1.Source Of The Coffee Beans

Go For Arabica Beans, comparatively Robusta beans are more acidic than Arabica coffee beans, making it a great choice to keep your coffee less acidic. Also, the extra caffeine in robusta beans makes your stomach more susceptible to acid reflux and heartburn. 

Hence, switching to 100% arabica coffee automatically makes you drink a far superior cup of coffee.

A few coffee brands treat coffee beans differently so the final product will contain less acid, but these Low Acid Coffee beans still retain full flavor. By roasting the beans very slowly or simply interrupting the roasting process, each bean’s amount of acidity is significantly reduced.

Coffee tastes more acidic when grown at high altitudes, coffee beans grown at low elevations contain less acid than those grown higher up in mountainous regions. Knowing where the coffee bean was grown can provide you with a naturally low acid coffee, if you want less acidic beans, try low elevation arabica beans.

Try Different Coffee Growing Regions, as coffee grown in Kenya tends to be more acidic whereas countries like Brazil, Mexico, Sumatra, and Nicaragua have coffee beans with low acidity.

2.What To Add In Coffee to Reduce Acidity?

Adding Baking Soda helps reduce acidity in coffee. Baking Soda is Alkaline so it helps to lower the acidity of Coffee. Tends to neutralize some of the naturally occurring acids in coffee, just add ¼ teaspoon for a pot of coffee to make the flavor smooth and easy to digest.

Acid Reducers are a great source to reduce acidity in coffee particularly if you have an extremely sensitive stomach to coffee acid, this is a quick solution to try for, as it causes a chemical reaction to neutralize coffee acids. To ensure your cup of coffee is always to your liking try this as these acid reducers can remove 90% of acidity from your coffee. One thing to keep in mind, these are not antacids. It’s a proactive method to not let coffee’s acid upset your stomach.

Adding Milk or Cream is another best way to lower the acid levels in the coffee if you do like your coffee with additives. Milk or cream helps neutralize some of the acidity. The calcium in these components helps balance out the coffee’s pH, making it less acidic.

It doesn’t matter what brewing process you use, adding a pinch of salt to your cup helps reduce the acidity and also neutralize the bitterness of coffee, doesn’t affect the pH of the beverage but it works. If you have no other methods available, use a pinch in your cup — if you’re measuring, start with 1/16th of a teaspoon and go up to no more than 1/8th of a teaspoon to avoid a salty flavor.

To increase the effectiveness of adding salt to your coffee, use a dark roasted blend.

Use Egg Shells to decrease acidity in coffee, I know it sounds weird, but eggshells are alkaline, so adding them in your brewing process works to neutralize acids, balance the bitterness and over-extracted flavors in coffee. Using eggshells while brewing your coffee will also reduce any bitter taste that it has as a result of the brewing method you choose or the roast of the beans.

Before you use these shells, make sure to properly clean and sundry.

Almond Milk is an extremely healthy alternative to make your coffee less acidic, assuming you are not allergic to nuts, almond milk is a good choice for a non-dairy milk product as it has an alkaline composition, which can help neutralize stomach acid and relieve acid reflux symptoms, but make sure to avoid pouring cold almond milk into very hot coffee.

Though Cinnamon is unproven to reduce acidity, adding cinnamon to your coffee also may lessen the production of stomach acid and could be something to try, for those who suffer from acid reflux. (technically, cinnamon does not reduce acidity in coffee)

3.Water – Major Factor

The coffee that you drink has about 94-98% water. Coffee’s change in taste primarily comes from a change in temperature while brewing it.

It means water used to brew coffee impacts the taste highly. Like Temperature, the hotness of water as exposing coffee grounds to hot water releases oils that won’t dissolve at a lower temperature. These oils are full of acidic compounds that give coffee its bitter bite. The hotter the water, the more swiftly extraction will happen but, too cool a water temperature and the acids won’t extract. 

Hard Water and mineral content of water can dramatically affect the flavour of the coffee. Especially magnesium and calcium. 

Use Alkaline water for brewing your coffee, the minerals found in it naturally helps balance the acidity and neutralize the bitterness of coffee giving it a bolder and richer taste. 

4.Which Roast to choose?

How the coffee is roasted determines the level of acidity, as this process breaks down the acids. 

Dark Roast coffee beans stay for a longer time or at a high temperature on the roasting machine, it means the beans will lose more moisture, making them dense, less caffeinated. A more single note in flavour and lower their chlorogenic acid levels.

As the time and heat remove different compounds from the coffee including organic acids, making the dark roast a less acid coffee.

5.Grind Finer to Reduce Acidity in Coffee

The smaller the ground, the greater the surface area exposed, which leads to more flavours and aromas being extracted. A coarse grind size will slow down the rate of extraction because of its less surface area. Using a coarse grind may result in a more acidic cup of coffee because of extraction. The moment water comes in contact with coffee, the flavour and aroma begin to diffuse into the water. 

Acidity is a particular symptom of under extracted coffee and will lead to a sour taste, which happens when your grind size is too coarse or brewing time is too short. 

Less acidic coffee? Grind finer, More acidic coffee? Grind coarser.

6.The Importance Of Extraction

Extraction is the speed at which flavors and aromas are extracted, brewing coffee is the procedure of extracting the soluble material in roasted & ground coffee, solubility and extraction can be affected by a wide range of things like Grind size, Water mineral content, Roast degree, and Brew methods.

Brew time is the amount of time the ground coffee spends in the water. The longer you brew coffee, the higher the level of caffeine in your beverage. Along with brew time, methods of brewing such as Cold Brew also helps to reduce acidity in coffee.

A healthier alternative to a regular hot brew coffee is cold brewing as it lowers acidity and may help heartburn and acid reflux. Steeping the coffee in cold water for 12-24 hours in a cold or room temperature results in a perfect cup of coffee with a smooth, rich and long shelf life. It produces coffee with a more rounded, less bitter taste, and it’s also favoured by many people who have problems with acid reflux or other digestive issues.

Cold brewing can effectively neutralize the acid in coffee because it uses cold rather than hot water to extract flavour from beans. As a result, much less acid is drawn into the finished brew. cold brew coffee has up to 70% less acid than a regular cup of coffee.

7.Use paper filter/avoid metal mesh to Decrease Acidity

You know that oils in coffee are the main culprit of acidic coffee and trapping them with a paper filter will reduce the acid in coffee. A paper filter will strain and refine most of the oils and other compounds that contribute to acidity in coffee.

8.Drink Freshly Brewed Coffee

The chemical reaction in coffee occurs once it has been brewed, and continues to happen. That is why drinking freshly brewed coffee is one way to reduce the acidity of coffee. 

9.Limit Coffee Consumption 

If you like drinking a lot of coffee and don’t encounter any health issues, there is no reason to constrain drinking it. But if not so, a caffeine check is a must to ensure healthy lifestyle changes.


In short, choose dark roast over light roast, drink cold brew instead of hot, increase brew time – maybe use a french press, go for a finer grind, and brew at a lower temperature. The wonderful thing about brewing our coffee is that we get to drink it exactly the way we like it. If you are like me and love to explore every type of beverage in the world of coffee, go ahead, give these a try.

Frequently Asked Questions (FAQ’S)

What is Alkaline Water?

Alkaline water as the name suggests is “Alkaline” in nature with a pH of 8+, can be naturally found or artificially made by a chemical process called electrolysis.

Helps Boost Immunity, neutralise the acid in the bloodstream, neutralise the acidity caused by poor diet, stress and environmental toxins. 

Drinking Alkaline water daily helps with acid reflux. However, drinking excess of Alkaline water results in Metabolic Alkalosis.

What Is The Best Temperature To Make Coffee?

The best temperature to make a coffee is to heat water between 195 – 205 degrees Fahrenheit for optimal extraction. Too hot water will lose quality in the taste, while cold water will result in flat or under-extracted coffee.

Coffee’s change in taste primarily comes from a change in temperature while brewing it. Exposing coffee grounds to hot water releases oils that won’t dissolve at low-temperature. These oils are full of acidic compounds that give coffee its bitter bite but come along with the acid shock.

The hotter the water, the more swiftly the extraction will happen – but too cool a water temperature and the acids won’t extract. 

How Do You Test The Acidity In Coffee?

Acidity in Coffee can be tested in two ways, using a pH scale and the mouthfeel after you drink it, if the reading on pH scale falls below 7, it is considered as acidic. And after a sip of coffee, if you feel tartness on the sides of your tongue. Heartburn or an unpleasant feeling in your stomach, it also means the coffee you are drinking is highly acidic. 

Does Salt Reduce Acidity In Coffee?  

Adding salt in coffee helps reduce coffee acidity. By neutralising the bitterness and making it easier to drink without tangy taste on the sides of your tongue. Though it doesn’t change the pH level of coffee, putting in a pinch of salt helps relish coffee then. 

Does Milk Reduce Acidity In Coffee?

Milk decreases acidity in coffee because of its components. A chemical reaction between calcium in milk helps neutralize the acids in coffee. 

On the other hand, nut Milk like Almond milk reduces acidity due to its alkaline nature. Making almond milk a great option for people who avoid dairy products and assists in reducing acid reflux.
