I do similar (2 beans).
Most don’t realize flavor is about the grind as well.
My morning cup from my Capresso EC100 espresso maker is best with 2 different grinds. @ 2 cups/day, 1 lb lasts about 2 weeks and tastes far superior to crappy, gun-hating brand-names at 1000% markup.
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.
