Why Does My Coffee Taste Bitter or Sour? (And How to Fix It)
Short answer: bitter coffee is usually over-extracted (ground too fine, brewed too long or with water that's too hot). Sour coffee is usually under-extracted (ground too coarse, brewed too short or with water that's too cool). Change one thing at a time and taste again.
What "extraction" means
When hot water meets ground coffee, it pulls out flavor in stages. Bright, sour acids come out first, then sweetness and body, and bitter compounds last. Great coffee stops in the sweet middle. Taste tells you which side you missed.
If your coffee tastes bitter
Grind a little coarser. Smaller particles extract faster.
Shorten the brew. French press: 4 minutes, not 6. Espresso: aim for about 25–30 seconds.
Check the water temperature. 195–205°F is the sweet spot. Water straight off a rolling boil can scorch the grounds.
Don't leave it on the hot plate. Coffee sitting on a warmer for an hour turns bitter. Use a thermal carafe.
Clean your brewer. Old coffee oils build up and taste bitter and stale.
If your coffee tastes sour
Grind a little finer.
Brew a bit longer or use slightly hotter water.
Use enough coffee. A good starting ratio is about 2 tablespoons (10 g) of coffee per 6 oz of water.
Check freshness. Very fresh beans (roasted in the last day or two) can taste sharp. Let them rest a few days.
If it tastes weak and flat
Use more coffee, make sure the grind matches your brewer, and check the roast date. Beans more than a couple of months past roasting lose the oils that carry flavor.
