We have coffees with low acidity and lower acid taste. I'm not sure where they rank in terms of ph, though.
Unfortunately I cant answer this from personal experience. However, all caffeine whether high or low has acidic content. Trader Joes is known for carrying eco sustainable products. So the best bet is to call the store and find out directly from a worker/ manager. Be sure to balance out acidic foods with alkaline foods and beverages.
They have several types of coffee there i believe they might have a low acid based one not definite on the brand names of coffee if i were you i would check it out they have so much food i think you will be happy when you go you will find something there that will peek your interest.
Sorry, I do not use coffee therefore never checked. I would go out on a limb and say perhaps the decaffeinated version would be less acidic. I'm sure you can call to find out.
Don't know
Honestly I'm not sure
