My coffee maker is a 14 cup kitchen aid. My grinder is a capresso. I set the grinder between very fine and fine and put the highest time setting (10 whatever that unit means) that fills the little plastic bin with the right amount of ground coffee for the 14 cup maker.
Never know when Costco will end a particular coffee type. I liked the Guatemalan coffee by itself. But they stopped selling it.
That was my problem (beans I like disappearing).
I found a local company that consistently has their own bean mix that I mix in a nice dark french roast bean. Perfect balance for me.
In a consumer espresso machine, too fine a grind plugs the machine. Plus there’s a HUGE variable in flavor on the grind, finer the better. A careful balance of a 5 grind (Capresso as well, 1 = fine, 12 = most coarse) in the bottom to a 2.5 packed on top makes perfect flavor & function for me.
I discovered I prefer the flavor of espresso vs. very strong coffee and noted I get a whole day’s boost from only 2 cups; I just wish the quality of the machines was better for the price.
