  1. Any coffee can make anyone’s stomach irritated. The reason is the acidity. Some coffees are more acidic than others. Starbucks happens to have different coffees of all levels of acidity. Another thing that can irritate your stomach is MILK! Don’t mistake that dairy you shouldn’t be drinking for the irritation your body is having 😉

  2. Because Starbucks roast beans standard is too dark, it is what most coffee snobs call “charcoal roast”, it will definitely upset the stomach.
    Why they do this? Because it’s easy to achieve uniformity, thus save time, minimize difficulties, and dark roast will easily masks funny tastes from defective beans, related to this, one of my roaster friend also said that defective beans will carry the risk of bacterial contamination, so it is reasonable to burn the beans as dark as possible.
    In short, they’re cutting corners everywhere in the name of efficiency. It is widely suspected that Starbucks is very lenient on their beans quality control. One quoran said he bought a can and found so many defective beans, now, that is not just disappointing, but dangerous.
    But Starbucks are moving to a good direction nowadays, following the third wave coffee trend, they introduce blonde roast (which is basically “light-medium” roast, there a lot of different names used for roasting levels), establishing Starbucks Reserve, better beans, etc.
    In most cases, people will have an upset stomach because the coffee beans are either defective or improperly roasted, or the coffee is not brewed properly.

  3. It depends on which drink, but I have found the super sugary ones really screw with me. But, then again, my regular sugar intake is pretty low. I know some people have a sensitivity to caffeine and their drip coffee is pretty intense.

  4. According to this article http://www.webmd.com/digestive-disorders/news/20100322/brewing-gentler-java, the elements of coffee that may contribute to stomach irritation include:

    …caffeine, catechols, and chemical-substances called N-alkanoly-5-hydroxtryptamides stimulate molecular mechanisms of stomach acid secretion in human stomach cells.

    I don’t see how that is unique to Starbucks (like they’re adding those unpronounceable ingredients in there to irritate the stomachs of their customers).
    Maybe less of it is the answer (3/4 coffee + 1/4 hot water).

  5. The drip machines often sit around longer than they are supposed to (between 45 minutes to 1 hour) and this causes the taste to be rather acerbic. The machines, at least to the ones dispersed to California Starbucks, do not have timers on them and it’s the responsibility of the employees to attach separate timers and brew a new batch of drip coffee every 45 minutes. Most employees don’t do this, and if you don’t see a timer in sight – it’s likely that it will be one acidic cup of coffee since it’s probably being used until it runs out.
