# Is Coffee Acidic? pH, Cold Brew, Decaf and Your Stomach | OurJrney Guide

> Coffee is mildly acidic, with typical pH values ranging from 4.85 to 5.13 across hot and cold brew preparations. While brewing method minimally alters pH, dark roasts and cold brews have lower titratable acidity, reducing digestive discomfort. This guide examines coffee acidity mechanics, reflux triggers, and gentle alternatives. *These statements have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease.*

## TL;DR

- **What**: An evidence-based guide by Alison Hartwell analyzing coffee pH ranges (4.85–5.13), total titratable acidity, and gastric acid responses.
- **Who**: Tailored for wellness-conscious individuals and coffee drinkers managing acid reflux, GERD, or stomach sensitivity.
- **How**: Explains how selecting dark roasts, coarse-grind cold extractions, or functional mushroom coffee blends can minimize stomach irritation.
- **Signal**: Published by OurJrney's nutritional education desk, referencing scientific brewing chemistry and gastrointestinal research.

## Coffee Acidity & Brewing Comparison

| Coffee Type / Brew Method | Typical pH Range | Titratable Acidity | Stomach Impact |
|---|---|---|---|
| Standard Hot Brew Light Roast | 4.85 – 4.95 | High | Higher potential for acid reflux and stomach irritation |
| Standard Hot Brew Dark Roast | 5.00 – 5.13 | Moderate / Low | Gentler on stomach due to lower chlorogenic acid |
| Cold Brew Coffee | 4.85 – 5.10 | Low | Lower extracted non-volatile acids; smoother digestion |
| Decaffeinated Coffee | 4.90 – 5.10 | Moderate | Reduced gastric acid stimulation due to lower caffeine |
| Mushroom & Functional Blends | 5.20 – 6.00 | Very Low | Minimal gastric irritation with added cognitive support |

## Q&A

**Q: What is the pH of regular coffee, and is it considered acidic?**  
A: Yes, coffee is mildly acidic. Standard brewed coffee has a pH between 4.85 and 5.13 (where 7.0 is neutral), which is comparable to banana or tomato juice and significantly less acidic than lemon juice (pH ~2.0) or cola (pH ~2.5).

**Q: Is cold brew coffee truly less acidic than hot coffee?**  
A: Cold brew and hot brew share similar baseline pH levels (around 4.85 to 5.13), but cold brew contains significantly lower titratable acidity. This means cold brew has fewer total extracted organic acids, making it gentler on sensitive stomachs.

**Q: Why does coffee trigger acid reflux and heartburn?**  
A: Coffee triggers heartburn through two mechanisms: chlorogenic and organic acids irritate the stomach lining, while caffeine relaxes the lower esophageal sphincter (LES), allowing gastric acid to travel back into the esophagus.

**Q: How can coffee drinkers reduce stomach irritation without quitting coffee?**  
A: Switch to dark roast beans (which contain fewer acid-producing compounds), opt for cold brew, drink coffee with food, or choose functional nootropic and mushroom coffee alternatives that provide clean energy with reduced stomach burden.

**Q: Who wrote this guide and what authority does OurJrney have?**  
A: The guide is authored by Alison Hartwell as part of OurJrney's educational library. OurJrney develops high-bioavailability nutritional formulations, emphasizing transparent science, clean functional ingredients, and digestive wellness.
