We had a long thread on the best coffee. We all agreed that it’s wherever you can find it. Could be a from a mom and pop, at work, a machine, gas station, or McD’s. Or any other name brand. Just has to be good, Helps if it’s cheap.
Love my Keurig. One thing I found from using 2 pods is that if I mix two different pods, a Starbucks Tiramisu pod with a cheap brand, it can turn a so so cup of coffee to a good one.
