Coffee in nature is acidic due to the powerful antioxidants it contain

Coffee is naturally acidic which makes it have a sharp flavor which is what many people love about it.  This natural acid in coffee has powerful antioxidants which makes coffee one of the healthy drinks out there.

However, some people like me don’t like taking extremely acidic coffee due to the heartburn effect it causes after drinking. I prefer coffee with less acidity because it has a naturally sweeter taste and I will not have to worry about any effects after enjoying a cup of coffee.

So, how can you reduce acidity when making coffee? If you don’t like the sour taste in coffee caused by acids or if they affect you negatively, below are 12 ways to make coffee less acidic.

1. Cold Brewing

You need to be patient or prepare your coffee in advance if you want to reduce acidity with this method. However, it is highly effective and will leave you with a sweet-tasting cup of coffee. The method entails soaking ground coffee beans in cold water for a minimum of 24 hours.

Cold water doesn’t extract natural acids in coffee as fast as hot water does. The acidity in coffee is mostly a result of oils in the coffee beans. These oils will require high temperatures to release the acids, but with cold brewing, that is not possible.

As a result, you will end up with a cup of coffee with around 70 percent less acid compared to coffee made through hot brewing. One thing you have to note about this approach of making the coffee less acidic is that you cannot rely on it when you want a cup of coffee in a hurry.

The extraction process is slowed by cold water which means if you are not patient enough, you will end up with a tasteless cup of coffee. Make plans accordingly and soak the coffee a day ahead.

2. Control Water Temperatures

When you want to hot-brew your coffee, you need to control the temperature of the water. The higher the temperatures, the easier it will be for oils in coffee to release acids.

Avoid reaching extreme temperatures when making coffee through hot-brewing to avoid over-extraction. This will make your coffee less acidic.

3. Mix With Eggshells

Are you surprised that an eggshell can make coffee less acidic? You don’t have to wonder anymore. This method uses simple chemistry to ensure you enjoy a sweet-tasting cup of coffee.

Eggshells are rich in calcium which is alkaline. This means they can neutralize any acid including the ones found in coffee.

To get started, take one or two eggshells and wash them well to get rid of any egg remains. Trust me if you mix a raw egg with coffee, you will hate drinking coffee for the rest of your life. After proper cleaning, crush the eggshells and then add them to the coffee grounds.

Then brew your coffee as you usually do. You will end up with a less acidic coffee with a cleaner taste and won’t cause you acid reflux afterward. The best thing with this approach is that the excess calcium that won’t be used in neutralizing the acid will be used in strengthening your bones and teeth when you drink your coffee.

Tip: Try the best teas for acid reflux

4. Using Salt/Baking Soda

How on earth can you add salt or baking soda to coffee in the name of reducing acidity? Well, I was wondering the same too until I tried it. Well, baking soda/salt can work magic in reducing acidity in your coffee when you use it in the right quantity.

Baking soda is highly alkaline with a PH of nine. This means it will neutralize the acids in coffee to give you a cup of coffee with less acid. You should remember to add a pinch in your cup to avoid getting a salty flavor in your coffee.

This is one of the best ways to make coffee less acidic because salt is easily available in most households. Besides, it doesn’t require you to follow a complicated process. However, if you want to increase the effectiveness of this method, you should use a dark roasted blend.

5. Use Acid Reducer Products

There are some products you can buy and add to your coffee to make it less acidic. These products work the same way as the eggshells and the salt – triggering a chemical reaction. The only difference is that these products are more effective where they reduce almost 90% of the acid in coffee.

If you drink coffee frequently or if you want to make coffee with less acid when on the move, using these products can be the best solution. Coffee tamer on Amazon is an example of such products.

6. Avoid Leaving Your Coffee In Thermos

Always avoid leaving your coffee in a thermos or any other place that it is going to remain hot for too long. Keeping your coffee hot for long after brewing will make the oils release acids which will increase its acidity.

Even if you won’t drink all the coffee that you have to make, cooling it before storing is a good idea. You can warm it later when you want to drink it.

7. Use Hard Water To Make Coffee

Water makes the better of your coffee which means the water you use to make your coffee dictates the end product regarding flavor, taste, and acidity. You should use hard water to make coffee if possible if you want it to be less acidic.

This is because hard water is rich in minerals like calcium which will either neutralize the acids in the coffee or outshine them and make them unnoticeable. Soft water, on the other hand, doesn’t have many minerals. Instead, it has high sodium content which makes acidity shine when used to make coffee.

8. Use A Coffee Paper filter

When making your coffee through drip or pour-over methods, using a paper filter can reduce acidity in your coffee. The filter paper will trap oils and fats that release acids into your coffee. This method will also filter out other sediments which leave you with a smooth, sweet-tasting coffee.

9. User Finer Grind To Make Coffee

When you use coarse grind to make coffee, the rate of extraction is slowed down because they have less surface area. Finer grind, on the other hand, has a large surface area which will accelerate the rate of extraction (Speed of aroma and flavor extraction). So, if you want to make coffee less acidic, grind finer.

10. Shorten Brew Time

The amount of time the coffee beans stay in water can determine the acidity of the coffee you will make. The more they stay in the water, the more the extraction. Ensure you shorten the brew time to make your coffee less acidic.

11. Choose Processed Coffee Or One With Low Acids

Some coffees come when processed to get rid of acidity. Others have low acid naturally because of the place they are grown. The processed ones are treated with steam or solvents to minimize the amount of acid they have.

Coffee grown in specific parts have low acid which means even your cup will be less acidic. Brazilian, Indian, Hawaiian, and most Caribbean coffees are examples of coffees that are low in acid naturally.

You can read the descriptions before purchasing to see the acidity level and the region it’s grown. This saves you from the trouble of adding other elements or going through complicated processes to reduce acidity in coffee when making it.

You can also enjoy a cup of coffee when you are in a hurry without the worry of suffering from negative effects like acid reflux afterwards.

12. Go For Dark Roast Coffee

Choosing dark roast coffee over medium or light roast coffee is another excellent way of ensuring your cup of coffee will have less acidity. The dark coffee has been roasted for a long time, undergone chemical changes hence less acidic.

Too much caffeine is one factor that makes a coffee highly acidic. Well, dark roast coffee has less caffeine compared to lighter roasts which makes it less acidic. Therefore, if you want to make less acidic coffee, go for dark roast coffee.
