Is Instant Coffee Less Acidic Than Brewed?

I have always been a big fan of coffee, and the world of coffee is a vast and fascinating one. Recently, I came across a debate that caught my attention – is instant coffee less acidic than brewed coffee? As someone who is conscious of the potential effects of acidity on my stomach, I decided to delve into this topic and find out the truth behind this claim. In this article, I will explore the factors that contribute to the acidity of coffee, compare the acidity levels of instant and brewed coffee, and provide some tips on how to reduce the acidity in your coffee for a more enjoyable drinking experience.

Understanding Acidity in Coffee

To properly grasp the concept of acidity in coffee, we need to take a step back and understand some basic chemistry. Acidity refers to the presence of acids in a substance measured on the pH scale, which ranges from 0 to 14. A pH value of 7 is considered neutral, while values below 7 indicate acidity and values above 7 indicate alkalinity. In the case of coffee, acidity contributes to its flavor profile, providing bright and vibrant notes that differentiate between different coffee origins and roasts.

Factors Affecting Coffee Acidity

Several factors influence the acidity of coffee, including the type of coffee bean, the roast level, and brewing methods. Different coffee beans have varying levels of acidity inherent to their genetic makeup. For example, beans from Central America are often known for their bright and citrusy acidity, while beans from Asia tend to have a lower acidity with more earthy and chocolaty flavors.

Furthermore, the level of roasting also plays a significant role in the acidity of coffee. Lighter roasts tend to be more acidic as the beans are roasted for a shorter duration, allowing the natural acidity to be more prominent. On the other hand, darker roasts are roasted for a longer time, resulting in a reduced acidity and a more bitter and robust flavor profile.

Finally, brewing methods also impact the final acidity of the coffee. Methods like cold brewing, which involves steeping coffee grounds in cold water for an extended period, typically yield a less acidic cup of coffee compared to hot brewing methods like pour-over or espresso.

Comparing Instant Coffee and Brewed Coffee

Now that we have a better understanding of the factors that contribute to coffee acidity, let’s compare the acidity levels of instant coffee and brewed coffee. Instant coffee is made by freeze-drying or spray-drying brewed coffee, resulting in a soluble form that dissolves quickly in hot water. This manufacturing process can affect the overall acidity of the coffee.

Instant Coffee and Acidity

Instant coffee is often considered less acidic than brewed coffee due to the manufacturing process. The extraction of the coffee compounds during brewing can contribute to increased acidity in the final cup. However, during the production of instant coffee, some of these compounds are lost, resulting in a reduced acidity level. Additionally, the soluble nature of instant coffee allows it to bypass the stomach’s acid-producing cells, leading to a potentially less acid-induced stomach response.

Brewed Coffee and Acidity

On the other hand, brewed coffee can vary in acidity depending on the factors mentioned earlier. Lighter roasts and certain coffee origins tend to yield a more acidic cup of coffee. Brewing methods that involve higher water temperatures, like espresso, can also extract more acidity from the coffee grounds.

Reducing Acidity in Coffee

If you’re concerned about the acidity of your coffee and its potential effects on your stomach, there are a few ways you can reduce the acidity for a more gentle coffee experience.

Choose Low Acid Coffee Beans

Selecting coffee beans with naturally lower acidity levels can significantly impact the overall acidity of your cup of coffee. Beans from regions like Brazil, Sumatra, or even decaffeinated coffee tend to have lower acidity, making them great choices for those seeking a less acidic alternative.

Opt for Darker Roasts

Darker roasts can also be a viable option for those looking to reduce acidity. The extended roasting time helps to break down some of the acids present in the coffee beans, resulting in a smoother and less acidic cup.

Try Cold Brew

Cold brewing is an excellent method for producing a less acidic cup of coffee. By steeping coffee grounds in cold water for an extended period (usually overnight), the resulting brew contains less acidity and bitterness. Furthermore, the slow extraction process in cold brewing can emphasize the coffee’s natural sweetness and flavors.


In conclusion, the acidity of coffee is a complex subject influenced by various factors, including the type of coffee bean, roast level, and brewing method. While instant coffee is generally considered less acidic than brewed coffee due to the manufacturing process, it is essential to consider other factors that contribute to coffee acidity. Ultimately, personal taste preferences and acidity tolerance will determine which coffee option is best for you. Experimenting with different coffee origins, roasts, and brewing methods can help you find the perfect cup of coffee that suits your palate and stomach. Cheers to a flavorful and enjoyable coffee-drinking experience!
