10 Simple Methods to Reduce Coffee Acidity Naturally

10 Ways to Reduce Coffee Acidity

Coffee is a favorite beverage enjoyed by millions of people worldwide. However, for some individuals, high-acidic coffee can lead to an unpleasant experience, causing heartburn or stomach discomfort.

Luckily, there are a few methods you can use to reduce coffee acidity. In this article, we will delve into ten of these methods and provide you with insight on how to use them.

1. Baking Soda

Baking soda, or sodium bicarbonate, has an alkaline property that can neutralize the acid in coffee.

To use this method, start by brewing coffee as usual. Add a pinch of baking soda per cup of coffee to the brew.

You can gradually increase the amount of baking soda until the acidity taste is reduced. However, be careful not to use too much baking soda.

If you do, it can alter the coffee’s taste and cause heartburn.

2. Acid Reducers

If you have high sensitivity to acid, consider using acid reducers. These over-the-counter medications can reduce the amount of acid in your stomach, making it easier to drink coffee.

Experts recommend taking the medication 20-30 minutes before having coffee for the best effect. You can also opt for low-acid coffee, which contains 90% less acid than regular coffee.

3. Paper Filters

Using paper filters can help reduce the amount of acid in coffee by collecting the coffee oil that carries the acid.

To use this method, brew coffee with a paper filter, and discard the filter after each use. This technique will produce a smoother and less acidic coffee taste.

4. Temperature

The temperature of water used in brewing coffee can also affect its acidity level.

Generally, the higher the temperature, the more acidic the coffee. Experts recommend using cooler water, between 195F to 205F, to reduce the coffee’s acid content.

5. Water

Hard water, which contains more minerals, can produce a coffee with a higher acidic content.

Using soft water, which contains less mineral and salt, can reduce the acidity level of coffee. You can also use filtered water to reduce the amount of minerals in the water.

6. Natural Alternatives

Another way to reduce coffee acidity is by using low-acid coffee blends or specialized mixes.

These coffee blends have a naturally low acidity level, making them easier to consume. Some popular low-acid coffee blends are Brazilian and Sumatran coffee beans.

7. Cold Brew

Cold-brewed coffee is another excellent method to reduce coffee acidity.

The cold water used in brewing coffee over a long period can help reduce the acidic content. To make a cold brew, mix coarsely ground coffee with cold water, and let it sit overnight before straining it with a fine-mesh strainer or cheesecloth.

8. Coarser Grounds

The coarseness of coffee grounds used in brewing coffee can also affect its acidity level.

Finely ground coffee beans produce more acidic coffee than coarsely ground beans. If you’re using a drip coffee maker, choose a medium to coarse grind for a less acidic coffee.

9. Refrigerate the Pitcher

Refrigerating the coffee pitcher can help reduce the acidic content.

After brewing coffee, transfer it to a pitcher and let it cool to room temperature. Then, refrigerate it overnight, allowing the coffee’s flavors to develop while reducing the acidity level.

10. Use Egg Shells

Using eggshells in brewing coffee may sound bizarre, but it’s surprisingly effective in reducing acidity.

Boiling crushed eggshells in coffee can help neutralize the acids, reducing the discomfort. Here’s how to do it:

Boiling Coffee with Eggshells


  • Water
  • Medium-ground coffee
  • Crushed eggshells


  1. Add cold water to a non-reactive pan.
  2. Mix medium-ground coffee and crushed eggshells in a separate bowl.
  3. Add the coffee mixture to the water and stir.
  4. Bring the water to boil and let it boil for 5-7 minutes, occasionally stirring.
  5. Remove the pan from heat and let it sit for a few minutes for the coffee grounds to settle.
  6. Pour the coffee into a cup through a fine-mesh strainer.


In conclusion, acidity can affect coffee taste and cause discomfort for some individuals. However, by using the ten methods mentioned above, you can reduce coffee acidity and enjoy a smooth and balanced taste.

Experiment with different methods and find the one that works best for your taste buds. Remember, if you’re experiencing severe discomfort, it’s best to consult a healthcare professional.

In summary, reducing coffee acidity is crucial for individuals who experience discomfort or heartburn after drinking coffee. We presented ten effective methods to reduce acidity, including adding baking soda, using acid reducers, using paper filters, controlling water temperature, choosing soft water, using low-acid coffee blends, opting for cold brew, using coarser grounds, refrigerating the coffee pitcher, and boiling coffee with eggshells.

These methods can help individuals enjoy a smoother and less acidic coffee experience. Remember to consult a healthcare professional if you experience severe discomfort.
