Symptoms of This Issue

Not sure if this is your issue?

Get a personalized diagnosis

If beans were roasted less than 5 days ago, wait a few more days before using. Light roasts need 10-14 days, dark roasts 5-7 days.

Expected Result

More stable extraction, better flavor development, easier to dial in.

Adjust your grinder to produce coarser coffee particles. Make small adjustments (2-3 increments) and pull a test shot.

Expected Result

Extraction time should decrease by 3-5 seconds. Flavor should become less bitter and harsh.
