Why does my coffee taste bitter or sour?Updated 7 days ago

Almost always, this comes down to extraction, which is how much flavor gets pulled out of the grounds.

• Sour, sharp, or thin: under-extracted. Try a finer grind, hotter water, or a slightly longer brew time.
• Bitter, harsh, or dry: over-extracted. Try a coarser grind, slightly cooler water, or a shorter brew time.

A few other things to check: that your grind matches your brew method, that your equipment is clean (old oils can taste bitter), and that your water is fresh and filtered if possible. Change one thing at a time so you can tell what helped. Still not right? Contact us at https://larryscoffee.com/pages/contact and tell us how you brew, and we’ll help you dial it in.
