What is Low Acid Coffee?

Low acid coffee is coffee that contains lower levels of chlorogenic acid, reducing bitterness and acidity that can cause stomach discomfort. It is produced by selecting low-acid beans, slow-roasting, or using cold-brew methods. This coffee is ideal for people sensitive to acidic drinks.

Well, since coffee consumption has grown vastly over the last decade, more and more people rely on their caffeine-fuelled beverage every day. That kick-start out of bed in the morning provides the long-lasting energy boost you need.

Low-acid coffee is defined as having low or very moderate levels of quinic acid. Therefore, the PH level within low acid coffee is situated much closer to neutral than what you'd find in regular brewed coffee.

You could also describe this kind of coffee as being more gentle on your stomach which is particularly important if you're searching for speciality coffee that doesn't make you feel uncomfortable.

Let's find out the science behind this method and more importantly, how you can get your hands on it.

Where Does Acid in Coffee Come From?

The Science:

In order to understand how to make low acid coffee, we need to dive a little deeper into the science to truly understand what's at play when we're talking about acidity.

Nine acids are released when freshly ground coffee is brewed with hot water. It's these acids which also contribute to the flavour you experience when you sip on your favourite coffee.

• Citric
• Chlorogenic
• Quinic
• Lactic
• Acetic
• Malic
• Phosphoric
• Linoleic
• Palmitic acids

Factors that Affect Acidity in Coffee

Coffee Roast Profile

The coffee roasting process is one of the most significant aspects of coffee acidity. Simply put, the length of time the coffee is roasted for plays a vital role in how high or low in acidity a given coffee produces.

As a rule of thumb, the darker the coffee roast is, the lower the levels of Chlorogenic acid produced, meaning it should produce less acidity when it comes to brewing.



This is an important learning and factor when you're choosing where to buy your coffee online.

It means you can carefully filter through the best speciality coffee roasters to find the right coffee roast that suits your preferences. 

Head to our popular blog on the differences between light and dark roasts if you want to learn more about this topic.

Altitude, Processing Methods

The specific farm and altitude at which the coffee is grown also play a part in the acidity created. How is this so?

As a result, of higher altitude conditions, coffee matures at a slow rate, creating more sugars and complexity that is created.

For example, unique coffee varietals like the famous Panama Geisha exhibit floral jasmine notes, making this type of coffee one to avoid if you're looking for low-acidity coffee.

Coffee Origin

Does the country a coffee is grown in impact the acidity levels in the coffee? Absolutely.

The coffee's origin and, therefore, climate conditions are a major contributing factor to the flavour you taste in your daily coffee fix.

It's important to consider because the top five coffee-producing countries worldwide are where you'll most commonly find coffee.

So if you're looking to avoid a particular origin, then you'll need to do more research than the average Joe. Here are some examples of coffee origins that we know have naturally lower acidity based on their growing conditions.

That way, you can get closer to your goal of buying coffee in the UK lower in acidity.

1. Brazil

2. Sumatra

3. Nicaragua

Brewing Process

The coffee brewing process plays a big role in producing more or less acidity in coffee too. But how?

Studies produced demonstrate that the shorter the brew time, the more acidity produced in the coffee. That makes sense when talking about extraction time in general.

If a coffee is 'under-extracted' or brewed too quickly, it'll produce astringency, which can give the drink greater acidity.

Size of the Coffee Grounds

Did you know that the size of the coffee grounds you use contributes to the acidity of your coffee?

Yes, it's true. Studies by the NIH show that the finer the coffee grounds are (E.g., Espresso), the more acidity is extracted. By contrast, the coarser the coffee grounds are (larger particle size), the less acidic they are.

This means you may want to change your brewing method to see if that helps with your sensitivity to coffee. Here is a useful list of ways to make coffee from least acidic to most acidic based on brewing method.
