Double Donut Coffee brand, espresso roast. $29.00 for an 80 pack on Amazon. I have been buying for years. I subscribe for an additional 15% off. The price keeps rising and the amount in the k cup was reduced once without a change in flavor. It’s a good brew at an exceptionally low price. If you’re going to be a heretic, you might as well save a few bucks. I make it with the strong button depressed.
