None of them are really practical at home. And do you think it could be due to high acidity of certain coffees instead of the caffeine? You could try darker roasted coffees or some low acid beans (from Brazil or something) to rule that out.

I agree with KennyH on the above. Caffeine wouldn't cause heartburn, as it is actually weakly basic - that is, the opposite of acidic, and it's an excess of acids that leads to heartburn. Decaffeination methods are all chemical treatments of coffee, which require either some pretty nasty solvents or stuff that's less harmful but even harder to obtain (like dry ice, which is solid carbon dioxide). To sum up - try getting coffee that's less acidic, and if you want decaf - leave it for the food industry to provide you with it ;-)

GERD, reflux, or heartburn may be made worse by substances that are not necessarily acidic in themselves.  There is plenty of acid in the stomach already.  Some lower the tone of the muscle between the esophagus and stomach and allow more reflux.  Coffee studies are not conclusive and many with GERD learn their triggers and avoid them, caffeine being one.  Summary of a few of the internet articles.

Yeah, caffeine can exacerbate heartburn, but I was just thinking it'd be better if he tried less acidic kinds of coffee first before concluding that caffeine was the culprit.

Although caffeine can reduce the gastric sphincter tone and potentially increase indigestion or reflux, one major effect is in the coffee itself, and not caffeine.

When coffee, regular or decaffeinated, is instilled in the stomach, the gastrin level increases, which in turn increases hydrochloric acid secretion and the associated gastrointestinal symptoms. When only caffeine is instilled, it actually does not increase gastrin secretion significantly, if at all.

There are currently over 1000 compounds categorized in coffee, and probably more.  Caffeine itself most likely plays a minor role in indigestion.

Hello ccup,

Actually there are so many ways on how to decaffeinate coffee beans but are all basically similar. First, they swell the green beans using water or steam, and then using a solvent they extract the caffeine. Water strips the caffeine away and then steamed to remove the solvent residue and dried.

I agree with KennyH you should at least try other coffee and the less acidic ones. Hope this help 
