels of cortisol in the body. Cortisol is a hormone that is involved in the body’s stress response and can cause inflammation.

    However, the evidence linking coffee consumption to joint pain is mixed. Some studies have found that coffee may have anti-inflammatory effects and may actually be beneficial for joint health. For example, a study published in the Annals of the Rheumatic Diseases found that drinking coffee was associated with a lower risk of developing rheumatoid arthritis.

    Other studies have found conflicting results. For example, a study published in the journal Osteoarthritis and Cartilage found that coffee consumption was associated with an increased risk of developing osteoarthritis.

    Overall, the evidence regarding coffee and joint pain is mixed. While some studies suggest that coffee may worsen joint pain, others show no association or even suggest a protective effect. If you experience joint pain, it’s important to speak with your healthcare provider to determine the underlying cause and develop an appropriate treatment plan.

    Alternatives to Coffee

    If you’re looking to cut back on coffee or switch to a lower-acid alternative, there are many options to choose from:

    1. Herbal tea: Herbal teas are a great alternative to coffee, and they come in a wide variety of flavors. They are also caffeine-free, which means they won’t cause the jitters or anxiety that coffee can cause.  Check out Sip Herbals Signature Roast Herbal Coffee.
    2. Decaffeinated coffee: If you love the taste of coffee but want to reduce your caffeine intake, decaffeinated coffee is a good option. Just make sure to check the label to ensure that it is a low-acid blend.
    3. Green tea: Green tea has many health benefits, including reducing inflammation and boosting brain function. It also has a lower caffeine content than coffee.
    4. Golden milk: Golden milk is a popular drink made from turmeric, ginger, and coconut milk. It is a great option for those looking to reduce inflammation and boost their immune system.


    In conclusion, coffee is acidic, but the degree of acidity varies depending on the brewing method, roast, and bean type. While some people may experience discomfort or acid reflux after drinking coffee, others may not have any adverse effects. If you want to reduce the acidity of your coffee, there are several methods you can try, such as using low-acid beans, cold brewing, or adding milk. And if you’re looking for a lower-acid alternative to coffee, there are many options to choose from, such as herbal teas, decaffeinated coffee, green tea, and golden milk. By experimenting with different brewing methods and trying new drinks, you can find the perfect cup of coffee or alternative that works for you.
