Yes, you can drink coffee if you have acid reflux, but it’s best to limit intake and choose low-acid options to minimize symptoms.
If you suffer from acid reflux, you’ve likely wondered whether coffee is off-limits. The relationship between coffee and acid reflux is complex, with scientific evidence showing mixed results. While some people experience worsened symptoms, others tolerate coffee just fine. This guide explores how to enjoy coffee without triggering reflux.
How Coffee Affects Acid Reflux
Coffee contains several compounds that may impact digestion:
- Caffeine may relax the lower esophageal sphincter
- Chlorogenic acids can increase stomach acid production
- Natural acids (pH 4.85-5.13) may irritate some people
A 2014 study in Molecular Nutrition & Food Research found dark roast coffee caused less stomach acid production than medium roast. The key was its higher N-methylpyridinium (NMP) content.
Cold Brew vs Hot Coffee
Cold brew coffee typically has lower acidity (pH 6.31) compared to hot brew (pH 4.85-5.13). The cold extraction process results in 67% less chlorogenic acid, potentially making it gentler on digestion.
6 Ways to Enjoy Coffee With Acid Reflux
1. Choose Low-Acid Coffee Beans
Look for beans processed to reduce acidity:
| Type | Acidity Level |
|---|---|
| Dark roast | Low |
| Brazilian beans | Low |
| Sumatran beans | Medium-low |
2. Try Different Brew Methods
Brewing technique affects acidity:
- Cold brew (least acidic)
- French press
- Pour-over
- Espresso (most acidic)
For a gentler option, consider a self-grinding coffee maker that preserves bean oils.
3. Add Milk or Plant-Based Creamer
A 2019 study found milk proteins bind to chlorogenic acids, potentially reducing acid production. However, full-fat dairy may worsen reflux for some.
4. Limit Portion Sizes
Stick to 8-12 oz servings rather than large mugs. Smaller amounts are less likely to trigger symptoms.
5. Time It Right
Avoid coffee:
- On an empty stomach
- Within 3 hours of bedtime
- During flare-ups
6. Consider Alternatives
When symptoms are severe, try:
- Chicory root coffee
- Dandelion root tea
- Matcha (lower acidity)

When to Avoid Coffee Completely
Consider eliminating coffee if you experience:
- Frequent heartburn after drinking
- Regurgitation of acid
- Worsening nighttime symptoms
- No improvement with low-acid options
According to Medical News Today, about 30% of GERD patients report coffee as a trigger.
Other Lifestyle Changes That Help
Combine coffee modifications with these reflux-reducing habits:
- Eat smaller, more frequent meals
- Maintain a healthy weight
- Elevate your head while sleeping
- Avoid tight clothing
- Quit smoking
As noted in Verywell Health, lifestyle changes often provide more relief than dietary modifications alone.
The Bottom Line
Many people with acid reflux can enjoy coffee in moderation by choosing low-acid varieties, adjusting brew methods, and timing consumption carefully. Pay attention to your body’s signals and work with a healthcare provider to develop a personalized approach.
