Espresso and regular coffee differ in their acidity levels, as espresso is less acidic due to the dark roast beans and the brewing process. Regular coffee, on the other hand, can be more acidic due to beans’ type and roast levels.
If you have sensitive stomachs or acid reflux issues, drinking espresso or a darker roast coffee may be a better option. But ultimately, it comes down to personal preference, and you should experiment with different coffee types and roasting levels to find your ideal taste and acidity level.
Espresso, known for its concentrated flavor and smooth texture, is different from regular coffee, which is typically brewed. One of the factors that set these two coffee types apart is acidity.
Acidic drinks can cause gastrointestinal discomfort or acid reflux, making it crucial to know which coffee is low in acidity. This blog post will explore the acidity levels of both espresso and regular coffee and comparing their pH values.
Why is Espresso Less Acidic and More Bitter Than Coffee?
Acidity levels are an essential aspect of coffee flavors and have a significant impact on the overall coffee drinking experience. Espresso is less acidic and more bitter than coffee, due to the roasting process, and brewing method.
There are a variety of different roasts and brewing methods for espresso, so it’s always a good idea to experiment and find what tastes best for you.
To fully understand why espresso has less acidity and more bitterness than coffee, it is critical to first understand the chemistry behind their taste profiles. A key factor in acidity and bitterness is the presence of chlorogenic acids in coffee and roasting process.
These acids are present in green coffee beans and are released during the roasting process. The longer the roasting time, the more chlorogenic acids break down, which ultimately leads to lower acidity and more bitterness. The extraction of bitter chemicals during the brewing process is also different in espresso and coffee, because of the brewing process. The second factor that impacts the taste difference between espresso and coffee is the roasting process. Coffee beans and espresso beans undergo a similar roasting process, whereby the initial green beans are heated to high temperatures until they reach their desired roast level.
The Maillard reaction is the key here and it is what gives espresso its unique flavor profile. This reaction occurs between the sugars and amino acids in the beans, resulting in the development of complex flavors and aromas. As the beans are roasted, they become less acidic and more bitter, leading to a smoother taste in espresso.

Impact of Darker Roasts on Espresso Acidity
The process of coffee roasting is a chemical reaction that involves breaking down organic acids naturally present in coffee beans. During roasting, these acids are burned off resulting in a reduction of acidity in the coffee. The longer the roasting time, the more organic acids are lost, resulting in less acidic taste. This is why darker roasts are generally less acidic than lighter roasts.
Darker roasts are roasted for a longer period, resulting in a sweeter, smokier, and less acidic flavor profile. Research indicates that the longer roasting time causes the coffee beans to lose some of their acidity, thereby reducing the overall acidity levels.
However, using dark roast can also mask the quality of the coffee beans and make it difficult to distinguish between different coffee bean varieties.
The darkness of the roast is also important in determining the acidity and bitterness of the coffee or espresso. The variation in roast level explains why some espresso has more bitterness than others, depending on how much coffee was in the blend.
Light to medium roast coffees are known for their high levels of bright acidity, with flavors reminiscent of fruit and florals. Dark and espresso roasts, on the other hand, are known for their deep, rich flavors, with lower levels of acidity.
This is why some people prefer the boldness of dark roast coffee while others prefer the brighter flavors of light and medium roasts.
Misconceptions About Acidity and Bitterness in Espresso
Espresso can sometimes taste bitter, acidic, or both at the same time, which can lead to confusion between these two components. One common misconception is that espresso is bitter, when the high concentration of coffee solids actually makes it more acidic than it appears.
On the other hand, low acidity can be mistaken for bitterness, which adds a less sweet taste to the coffee. Distinguishing between these two components is crucial to understanding the coffee’s taste profile.
Understanding the difference between acidity and bitterness in espresso is key to appreciating its taste profile. Acidity adds brightness and complexity, while bitterness adds depth and intensity.
Experimenting with different brewing methods and coffee selections can help you find your preferred taste profile. Don’t hesitate to ask your barista for advice and share your preferences to get the ideal cup of espresso.
Acidity in Espresso
Espresso acidity is a crucial element of a well-crafted shot. It defines the brightness, fruity, or tangy flavor that gives the espresso the perfect balance. The acidity level can transform the aroma from a hint of floral to nutty and chocolate. It enhances the drink’s mouthfeel and helps to bring out all the notes present in the coffee beans.
Bitterness in Espresso
Bitterness is a taste sensation that is perceived at the back of the tongue, characterized by a harsh and unsavory flavor. In espresso, bitterness is often more prominent compared to other coffee types due to the brewing method, which extracts more compounds from the coffee beans.
The degree of bitterness in espresso can depend on the brewing temperature, grind, and extraction time. Lower temperatures and coarser grinds produce less bitterness, while higher temperatures and finer grinds increase bitterness. Over-extracting espresso can also contribute to bitterness, so it’s crucial to use the right amount of coffee and extraction time.
How to Evaluate Acidity and Bitterness in Espresso
Developing your taste sensitivity and preferences is the first step to evaluating acidity and bitterness in espresso. There are several techniques for evaluating their levels accurately, such as cupping, tasting, and measuring pH levels. Adjusting the brewing process, such as the grind size or water temperature, can help achieve the desired level of acidity or bitterness.
Famous Origins of Espresso Low-Acid Coffees:
Brazil, Sumatra, and Nicaragua are all countries known to produce low-acid coffee. The climate and altitude conditions in these countries contribute to the production of beans with naturally low acidity levels.
- In Brazil, the use of Arabica beans grown at a lower altitude and wet-processed results in a sweeter and smoother taste profile, with lower acidity.
- Sumatra has beans grown at higher altitudes, which results in a lower acidity profile and a bold, earthy flavour.
- Nicaragua is famous for its Arabica beans and dry-processing method, which produces coffee with a low-acid profile but with a mild-medium body.
Understanding Espresso Acidity – Why pH Level Doesn’t Matter
While many coffee enthusiasts measure acidity based on pH level, there is a common misconception that pH level is the only indicator of acidity in coffee. Ot’s essential to understand that pH level is not the main indicator of acidity in coffee.
pH level only measures the concentration of hydrogen ions and does not directly measure acidity in coffee. Coffees with different pH levels can have similar levels of acidity. For example, Sumatra and Kenya both have different pH levels but similar acidity.
Comparing coffee pH levels to other popular beverages such as apple juice and milk, it’s evident that pH levels do not necessarily correspond to taste perception. For example, coffee has a lower pH level than apple juice, yet coffee tastes more acidic due to the higher concentration of the organic acids we mentioned.
Factors Affecting Acidity in Espresso
Several factors affect the acidity level of Espresso coffee beans. Altitude, climate, coffee variety, and processing methods can all influence the level of acidity in coffee beans. Roasting can also modify acidity levels. For example, lighter roasts tend to have more acidity, while darker roasts have less acidity.
We should pay attention to these factors and experiment with different brewing methods to find our preferred taste profile. Knowing the different factors that contribute to acidity levels in espresso can help us appreciate the complexity of coffee and gain a deeper understanding of the craft.
Different types of coffee beans have varying acidity levels. For instance, Two coffees grown in the same region and roasted the same way can have completely different levels of acidity.
For example, Ethiopian coffee varieties have a naturally high acidity level that is well-suited for light roasts. On the other hand, Brazilian coffee varieties are known for their low acidity, making them a good candidate for dark roasts.
The altitude at which the coffee is grown influences its acidity level. Beans grown at higher altitudes tend to have higher acidity levels. For instance, coffee beans grown in Colombia or Kenyan highlands have moderate to high acidity levels. Lower-altitude coffee, grown in places like Indonesia or Brazil, has moderate to low acidity levels.
3. Processing Method:
Espresso acidity is also affected by the coffee processing method. The dry or natural process can produce notes of blueberries and strawberries due to fermentation. This process also produces higher acidity levels in the final product. In contrast, the wet or washed method, which involves fully washing the coffee bean, produces a mild flavor profile with low acidity, making it suitable for espresso blends.
4. Roast Level:
Roast level plays a prominent role in determining the acidity level of the espresso. A lighter roast produces higher acidity, as less of the organic acids are burned off. Dark roasts have lower acidity levels, resulting in a more bitter taste. Medium roasts are often the most balanced in terms of acidity levels.
The reason for this is because during the roasting process, chemical changes occur in the beans. Organic acids break down as the beans are roasted, transforming into other compounds that affect the taste and acidity of the coffee.
What Makes Espresso Less Acidic Than Cold Brew Coffee?
Espresso is known to be less acidic than cold brew coffee, and several factors contribute to this. One of these factors is the roasting process, which involves heating the coffee beans at high temperatures. The longer the roasting time, the less acidic the coffee beans will be. Espresso beans are roasted for a relatively long time compared to other coffee types, which means that they have a low acidity level.
Espresso Acidity vs Drip Coffee Acidity
While both espresso and drip coffee contain acids, they differ in their levels of acidity due to factors such as the type of beans used, roasting process, and brewing method.
Espresso has a lower acidity level than drip coffee due to the faster extraction process resulting in a stronger flavor and lower acidity. However, drip coffee is more customizable and allows for more control over brewing factors, which can help reduce acidity levels.
Recommendations for Reducing Espresso Acidity

The two main types of coffee beans are Arabica and Robusta. Arabica beans are generally considered to have a milder, sweeter flavor, while Robusta beans tend to be more bitter and earthy. One of the biggest differences between the two is their acidity levels. Arabica beans have a lower acidity level than Robusta beans, which means they’re less likely to cause heartburn or stomach issues. Robusta beans, on the other hand, generally have a higher acidity level. This can give your espresso a bold, strong taste, but it can also cause acidity-related issues if you’re not used to drinking high-acid coffee. If you’re looking to reduce the acidity of your espresso, then Arabica beans are a good choice.
Typically, coffee beans from Brazil, Guatemala, or Sumatra have a lower level of acidity compared to other coffee beans. Therefore, choose high-quality coffee beans that are of the desired roast level for your espresso.
2. Regional Variations
The acidity level of coffee can also vary depending on the region in which it was grown. Countries like Kenya are known for producing high-acid coffee beans, while regions like Sumatra produce low-acid coffee beans. Coffee grown at higher elevations also tends to have higher acidity levels. This is because the beans take longer to ripen, which gives them more time to develop acids. If you’re looking for a low-acid espresso, then choosing beans from Sumatra or other low-acid regions is a good idea.
3. Use Filtered Water
Filtered water helps remove minerals and impurities that lead to acidity, resulting in a smoother taste. When selecting bottled or filtered water for espresso, look for water with a pH level between 6.5 and 7.5, creating the perfect balance in taste. Paying attention to the TDS (total dissolved solids) levels in the water is also crucial, as it can significantly influence flavor and aroma.
- The Effects of Hard Water on Espresso: Hard water has a high calcium and magnesium content that can increase the acidity in your espresso shot. High mineral content affects pH levels, which leads to a tart and harsh taste. It can also cause limescale buildup in your machine, affecting the quality and lifespan of your equipment.
- The Effects of Soft Water on Espresso: While soft water may seem like a better alternative, it can produce a higher acidity profile in your espresso shot. Soft water is high in sodium, which can also impact pH balance and create a sour taste. High sodium levels in soft water can lead to adverse health effects such as high blood pressure, making it less healthy for daily consumption.
4. Lower Water Temperature
Water temperature plays a crucial role in reducing espresso acidity. Expert barista suggest that a temperature range of 94-96°C or 201-204°F is ideal for preparing espresso shots. Lower temperatures ranging from 90-94°C or 194-201°F can reduce the acidity of espresso significantly. Controlling water temperature. There are various methods and tools for controlling water temperature when brewing espresso. You can preheat your machine and portafilter, adjust the thermostat, or use a thermometer.
Additionally, you can use a temperature-controlled kettle or device for consistency and accuracy. Such tools help you achieve your desired temperature setting, leading to a perfect espresso shot.
However, ensure that you use a stable power source, measure the temperature at different stages of the brewing process, and allow some temperature variation based on personal preference or coffee characteristics.
5. Coffee-to-water ratio (Using Fewer Coffee Beans)
Coffee-to-water ratio is one of the most crucial factors that affect espresso acidity. The more coffee you use for a fixed amount of water, the higher the acidity will be. A general standard is 1:2, which means 1 gram of coffee for every 2 grams of water.
If you find your espresso too acidic, consider using less coffee or more water. You can also adjust the grind size to compensate for the change in ratio, which leads to more balanced flavors.
6. Finer Grind
Grinding your coffee beans correctly can also make a difference in the taste and acidity of your espresso. A finer grind will increase the amount of acidity in your cup, while a coarser grind will reduce acidity. To make espresso with fewer coffee beans, you should grind your coffee beans finer than you would for brewing coffee using a drip coffee maker.
7. Extraction Time and Pressure
Extraction time and pressure are also significant contributors to espresso acidity. If the extraction time is too short or the pressure is too high, the coffee will be over-extracted, causing more acidity.
Conversely, if the extraction time is too long or the pressure is too low, the coffee will be under-extracted, resulting in sour and weak flavors.
Adjusting these parameters can be a bit challenging, but you can start by experimenting with different settings on your espresso machine.
8. Tamping and distribution
Tamping and distribution are often overlooked but can make a significant difference in espresso acidity. Tamping is the process of compressing the ground coffee into a solid puck, which affects the rate and consistency of water flow.
If the puck is unevenly compacted, some parts will extract faster than others, leading to imbalanced flavors and acidity. Ensure that your tamp is even and consistent every time, and distribute the coffee grounds evenly in the portafilter to prevent channeling.
9. Adding Milk
When milk is added to espresso, it can effectively neutralize the acidity. The proteins in milk also help bind with the acidic compounds in espresso, reducing the overall acidity even further.
Types of Milk and their Effect on Espresso Acidity: Not all milk is created equal when it comes to reducing espresso acidity. Whole milk tends to be the most effective due to its higher fat content, which allows it to more easily neutralize the espresso’s acidity.
