What Is Acid in Coffee?

You may be wondering what we mean when we say acidic coffee. Like with other foods and beverages, coffee contains several different organic acids. Citric, tartaric, malic, acetic, and quinic acids are all found in your favorite brews. Roasting coffee beans changes these acids. In some instances, you may see higher levels and in others, the acid is completely roasted away.

When people talk about acidic coffee, they mean the specific tastes the acids provide the coffee beans. Of course, citric acid, which mostly tastes like oranges, offers your coffee a hint of citrus flavor. Malic acid tastes fruity while tartaric tastes like wine. Too much acetic acid and your coffee will taste very similar to vinegar.

The Disadvantages of Acidic Coffee

While certain acids can help improve the taste of your favorite coffees, they can also be a nuisance to the human body. Those who choose to switch from regular to decaf coffee due to the health benefits are constantly wondering if those benefits include help against the effects of acid.

Acids vs Your Teeth

Anyone who drinks coffee has heard about the effects it can have on your teeth. Some people have staining while others have more severe issues with their tooth’s enamel. This is thanks to the acids found in your favorite brews.

Acids in coffees have been known to demineralize your teeth. Unfortunately, this makes them more vulnerable to more acid corrosion down the road. Certain acids found in coffee can also make your mouth make its own acids. When this happens, there’s a full-blown acid party inside your mouth damaging your teeth.

You may be wondering if switching to decaf can help with the issues coffee causes your teeth. Unfortunately, as of now, it really can’t do much. Yes, decaf is better overall for your health, but the acids are still there and your teeth will be affected in some way.

Acids & Your Stomach

Many coffee drinkers find themselves suffering from issues with their stomachs. This is not unusual and has been one of the main reasons coffee drinkers have reluctantly given up their favorite drinks over the years.

The main acid-causing issue with your stomach is quinic. When present at modest levels, this acid provides a smooth finish to coffee and a nice flavor. When found in excess, this acid is known to cause acid reflux and upset stomach. Dark roast coffees or those that have been left sitting in the pot are often the biggest culprits of high levels of quinic acid.

This is where decaf coffee comes into play. While you won’t be ridding yourself of all acid levels, decaf coffee is known to reduce acid reflux for coffee drinkers. Keep in mind, this doesn’t mean you won’t experience an upset stomach or other issues acidic coffee causes. It simply means decaf coffee may help you avoid heartburn and other symptoms of acid reflux while you enjoy your morning joe.

Cold Brew May Be Your Answer

If you’re worried about the effects of acid in your coffee, there is a way to avoid it and still get the flavors you love. Switch to cold brew.

Cold brew coffee may not be a favorite for all coffee drinkers but the process used to make it does help lower acid levels in the beans. When the coffee beans are soaked in water 24-hours before use, certain compounds cannot properly dissolve. This helps avoid an overly acidic cup of coffee when you drink it.

You may not be the biggest fan of cold brew coffee, but for a less acidic taste, consider combining this method with decaf coffee and you may have a real winner on your hands. You’d be hard-pressed not to notice all the health benefits of choosing this drink for your enjoyment.
