Medium dark roasted Sumatran, or Java Coffees will be very low in acidity e.g. Java Blawan Estate, any Sumatran, Old Brown Java, Monsooned Malabar

Avoid medium and light roasted coffees, Kenyans, Mexicans, Some/Most Brazils, Nicaraguans.

But I agree with Mark, unless we know what the problem is, it's hard to recommend anything.

e.g. I suffer from GERD, but coffee is not the problem, neither is acidic foods, although the some doctor might spout that sort of bullshine. For me it's wheats and wholegrains that cause a problem. Depending on your diagnosis, acid coffee may not really be your problem. The stomach is immensely acidic, and you would have to take proton pump inhibitors (e.g. Lansoprozole or Omeprazole etc..) in a reasonable dose to suppress all acidity. If your not taking those, the acid in your food has feck all difference to the acidity in the stomach.

P.S. I should have added that after cutting out the (non acidic) foods that cause GERD, I do drink 8-10 doubles a day and it causes me no problem whatsoever!

Only way to really know for sure would be to make u a batch & test it with a litmus strip.

bear in mind that the stomach has a Ph of 1.5 to 3, with a gastric fluid volume varying between say 60 ml to 400 ml, probably averaging around 250 ml. The Ph scale is logarithmic http://chemistry.elmhurst.edu/vchembook/184ph.html

Coffee has a ph similar to milk around 6 to 6.5....so were really a very long way from affecting the square root of feck all as far as ph is concerned.

I'm not confusing acidity with acid- I said in my original post low acid coffee- exactly what is sold in the packets on the link. I'm not a coffee connoseur I just hoped someone had some information on low-acid coffees that I can only seem to see available in the US. I know there are some beans that are lower in acid than others but if you have a medical condition even lower acid beans may cause issues. You don't really need to know what my issue is to help me, but I have an irritated bladder so coffee, alcohol etc is out. Even decaf coffee can cause pain. BUT the low-acid coffees on sale in the US don't cause pain/issues as there are many reviews from people with bladder issues, stomach ulcers, heartburn etc and they can drink this coffee fine but not normal coffee. I hope this clarifies what I'm talking about.

Not really and you have not shared what the condition is...so I guess you're going to have to import the coffees that you like, preground, from the US. Or start drinking tea...oops wait tea is acidic as well? Perhaps a fruit infusion instead.

I thought it was more like 5.0-5.5?

I have a ph meter, last time I tested it was in the range 6-6.5. I would test again, but the thing is one of those hydrated glass bulb units, have not used it for years now. I suppose I could see if I can revive it and do some more testing.
