Baking Soda in Coffee? Who Should Try it?

Not many people think about adding baking soda when it comes to making the perfect cup of coffee.

However, this unlikely ingredient may be just what you need for a smooth-tasting, less acidic brew full of flavor and easy on your stomach.

In this article, I’ll explore why some coffee lovers are adding a pinch of baking soda to their daily cups —and discover if it’s worth all the fuss.

Why would you mix coffee and baking soda?

It may seem like a strange combination at first, but mixing coffee and baking soda actually has some great benefits.

Key takeaways:

  • Baking soda is alkaline in nature, and adding it to your cup of joe will help balance out the acidity found naturally in coffee beans — making for an easier drinking experience. Sodium bicarbonate is known to help relieve heartburn symptoms caused by caffeine-induced stomach upset.
  • It also helps mask any bitter notes that might come with heavily roasted or old grounds while brightening up other existing flavors.
  • Please don’t overdo it, though! Too much leads to sodium imbalance in your body.

Acidity of Coffee

Coffee has a reputation for being an acidic beverage. It’s true that coffee has a pH of 4.85 to 5.10, which puts it firmly in the category of “a bit on the bitter side”!

Acidic Scale

Coffee contains an organic acid called chlorogenic acid, which is responsible for the taste of coffee, but it also contributes to its high acidity on the pH scale. This can be hard on your stomach if you drink too much or are generally sensitive to acids.

The lower your coffee’s pH level is, the more acerbic it might taste – which can leave you with an unpleasant aftertaste or cause digestive distress.

Alkalinity of Baking Soda

Baking soda is like an angel sent from the heavens to bring balance and harmony into coffee lovers’ lives!


Baking soda, or sodium bicarbonate, has a pH value of 8, which is on the alkaline end of the pH scale. Its alkaline nature brings a neutralizing effect that helps reduce the acidic levels of your morning cup, making it less bitter.

In other words, it works its magic by balancing out all those extra acidity molecules to deliver a smooth drink with fewer adverse effects on sensitive stomachs – almost as if Cupid was aiming his arrow directly at our hearts (or rather bellies!)

Smooths out bitterness

Very dark roast, stale, or inexpensive coffee can be overly bitter, and baking soda can make lousy coffee taste much better.

Scientific effect of mixing baking soda and coffee

When mixed together, the chemical reaction between the two compounds has an interesting scientific effect on both elements.

The reaction between baking soda and coffee is due to acids in the brewed beverage. When sodium bicarbonate comes into contact with acid, it neutralizes it by releasing carbon dioxide gas, producing a fizzy effect.

You may have done the classic volcano experiment in grade school, pouring baking soda onto acidic vinegar to make the volcano erupt. The same thing happens with coffee; acids are negated through the release of CO2. 

How Much Baking Soda Should You Put in Your Coffee?

Light roast coffee is more acidic than dark roast coffee. 

Baking Soda
  • For good quality darker roasts, add about 1/4 teaspoon per pot of coffee.
  • If you’re drinking a cup at a time, 1/8 tsp will be enough, and that’s about a pinch.
  • For lighter roasts with higher acidity levels, increase this ratio up to 1/2 teaspoon per 8 oz pot. But remember not to go overboard!

What does baking soda in coffee taste like?

Baking soda in coffee tastes…interesting. It doesn’t change the taste of your cup much, but it does mellow out any bitter flavors that may be present from a dark roast, while delivering a smooth texture and slightly salty aftertaste. The bitterness from the acidity is gone and replaced with subtle flavors that are not overpowering. You won’t be able to taste any hints of sodium bicarbonate.

If you’re looking to reduce acidity or bitterness without adding milk or sugar, baking soda is definitely worth trying.

Overdosing on baking soda

Putting too much baking soda in your coffee can create a sweetish salty flavor, creating an unpleasant taste for most people’s palates. Also, carbon dioxide gas is released, creating air bubbles inside your stomach. The result? You can expect symptoms like abdominal pain, bloating, and excessive wind passing (farting).

Additionally, baking soda contains sodium ions not found in regular table salt or sea salt crystals. If you consume way too much, your body will become overwhelmed by the amount of sodium it contains. This can lead to an imbalance in electrolytes inducing excessive urination and leading to symptoms such as nausea and vomiting, headaches, dizziness, or confusion due to dehydration.

This sounds scary, but if you don’t consume more than 1 teaspoon of baking soda per day, you have nothing to worry about.

Tangible health benefits of mixing coffee & baking soda

Baking soda has some general health benefits that are present if you mix it into your coffee as well.

Improves heartburn, acid reflux (GERD), and gut issues

Adding baking soda to your coffee can significantly reduce the discomfort of mild heartburn, acid reflux, and stomach ulcers.

Acid Reflux

As we all know, caffeine is naturally acidic, so it’s easy for our stomach acids to get out of balance. When this happens, heartburn or GERD occurs because there isn’t enough buffer in the esophagus anymore.

 Baking soda helps neutralize both these conditions due to its alkalinity: when mixed with warm water, it creates an environment where acid is somewhat negated. If you’re looking for relief from stomach aches and heartburn without resorting to medication, adding baking soda might be worth trying (in moderation).

However, you should know that caffeine has a direct effect on your esophageal sphincter. It loosens the muscle, which could result in stomach acids and fumes entering your esophagus, increasing GERD.

Baking soda has no calories

Not only does it help reduce the acidity in your cup of joe, but it also has no calories! Other sweeteners and creamers you might be adding to ease the acidity of coffee add plenty of extra needless fat and sugar into our lives.

Big Zero

Baking soda has no caloric content and will do you absolutely zero harm health-wise if used correctly.

Tips for making your baking soda coffee taste even better

  • Use quality freshly-ground coffee beans: The better the beans, the smoother and tastier your cup of Joe will be!
  • Go easy on adding baking soda: a pinch is enough to start with – too much could make it unbearably salty.
  • Add milk/cream to balance out the taste: you can avoid an overly acidic flavor by doing this step before adding baking powder so that the acidity doesn’t negate any added sweetness.
  • If needed add some sugar for sweetness but try not to go overboard.

Alternative ways to reduce acidity in your coffee

If you’re not a fan of baking soda on coffee, don’t worry. There are other ways to lower the acidity of your favorite brew:

  • Going decaf: A study has found that decaffeination of coffee significantly reduces the risk of acid reflux. Of course, the caveat here is that you won’t be getting the benefits of caffeine in your brew.
  • Cold brewing: Because of its unique method, cold brew coffee is also known to have less acidity compared to regular coffee, making it a better choice for those who have a more sensitive stomach.
  • Buy low-acid coffee beans or acid reducers: You can also purchase low-acid coffee beans or coffee acid reducers which can lower the acidity of your coffee without affecting its flavor.


No, there is no scientific evidence that baking soda helps you lose weight. Urban legends are not evidence.

If you use moderation, baking soda will not harm your body. But if you go overboard, it can cause excess levels of sodium in your body.

Yes, it has the same effect as at any other time of the day. It masks some of the bitter taste of dark roasted or stale coffee grounds, and negates the natural acidity of coffee, making it easier on your stomach at night if you have digestive issues.

So there you have it, folks. Adding baking soda to your coffee may not be the traditional way of making a cup of coffee, but if acidic coffee gives you an upset stomach or you want to make your coffee less bitter, why not experiment? Let me know your thoughts in a comment below!
