How to Use the Espresso Extraction Time Guide
A good espresso shot needs both its yield-to-dose ratio and extraction time within a healthy range. The common standard is a 1:2 to 1:2.5 ratio and a 25-30 second extraction time. This guide takes your dose, yield, and actual extraction time, then diagnoses whether your shot is running normally, too fast, or too slow. The basic rule is: grind finer if it's too fast, coarser if it's too slow. Instead of guessing by feel every time, checking against real numbers lets you dial in your grinder much faster and pull a consistent shot every time.
Diagnosis Reference
| Status | Criteria | Adjustment |
|---|---|---|
| Too fast | Under 22 sec | Grind finer |
| Normal | 25-30 sec, ratio 1:1.8-2.6 | Keep current setting |
| Too slow | Over 32 sec | Grind coarser |
Frequently Asked Questions
