Can Coffee Cause Heartburn? Here’s What You Should Know

If that comforting cup of coffee is followed by a burning feeling in your chest, you’re not imagining things.

Coffee can cause or worsen heartburn — especially for people with acid sensitivity or GERD. But before you give up your morning ritual entirely, there’s good news: Not all coffee is equally triggering, and choosing the right kind can make a big difference.

Let’s explore what’s really happening in your body, who’s most affected, and how to enjoy coffee without the burn.

Why Does Coffee Cause Heartburn?

Heartburn, also known as acid reflux, occurs when stomach acid moves up into the esophagus. This can cause:

A burning sensation in the chest or throat

Bitter or sour taste in the mouth

Discomfort after meals

Coffee can contribute to this in a few ways:

It relaxes the lower esophageal sphincter (LES), allowing acid to escape upward

It’s naturally acidic, which can irritate the esophagus lining

It may stimulate excess stomach acid production, particularly in sensitive individuals

Not All Coffee Affects You the Same

The type of coffee you drink matters. Many people find that low acid coffee dramatically reduces their symptoms.

More likely to cause heartburn:

Light roasts (higher in acid)

Cheap, low-quality beans

Flavored or instant coffees with additives

Easier on the stomach:

Medium-dark or dark roasts

Certified organic coffee

Low acid coffee (like Java Planet’s Colombia or Guatemala)

Who’s Most at Risk for Coffee-Triggered Heartburn?

You’re more likely to experience coffee-related heartburn if you:

Have GERD (gastroesophageal reflux disease)

Have a hiatal hernia

Drink coffee on an empty stomach

Are sensitive to caffeine or acidic foods

Have poor digestion due to stress or diet

Tips to Reduce Coffee-Related Heartburn

If you’re not ready to quit coffee (and we don’t blame you), try these strategies:

1. Switch to Low-Acid Coffee

Low acid coffee is roasted and sourced to reduce acidity naturally. Java Planet offers a full line of low acid, organic roasts.

2. Don’t Drink on an Empty Stomach

Have food before your cup — this helps buffer acid and protect your stomach lining.

3. Choose Organic, Mold-Free Coffee

Contaminants like mold and mycotoxins can worsen gut irritation. Java Planet beans are tested and certified clean.

4. Watch Your Portion Size

Try one 8–10 oz cup instead of a large mug or multiple servings back-to-back.

5. Try Decaf or Half Caff

Caffeine can increase acid production. Java Planet offers Decaf Peru and Half Caff Peru — both low-acid and gentle on the gut.
