How to Tell If a “Low-Acid” Coffee Claim Is Real — and What to Do If It’s Not. Consumers and competitors rely on accurate product claims. But when companies market coffee as “low-acid,” “stomach-friendly,” or “caffeinated” without transparent evidence, those claims can be misleading — and in some cases legally actionable.
⚠️ The Independent Test Results: A 2024 peer-reviewed study by NC A&T State University tested 7 brands claiming to be “low acid.” 6 of 7 failed — their pH was no different from regular commercial coffee. Only Puroast passed, measuring at pH 5.74+ — above the verified 5.5 threshold. (Wikipedia: Low-acid coffee)
