We live just a few miles from a Black Rifle Coffee Company roasting facility, so it's nice to go into the outpost store there and pick up fresh-roasted coffee (they also throw out tons of chaff, left over from grinding, which is fantastic for garden plants that love acidic soil!). We had some and the coffee-snob Darling Bride almost couldn't drink it, it was so relatively weak to our go-to. So, it's back to our go-to: Costco's Kirkland Signature French Roast beans. Super dark, rich, and I have the grinder set on "5", which is barely coarser than an espresso grind. Being Navy people, we wake up in the morning with way too much blood in our caffeine system and need a good liquid jumpstart.
If you're close to a BRCC facility, just go there with a pickup truck and ask for a bag of chaff. They'll probably be glad to hoist one with a forklift and put it in the bed. A bag is 5 five cubed, weatherproof and weighs about 150-200 pounds. It will last you a LONG time.
