My brother-in-law said to never buy pre-ground coffee from the grocery store
He told me this about a year ago, and I thought he was just being snobby. I kept buying the big can of ground coffee for my drip machine. Then, for my birthday, he got me a cheap blade grinder and a bag of whole beans from a local roaster in Portland. The difference was insane. The coffee tasted so much brighter and less bitter. I feel like I wasted a whole year on stale coffee. Has anyone else made the switch and been totally surprised?
Seriously though, that flavor gets too specific. My buddy can now taste "hints of regret and a mortgage payment" in his morning cup. It's a slippery slope.
Call that pour-over "regret-roast" with a side of existential dread. Your buddy needs to switch to instant and save his taste buds the trouble. Burr grinders just unlock flavors you didn't ask for.
