The chemistry behind a better cup of coffee

What's Potassium Bicarbonate?

Potassium bicarbonate: a colorless, odorless, slightly alkaline compound, is known for various applications in cooking, wine-making, and health. What most people don't know is its magical effect on coffee.

Why add Potassium Bicarbonate to coffee?

Coffee contains naturally occurring acids that give it its characteristic flavor. However, these acids can make coffee quite harsh on the stomach, especially for those with acid reflux or similar conditions. Here is where potassium bicarbonate comes to the rescue.

When you add potassium bicarbonate to your coffee, a chemical reaction occurs: the potassium bicarbonate, being alkaline, neutralizes the excess acid in the coffee, balancing its pH.

1. Balancing the pH:

The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14, with 7 being neutral. Coffee usually has a pH of around 5, making it somewhat acidic. When we add an alkaline substance like potassium bicarbonate, it helps balance the pH, pushing it closer to the neutral range. Our internal tests have proven that just 2 drops reduces the acid content over 30%!

2. Reducing acidity

By neutralizing the acidity, potassium bicarbonate essentially "softens" the coffee. It lessens the acidic bite, which can often be perceived as bitterness, providing a smoother, richer flavor profile.

3. Stomach-friendly brew

This reduced acidity is not only pleasing to the palate but also gentler on the stomach. This makes it a great solution for those who love coffee but have sensitive stomachs or conditions like acid reflux.

How to add Potassium Bicarbonate to your coffee?

It's a straightforward process. Add a couple drops of chroma coffee drops to your cup of coffee after brewing. Remember, a little goes a long way. The result? A smoother, less acidic cup of coffee that's easier on the stomach.

Things to note

Although potassium bicarbonate is generally safe for use, everything should be used in moderation. Be sure to not exceed the recommended amount, as excess potassium can have health implications. If you have any health concerns or are on medication, it's always best to consult with your healthcare provider before making significant changes to your diet.


So next time you're brewing your coffee and wish to make it a bit gentler on your stomach, don't forget to add a few drops of chroma coffee drops. It's an easy way to balance the pH, reduce acidity, and enjoy the love of your life - your cup of coffee - without worrying about the aftermath.

And remember, coffee is more than a beverage; it's an experience. So, experiment and find out what works best for you. Enjoy your brew!
