Why is weak acid like that so hard on the stomach? Stomach/gastric acid is way lower pH and is a strong acid. Orange juice is more acidic and less associated with stomach problems (but not unassociated).

  Assuming a 16oz cup of coffee, most people are not drinking ~2.5 liters (5 cups) of orange juice daily for extended periods.

    Five cups equals 2.5 liter? Then I assume you are American, where these huge quantities are more normal. And usually not that strong coffee either (on the contrary). The Spanish sometimes use 'CAFE' as an acronym: Caliente (hot), Amargo (bitter), Fuerte (strong) and Escaso (small amount).

      For reference, a Starbucks "grande" is 16oz. Starbucks has 6 sizes and the grande is the larger of the two middle sizes. A quick search of the first page of results on Amazon for "coffee mug" shows most of them are 16-20oz. Five, 16oz cups is 80oz, and there's 33oz in a liter. I'm not trying to disagree with you, just describing how I got my number, which is different than your reasonable implication.

  It seems to be less about the pH, per se, but about the effect that those particular chemicals have on the stomach. Some of them cause the stomach to produce more acidity. It may not even be the acidic chemicals themselves, but other coffee molecules that are extracted in roughly the same temperature/pressure regime. The mechanisms are hard to trace, since there are so many chemicals involved and the actual production of stomach acid so complicated. But you know what the doctor will say when you tell them that it hurts when you go like that.
