A while back, SO bought me a Keurig as a gift. We went through many types of coffees, bought the cups so we could grind our own coffee for the Keurig. I could never find combination that gave me satisfactory cup.
Consequently, I switched back to my Cuisinart coffee machine. I buy Starbucks whole bean French Roast at Costco and grind my own. Much better.
SO continues to use the Keurig for her coffee. Usually Starbucks House Blend, Gevalia Cappuccino or some kind of chai.
