I have always been curious about the world of coffee, and as I embarked on my journey to explore its many aspects, I stumbled upon an intriguing question: Is a latte less acidic than coffee? This question piqued my interest, as I had always wondered about the pH levels of these two popular beverages. In this article, I will delve into the world of coffee and lattes, and explore the acidity levels they possess.
The World of Coffee and Lattes
What Makes Coffee Different from Lattes?
Before we delve into the topic of acidity, let’s understand the fundamental differences between coffee and lattes. Coffee, in its purest form, is made by steeping coffee grounds in hot water, resulting in a strong and bold beverage. On the other hand, a latte is a combination of espresso and steamed milk, topped with a layer of frothed milk. Lattes are known for their creamy and smooth texture, making them a popular choice for many coffee enthusiasts.
Understanding Acidity
To comprehend the concept of acidity, we need to delve into the world of pH levels. The pH scale ranges from 0 to 14, with 7 being neutral. Anything below 7 is considered acidic, while anything above 7 is categorized as alkaline or basic. The lower the pH level, the more acidic a substance is.

The Acidity of Coffee Beans
Coffee beans, the foundation of any coffee beverage, play a crucial role in determining the acidity of the final product. The two main types of coffee beans are Arabica and Robusta. Arabica beans are generally known for their lower acidity levels compared to Robusta beans. However, it’s important to note that the overall acidity of coffee is influenced by various factors, such as the brewing method, roast level, and water quality.
Factors Affecting the Acidity of Coffee
1. Roast Level:
– Darker roasts, such as French or Italian roasts, tend to have lower acidity than lighter roasts like City or Full City. The longer roasting process can reduce the perceived acidity in the coffee.
– Lighter roasts, on the other hand, preserve more of the natural acidity present in the coffee beans, resulting in a brighter and more acidic cup of coffee.
2. Brewing Method:
– The brewing method also plays a significant role in the acidity levels of coffee. Brewing methods that expose coffee grounds to hot water for a longer duration, such as French press or cold brew, tend to extract more acidity from the beans.
– On the contrary, brewing methods like pour-over or espresso typically result in a less acidic cup of coffee due to the shorter extraction time.
3. Water Quality:
– The quality of water used for brewing can affect the acidity of coffee. Water with a higher mineral content, such as hard water, can neutralize some of the acidity, resulting in a smoother taste.
– Conversely, using soft or filtered water may lead to a more noticeable acidity in the brewed coffee.
The Science Behind Latte’s Acidity
The Role of Milk in a Latte
When it comes to lattes, the acidity levels are influenced not only by the coffee but also by the addition of milk. Milk has a slightly alkaline pH, ranging from around 6.4 to 6.8. Therefore, when milk is mixed with coffee, it has the potential to neutralize some of the coffee’s acidity.
The Impact of Milk Frothing
The frothing process, which gives lattes their signature creamy and velvety texture, can also impact the acidity. During frothing, air is incorporated into the milk, which can increase its alkalinity. This can further contribute to lowering the overall acidity of the latte compared to a regular coffee.
Conclusion
In conclusion, the acidity of a latte can indeed be lower than that of a regular cup of coffee. The addition of milk, with its slightly alkaline pH, can neutralize some of the acidity present in the coffee. However, it’s important to note that the final acidity levels of both beverages can be influenced by various factors, such as the type of coffee beans, roast level, brewing method, and water quality.
Exploring the pH levels of coffee and lattes allowed me to gain a deeper understanding of the science behind these popular beverages. Whether you prefer a bold cup of coffee or a creamy latte, it’s fascinating to know how acidity plays a role in shaping the flavors we enjoy. So, the next time you sip your morning brew, take a moment to appreciate the delicate balance between acidity, aroma, and taste that makes each cup unique.
