Greetings!
I don't specifically select coffees that are low acid, but I buy high quality beans, grown by small producers who care, and roast them for maximum sweetness and balance of flavor. To me, the perceived acidity in the cup is low, but I've never tested it to determine actual acid levels or types.
Anecdotally, I have a number of friends who have had trouble with other coffee but feel good after drinking SOUND COFFEE. Everyone is different, of course.
