Coffee has various acids that improve the flavors, and without any acidity, it wouldn’t taste the same. But if it’s too acidic, you’re not going to like it much, and it’s probably going to leave you with heartburn. 

But you don’t have to drink coffee that’s too acidic, because here we’re showing you the best way to make coffee that’s less acidic. They range from carefully picking the beans to applying salt to the brewed coffee. 

So if you don’t like coffee that’s too acidic or has any health problems such as gastroesophageal reflux disease, there are various solutions that you can apply to make your brews less acidic. 

Best Ways to Make Less Acid Coffee 

Some coffee lovers have a digestive system that doesn’t give the acids a good coffee cup, so any cup of coffee they take can be rather nasty. 

But coffee acidity does not stop you from enjoying your favorite cup of java, as we explain below how to reduce the acidity of your coffee. 

1. Use arabica beans 

Arabica coffee beans are usually less acidic than robust coffee beans. So simply moving from Robusta to Arabica will make your coffee much less acidic. 

However, Arabica coffee beans have considerable acidity, which could still be troublesome for coffee lovers. The use of Arabica coffee beans is a perfect starting point for making your coffee less acidic. However, it is important to remember that they will contain slightly lower caffeine content. Robusta beans have around 2.7 percent caffeine, while Arabica would have around 1.5 percent caffeine. 

So you’re going to have to decide if you’re comfortable with losing some caffeine boost to make your drink less acidic.

2. Low altitude

Coffee growing at low altitudes would have less acidity than coffee grown at high altitudes in the mountainous area. Thus, although high-altitude coffee appears to be more flavorful, it will also come with a higher dose of acids.

Simply selecting low-level beans will greatly reduce the acidity of your coffee. Therefore, it is also important to know where the beans you use for your coffee are made, as this will give you an idea of how acidic they will be. Most Arabica coffee beans grow at high altitudes of up to 2,000 meters above sea level, while Robusta beans grow just below 900 meters above sea level. However, Robusta is also going to contain caffeine.

This means that if you search for less acidic beans, you can go to low altitude Arabica coffee because the plants will still thrive at a low altitude of just over 900 meters above sea level. 

This means that if you search for less acidic beans, you can go to low altitude Arabica coffee because the plants will still thrive at a low altitude of just over 900 meters above sea level.

Costa Rican coffee, which grows a little over 1,300 feet above sea level, is a good example of low-level Arabica coffee. It appears to be less acidic than coffee from other high-level growing regions in Ethiopia and Kenya.

3. Dark roast coffee

How you toast your coffee will also decide the acidity level as the toasting process breaks down the acids. And so it should be apparent that the dark roast will be less acidic than the light roast since the longer roasting time and the high heat will extract various compounds from the coffee, including the acids.

Light roasts are also referred to as bright, and the acidity of the coffee is emphasized. This roast gets its brightness from the acids in the coffee, such as malic acid, and it’s also one of the things that give it the citrus fruit taste.

And while light and medium roasts are becoming increasingly popular as more and more coffee lovers choose to brew single-origin coffee beans, it’s best to avoid them if you hate acidic coffee.

On the other side, dark roasts will contain less acid as a significant portion of the coffee beans’ organic acids will be eliminated during roasting. 

4. Cold brew method

Making your coffee also influences acidity since certain methods are known to emphasize acidity, and others, such as cold brewing, will inhibit it. So if you want to know how to neutralize the acid in your coffee, you can start by learning how to make a cold brew.

Cold brewing is a slow process that can take up to 24 hours, so if you want your coffee to be less acidic when using this form, you must be careful and prepare it in advance.

Soaking your coffee in cold water during cold brewing will ensure that the organic acids are not over-extracted. When brewing with hot water, the acids are quickly extracted because the high temperature makes it easier for the coffee to release them. With cold water, it’s getting harder for coffee oils to produce acids.

Using cold water to brew your coffee, you’ll end up with coffee that’s up to 70% less acidic when you equate it to hot water. The only downside with cold brewing is that you can’t depend on it if you want a fast cup of coffee.

5. Acid reducer

One of the best ways to lessen the acid levels in your coffee is to induce a chemical reaction that induces neutralization of some of the acids using an acid reducer.

Acid reducers are readily available and low-cost, and if you’re a frequent coffee drinker, you should have them around as they help ensure that your coffee cup is still up to your taste.

The acid reducer decreases the amount of acidity in your coffee and does so without affecting the taste. And if you have a good quality one, it will minimize your coffee’s acidity by up to an amazing 90%, meaning that you don’t get acid reflux.

The acid reducer can operate by linking the acids in your coffee together to make them less abundant to ensure that your stomach does not get irritated after drinking the coffee. However, remember that they are not antacids but rather a preventive step to minimize acidity before drinking coffee.

6. Using eggshell

Despite sounding a little odd, eggshells are a great way to reduce your coffee’s acidity, and besides being an easy process, they’re still one of the most effective.

Considering that eggshells are alkaline, they can neutralize acids, and organic acids in coffee are no exception. And better still, the use of eggshells often tends to make the coffee less bitter, which may be caused by an over-dark roast or over-steeping coffee grounds.

You should take one or a few eggshells for this process, rinse them thoroughly on the sink, and then smash them well with your fingers before adding them to your coffee making setup. Now, brew the coffee like you usually would, and it should be less acidic and less salty.

But when you’re using eggshells, you need to be careful enough that any of them can quickly end up in your coffee cup, which can be irritating.

7. A pinch of salt

A splash of salt can also help to solve the issue of coffee acidity. And the great thing about salt is that you can either apply it to the brewed coffee on your mug or during the brewing process.

Like eggshells, a splash of salt can not only smooth out your acidic coffee, but it can also help to reduce the bitterness of your coffee. Salt is alkaline, so it’s easy to neutralize acidity.

However, you have to be careful about how much you’re using because you can easily end up with a salty taste on your coffee cup if you’re using too much of it.

This approach is the simplest and most convenient, as salt is still present in most homes. In addition to salt, you should also use baking soda since it is also extremely alkaline and can also neutralize acidity.

8. Make a hard water coffee

Filtered water still provides the highest quality coffee, so it’s hard to imagine producing your java cup of hard water. However, if you have a major problem with acidity, it would be better than soft water.

Hard water contains many minerals such as calcium, which can quickly neutralize the coffee’s acidity or overshadow it, making it less prevalent.

On the other side, soft water is one of the key minerals that make the coffee brighter’s acidity brighter when used in brewing—soft water.

9. Using your paper filter

When using a coffee-making process that involves a filter, you can use a paper filter instead of a metal mesh to reduce your coffee’s acidity.

Paper filters will often have a cleaner and lighter coffee cup as they trap much of the coffee’s oils and fats. These oils and fats release acids into your coffee, so the paper filter can contribute to making your coffee less acidic by trapping them.

10. Add milk.

If you have no question about including additives and lightnings in your coffee, you can also neutralize acidity by adding milk or even cream.

Calcium can help balance the pH of the coffee and reduce its acidity in these dairy products. This approach would work best when using dark roasts because light roasts do not take milk well because of their high acidity.


Coffee that is too acidic is less flavorful and comes with unpleasant issues such as acid reflux. But acidity shouldn’t be the only ground for missing your dose of caffeine as you can repair it quickly.

In this article, we’ve described some of the best ways to make coffee less acidic, and you can be sure that at least one of the above ten methods will work for you.

However, the best idea is to try various methods of reducing acids before finding the one that gives you the best quality and taste of the coffee.
