PSA: My 'good' coffee was just bitter water for a decade
I was making a pot for my sister when she visited last fall, and she asked why my kettle was whistling. I had always boiled the water full blast. She said, 'You know that's way too hot for that light roast, right?' I'd been burning the beans for years without a clue. I got a simple thermometer and started brewing at 205 degrees, and the difference was crazy. Has anyone else had a basic thing they were messing up for ages?
