My coffee machine starts with whole beans. I've found one and only one coffee that works. Allegro brand Organic French Roast. I mix regular and decaf beans. I get it at Whole Foods or Amazon. I wait until they put it on sale, usually $2-3 off and then buy out the store. Our freezer in the basement is full of coffee.
The coffee machine makes an Americano. I set it to make two in one cup. I drink it black. Of all the things I consume in a day, my morning cup of coffee is the highlight. (Especially if it's in the sloth mug.)
