There are countless reasons why so many of us reach for a cup of coffee every morning. In addition to helping you wake up and face the day, coffee can be healthy, not to mention tasty. But what happens when you love coffee but you can’t have it?

Unfortunately, coffee can be difficult for some people to drink, despite its benefits. The main reason why some can’t drink coffee is the high acidity, which can be hard on sensitive stomachs. For these coffee lovers, low-acid coffee is a great solution.

Low acid coffee is coffee that has been treated to raise its pH, making it less acidic. Low acid instant coffee is a powder that you mix directly with water to make low acid coffee. It’s a very convenient way to drink coffee that’s easier on your stomach.

What is acid in coffee?

Coffee is made from brewing coffee beans with water. Coffee beans are the roasted seeds of the coffee plant, which grow inside a type of fruit called coffee cherries. The coffee seeds contain many naturally occurring acids that contribute to the acidity level of brewed coffee.

The coffee seeds, also called green coffee, are then roasted before they can be used to make coffee. Lighter roasts are made from coffee seeds roasted for shorter periods or at lower temperatures. Dark roast coffee beans are roasted longer at up to 482°F.

All liquids have a pH level, a measure of how acidic or basic that liquid is. Very acidic liquids have a low pH (closer to 1), and very basic liquids have a high pH (closer to 14). Water has a neutral pH of 7.

Coffee naturally ranges between 4.5 and 5.5 on the pH scale. Low acid coffee is often treated to reduce its acid content, so its pH is usually around 6. Remember, the higher the number, the lower the amount of acid present. 

The acid level in coffee is different than its acidity. Acid levels refer to pH, while acidity refers to taste.

Coffee Roasts With Higher Acid Levels

The roasting process can affect how much acid is in coffee beans. In general, cold brews have less acid than traditionally prepared coffee. It’s also worth noting that very cheap coffee beans also tend to have high acidity. 

Here is the average pH level (acidity) of different popular coffee roasts:

  • Dark roast (also called French roast): 4.5-5.0
  • Medium roast: 5.0-5.5
  • Light roast (sometimes called a “breakfast blend”): 5.3-5.8

When reading this list, don’t forget that lower numbers mean higher acidity.

The decaffeination process can also change coffee’s acidity. Decaf coffee is generally less acidic than regular coffee, and it makes stomach cells secrete less acid during digestion compared to caffeinated coffee.

Who should avoid acidic coffee?

Some people need to avoid acidic coffee more than others. Most people tolerate the acids in coffee just fine, but others can be very sensitive to them.

For people who produce too much stomach acid or have a more sensitive gastrointestinal tract, the extra acid in coffee can cause digestive issues.

Here are some of the groups who should avoid highly acidic coffee:

  • People with acid reflux/GERD: If you have acid reflux, drinking coffee with reduced acid content can help ease your symptoms, particularly if you experience them after drinking coffee on an empty stomach. These patients may also benefit from drinking decaf coffee.
  • IBS patients: Coffee can exacerbate IBS symptoms by making you have to “go” and irritating the gastrointestinal tract.
  • People with thin tooth enamel: Acidic drinks like high acid coffee can wear away at the enamel of the teeth. It’s not a problem for most people, but drinking a low acid coffee can help protect your teeth if you have thin enamel.
  • Patients with bladder inflammation like interstitial cystitis: Patients with interstitial cystitis should avoid highly acidic foods and drinks in general, including high-acid coffee.

People who have these issues can benefit from drinking low acid coffee like Golden Ratio’s original gold coffee. It’s easier on the stomach and can be the perfect solution for coffee lovers who can’t tolerate high acid coffee.

Is instant coffee bad for acid reflux? Instant coffee is bad for acid reflux if you drink regular coffee. Low acid instant coffee is much easier on your stomach and is better for patients with acid reflux.

Low Acid Coffee Benefits

Low acid coffee has the same flavor profile as regular coffee, but it can be better for you in several ways. The benefits of low acid coffee include:

  • Better for your stomach: Regular coffee can irritate your stomach because it’s so acidic, particularly if you drink coffee on an empty stomach. Drinking low acid coffee lets you drink coffee without upsetting your stomach.
  • Better for your teeth: Drinks with lower acidity are better for your tooth enamel. If you’re going to drink coffee, low acid coffee is definitely the way to go.

What is the difference between regular coffee and low acid coffee? The difference between regular coffee and low acid coffee is low acid coffee has a higher pH. Low acid coffee is also generally easier on your stomach, particularly if you have digestive problems.

Does instant coffee cause heartburn? Instant coffee can cause heartburn if it’s not specifically low in acid. Drinking specially-formulated low acid instant coffees reduces your risk of developing heartburn after drinking coffee.

How To Neutralize Acid In Coffee

In addition to making low acid coffee, there are other ways to reduce or neutralize the acid in your coffee. You can reduce your coffee’s acidity by:

  • Cold brewing: Cold brew coffee has lower acidity than hot brewed coffee, so cold-brewing your coffee can help neutralize some of the acid.
  • Adding baking soda:Baking soda is a base, so adding it to coffee will neutralize some of the acid. Add a tiny amount — just a tiny pinch in a single cup of coffee — or you might not like the taste of your coffee.
  • Turning down the temperature: Hotter water extracts more acids from coffee beans. So, using cooler water to brew your coffee can help make your coffee less acidic, even if you’re not cold brewing.
  • Using a coarser grind: Coarse-ground coffee has less surface area than fine-ground coffee, making it harder for acids in the coffee beans to steep out.
  • Adding unsweetened almond milk: Almonds are alkaline, and unsweetened almond milk has a pH of around 6.5. Just skip the sweetened almond milk, which can actually make your low acid coffee more acidic.
