A question that frequently arises is whether one of the most popular beverages is alkaline or not. 

To answer this, it’s essential to delve into the science of coffee’s acidity and pH levels.

Firstly, it’s important to realize that coffee acidity is dependent on various factors. Such as the coffee beans’ origin, brewing method, roast style, and more. 

Typically, coffee is considered to be one of the acidic foods, with a pH value ranging from 4.85 to 5.10.

It has less acidity than orange juice but slightly higher acidity than dairy milk, green tea, and tap water. 

On the other hand, alkaline coffee does exist, and it boasts a different set of benefits and potential drawbacks compared to traditional coffee.

Understanding Acidity and Alkalinity

pH Scale and pH Value

The pH scale is a logarithmic measure used to rank solutions in terms of acidity or basicity (alkalinity). 

The scale ranges from 0 to 14, where values below 7.0 are considered acidic. Values above 7.0 are considered alkaline or basic. 

For reference, pure water has a pH of 7.0.

  • pH 0: Highly acidic
  • pH 7: Neutral
  • pH 14: Highly alkaline/basic

Acids and Bases Present in Coffee

Coffee is known to be acidic, with a pH value of around 4.7 to 5. 

It contains several different acids which are known for making your morning coffee acidic.

Such as chlorogenic acid, acetic acid, phosphoric acid, lactic acid, and citric acid (one of the organic acids).

However, the good news is that the perceived acidity in coffee by your taste buds can vary depending on the type of bean used, brewing methods, and other factors. 

For example, for a more acidic cup of coffee, Robusta beans are used. 

To balance the acidity in coffee and monitor the body’s ph levels, some people add milk or other alkaline foods or substances. 

Adding milk can neutralize some of the acidity in coffee, thanks to the calcium present in it.

There are also various methods to control the acid levels in coffee. 

One such method is slow-steeping, which involves slowly introducing water into the coffee grounds over an extended period, sometimes up to 24 hours. 

The slow-steeping method helps extract more flavor from the coffee while reducing bitterness and acidity levels.

Coffee is considered acidic due to its pH value and the presence of acidic substances. But there are ways to adjust its acidity or alkalinity to suit individual preferences.
