The sourness often stems from under-extracted acids, while bitterness comes from over-extracted compounds. But when both hit at once? That’s a sign the coffee’s not playing fair.

Meanwhile, bitterness arises from over-extracted compounds like chlorogenic acids and caffeine. But when a cup feels like it’s juggling both, it’s usually uneven extraction. Imagine a pour-over where water hits…
