Coffee can trigger reflux symptoms for some people, while others tolerate it. NIDDK guidance includes coffee and caffeine among commonly reported triggers and recommends discussing foods and drinks that appear to worsen symptoms with a clinician. A general coffee article cannot determine the cause of an individual's discomfort.
CoffeeBox proposes darker roasting and cold brewing as gentler options, but those should not be presented as treatments or universal protection. Research distinguishes pH from total titratable acidity: one Scientific Reports study found similar pH values in matched hot and cold brews, despite other chemical differences. That does not establish how either preparation will affect a person's reflux.
A record of beverage type, portion, timing and symptoms may support a discussion about reducing or avoiding a suspected trigger. Seek medical advice for persistent problems rather than using roast or marketing labels as a diagnosis. Chest pain, trouble swallowing or signs of bleeding require prompt medical evaluation. This article provides context without prescribing a personal diet or reflux treatment.

A good question can make a better brew.
