Ultimate Guide to the Lowest Acidity Coffee in 2019

For many of us, freshly brewed coffee is the sustenance of life. Not only does it taste great, there is much research showing the health benefits of coffee.

Unfortunately coffee is also thought to contribute to digestion issues such as heartburn, acid reflux, indigestion and Gastroesophageal reflux disease (GERD) for some people.

If you suffer from pesky digestion issues it may still be possible to enjoy a daily cuppa by switching to the lowest acidity coffee. Here we share some of the best low acid coffee brands available for you to try.

What is Coffee Acidity?

First, what exactly do we mean by acidity in coffee? Acidity refers to two different things.

PH Level

PH level is what we all know from doing basic chemistry in school.

The lower the PH level the more acidic something is. So drinks like orange juice and soda come in at around a 4. Water is right in the middle at 7.

Is Coffee Acidic Or Alkaline? 

Coffee acidity ph tends to fall in the range from 4.5-5.5. So you will notice that coffee, while more acidic than water, is far less acidic than juice or some sodas.

Many low acid coffee brands highlight the PH level of their coffee beans. While not the most important factor, it is one way of comparing acid in coffee.

Flavor Notes

The more common interpretation of coffee and acidity is to do with the flavor notes in coffee beans.

This is also known as brightness, tartness, aroma and bitterness – basically what makes coffee, well coffee.

Coffee is made up of over 30 different organic acids.  These acids combine to produce the unique flavor attributed to coffee. They are also responsible for many of the benefits of coffee such as antioxidants.

However it is some of these organic acids that are thought to link coffee and acid reflux.

Two particularly troublesome compounds seem to be chlorogenic acid (which gives coffee its brightness) and caffeine.

So when we talk about low acidity coffee it is the flavor notes we are really talking about. The PH of coffee, whilst variable, is of less significance.

What Makes Coffee Low Acid?

While some beans are naturally low in acidity, other factors such as the roasting process and brewing method also have a big impact on the overall acidity of coffee. Here we explain these factors in more detail to better understand what produces acid in coffee.

1. Region

The region and climate where coffee beans are grown has a big impact on the level of acid in coffee.

Coffee beans grown at higher elevations tend to have higher levels of organic acid and caffeine. A good example of this fruity brightness can be found in Ethiopian coffee.

This is quite different to coffee grown at lower elevations which tend to have a smooth and mellow flavor. Many naturally low acid coffee beans come from medium to low elevation regions such as Indonesia, Central America and Brazil.

2. Processing Method

Coffee beans can be processed in a number of different ways. The way they are processed contributes to the overall coffee acidity. The three most common processing methods are:

  • Wet/washed processing
  • Dry/natural methods
  • Semi washed/pulped processing.

Wet processing methods tend to result in a higher level of acidity. Dry processing methods (more common in hot climates such as Africa) tend to produce much lower acidity.

3. Roasting Process

The roasting process has a big impact on the level of coffee acidity.

Coffee bean acidity changes during the roasting process. During roasting the natural acids in coffee beans are broken down and change.

As a result, dark roast beans generally have lower levels of acidity than light and medium roast beans. A longer roasting time is also thought to result in:

  1. Lower levels of chlorogenic acid and caffeine
  2. An increase in the level of N-methylpyridinium (NMP) which is thought to suppress the release of gastric acid.

Some companies now use proprietary roasting methods to achieve low acidity. This often involves steaming or slow roasting the beans.

These methods reduce the release of acids that occurs in high temperature roasting. Unfortunately this can also impact the complexity and overall flavor of the coffee beans.

4. Brewing Method

When coffee is extracted through a high temperature method, such as an espresso machine, chemical reactions occur that may increase the acidity of coffee.

So one way you can enjoy coffee with low acidity is to try immersion brewing methods which tend to produce less acidic coffee.

Three popular immersion methods are:

  • French Press brewing;
  • Chemex pour over brewing and
  • Cold brewing methods

All three brewing styles tend to release less chlorogenic acid and caffeine. 

In fact cold brewing is thought to produce up to 70% less acid than hot water brewing methods.

If you are a fan of french press coffee see this list of top french press coffee beans.  For cold brew lovers, this list covers the best cold brew coffee beans.

So as you can see, there are a number of factors that contribute to the lowest acidity coffee.

However if you start with the right low acid coffee beans you are well on your way to brewing low acidity coffee.

Summary – How To Reduce Acidity In Coffee

Once you have settled on the best low acidity coffee beans, you can then focus on producing great tasting low acid coffee. To summarize what we have discussed, here is how to reduce acid in coffee:

Buy the Least Acidic Coffee Beans

  • Choose an organic medium to dark roast as these are considered to have the lowest acidity and are gentlest on the stomach. Our favorite is the Volcanica Sumatra Manheling. See it here.
  • Choose single origin whole beans from low elevation regions known to grow lower acidity beans. Look for Indonesia (Sumatra), Central America, Brazil and Hawaii.
  • For the ultimate treat try Kona Coffee beans which have some of the lowest natural acidity. See our favorite brands here.

Add Milk

If lactose intolerance isn’t an issue then try adding milk to your coffee. Milk is thought to reduce the impact of coffee acid on consumption as calcium offsets acidity in the stomach. Popular choices include a latte or cappuccino.

Drink Freshly Made Coffee

The chemical reactions in coffee continue once it has been brewed, which is why we recommend you drink fresh brewed coffee to reduce coffee acidity. Ever had a cup of coffee that was brewed hours ago? Generally not a pleasant experience. 

A good coffee maker that allows you to adjust the number of cups you require is the best way to reduce coffee waste.  See our top picks here.

Neutralize Coffee Acid

Consider adding an acid neutraliser treatment to your favourite brew. Popular coffee acid reducers include Coffee Tamer and CalciBlend. 

Try A Different Brewing Method

Trying a different brewing method is a good way to make coffee less acidic.

Two of the best low acid coffee brewing method options to lower overall coffee acidity levels are cold brew and pour over.  

The Chemex Pour Over coffee maker is a gorgeous looking coffee maker to add to your kitchen collection. See it here.

Cold brew acidity, whilst not differing in PH levels to hot coffee, seems to have less overall acidity present post brewing. This is possibly due to the method of extraction. Note however that you should still avoid using coffee beans with high caffeine levels as caffeine is a contributor to stomach issues for coffee drinkers.

Preparing cold brew coffee is very simple and cheap when using a customised mason jar like this this one or brew it in your french press!

Frequently Asked Questions

Is Dark Roast Coffee Less Acidic?

The coffee roasting process alters the chemical balance in coffee beans. So whilst the PH level of dark and light roasts may be the same, the coffee acidity will differ. Lighter roast beans tend to have more natural acidity. Darker roast coffee beans will tend to be less acidic.

Is Organic Coffee Less Acidic?

Coffee acidity relates to the PH level and natural chemical acidity found in coffee beans. Whilst the region will impact the level of acidity, organic production does not produce a less acidic coffee.

Is Decaf Coffee Acidic?

The short answer is yes, decaf coffee is acidic in the same way regular coffee is acidic.

Many people ask does decaf coffee have less acid than regular coffee. Many studies indicate most decaf coffees have a similar acidity profile to regular coffee. However where they are different is the level of caffeine. 

Caffeine may contribute to stomach issues, so whilst decaf coffee is acidic, the lower caffeine levels in decaf coffee may help coffee lovers with sensitive stomachs.
