LOVE Double Diamond, it is the only coffee I drink in the mornings. It has a great flavor, isn't bitter in the least. I'd recommend this in a heartbeat to anyone who loves a very dark roast.
I've been buying the for about 4 years or more .I love it great taste .Great aroma my wife does not drink coffee and she love the aroma.I have found other coffees from Keurig but this is my 5 Star
