Coffee is one of the most popular beverages in the world, with millions of people starting their day with a steaming cup of joe. But for those who suffer from acid reflux, also known as gastroesophageal reflux disease (GERD), the question arises: Is coffee acidic or alkaline?

Coffee is almost always acidic at around 5 pH. While this makes it acidic it is not too acidic. For people with acid reflux some may notice it makes things worse and others may be fine with drinking it often, it often depends on each person individually if it’s the right choice for them or not.

In this article I will talk about how acidic coffee really is and what you need to know about drinking coffee if you have acid reflux.

What is the pH of Coffee?

To answer these questions, let’s first understand what pH is. pH is a measure of acidity or alkalinity on a scale from 0 to 14. A pH of 7 is considered neutral, while values below 7 are acidic and values above 7 are alkaline. When it comes to coffee, the pH level can vary depending on several factors such as the type of coffee beans used, the water used for brewing, and any additives like milk or sweeteners.

On average, coffee has a pH of around 5, which makes it slightly acidic. However, it’s important to note that the acidity of coffee can vary greatly depending on these factors. For example, dark roast coffee tends to be less acidic than light roast coffee. Similarly, adding milk to your coffee can help neutralize some of its acidity.

To put things into perspective, let’s compare the pH of coffee with other common beverages. Water has a neutral pH of 7, while tea typically falls in the range of 6-7. Soda, on the other hand, can be highly acidic with a pH as low as 2-3. So, while coffee is generally more acidic than water or tea, it’s not as acidic as some other beverages.

Is Coffee Good or Bad for Acid Reflux?

Now, let’s address the burning question: Is coffee good or bad for acid reflux? The answer is not straightforward. While coffee can trigger or worsen acid reflux symptoms in some individuals, others may be able to tolerate it without any issues. The response to coffee can vary from person to person, depending on several factors including genetics, lifestyle, diet, and medications.

There are a few possible mechanisms through which coffee can affect acid reflux. First, coffee can stimulate gastric acid secretion, which can lead to increased acidity in the stomach. Second, coffee has been found to relax the lower esophageal sphincter (LES), the muscle that prevents stomach acid from flowing back into the esophagus. Finally, coffee may irritate the lining of the esophagus, causing discomfort and exacerbating acid reflux symptoms.

So, what can you do if you want to enjoy your daily cup of coffee without aggravating your acid reflux? Here are some tips:

1. Opt for decaf coffee: Decaffeinated coffee contains less caffeine, which is known to stimulate gastric acid secretion. Switching to decaf may help reduce the risk of triggering acid reflux symptoms.

2. Choose brewed coffee over instant coffee: Instant coffee tends to be more acidic than brewed coffee. If possible, opt for freshly brewed coffee to minimize its acidity.

3. Avoid adding sweeteners: Sugar and artificial sweeteners can increase the acidity of your coffee and potentially worsen acid reflux symptoms. Try drinking your coffee black or with a splash of milk or alternative milk instead.

4. Limit your intake: Moderation is key. Limit your coffee consumption to 1-2 cups per day to minimize the risk of acid reflux flare-ups.

5. Try cold brew coffee: Cold brew coffee is known to be less acidic than hot brewed coffee. Consider giving it a try if you’re particularly sensitive to the acidity of regular coffee.

While these tips may help reduce the risk of acid reflux symptoms, it’s important to listen to your body and pay attention to how coffee affects you individually. If you find that coffee consistently triggers your acid reflux, it may be best to avoid it altogether.

How Does the pH of Coffee Affect Your Health?

Coffee is a beloved beverage enjoyed by millions of people around the world. It provides a much-needed energy boost and a comforting ritual to start the day. However, have you ever considered how the pH of coffee can impact your health?

Benefits and Drawbacks of Different pH Levels in Coffee

1. Acidic Coffee (pH 4-5):

   – Benefits: The acidity in coffee enhances its flavor and gives it a bright, vibrant taste. It can also provide a pleasant sensory experience for coffee lovers.

   – Drawbacks: Acidic coffee can irritate the stomach lining, leading to symptoms such as heartburn, indigestion, and acid reflux.

2. Less Acidic Coffee (pH 5.5-7):

   – Benefits: Less acidic coffee reduces the risk of stomach irritation and acid reflux. It may be a suitable option for individuals with sensitive stomachs or those prone to digestive issues.

   – Drawbacks: The flavor profile of less acidic coffee may be milder and less robust compared to its more acidic counterparts.

Alternatives to Acidic Coffee

If you experience digestive issues or want to reduce your coffee intake, there are alternatives you can consider:

1. Chicory Coffee: Chicory root is often used as a coffee substitute due to its similar flavor profile. It is naturally caffeine-free and has a less acidic nature, making it a gentler option for those with sensitive stomachs.

2. Herbal Tea: Instead of coffee, opt for herbal teas such as chamomile, ginger, or marshmallow root. These teas can soothe the digestive system and provide a comforting beverage without the acidity of coffee.

3. Cinnamon Drink: Create a caffeine-free alternative by mixing cinnamon powder with hot water or milk. Cinnamon has anti-inflammatory properties that can help soothe the digestive system.


Understanding the pH of coffee and its impact on your health is crucial, especially if you experience digestive issues or acid reflux. While coffee provides an enjoyable sensory experience and an energy boost, it’s important to be mindful of its acidity. Acidic coffee may exacerbate symptoms of acid reflux and irritate the stomach lining. Consider alternatives such as chicory coffee, herbal teas, or cinnamon drinks if you’re looking to reduce acidity in your beverage choices.

Remember, everyone’s tolerance to acidic foods and beverages may vary. If you have specific concerns about your digestive health, it’s always best to consult with a healthcare professional.
