III. Espresso Shot Issues Q&A ❓
Sourness often indicates under-extraction.
Solution: Adjust the grind finer and increase the extraction time.
Bitterness is a sign of over-extraction.
Solution: Adjust the grind coarser and decrease the extraction time.
Fast flow suggests coarse grind or low coffee dose.
Solution: Use a finer grind or increase the coffee dose in the portafilter.
Slow flow indicates a fine grind or high coffee dose.
Solution: Use a coarser grind or decrease the coffee dose.
Weak flavor results from under-extraction.
Solution: Ensure proper tamping pressure and adjust the grind finer.
Overpowering taste comes from over-extraction.
Solution: Check the tamp pressure and adjust the grind coarser.
IV. Perfecting the Espresso Shot Pull ⏳
- Preparing the Portafilter
- Ensure the portafilter is clean and dry before dosing coffee grounds.
- Distribute the grounds evenly, and use the tamper to create a level surface.
- The Brewing Process
- Start the extraction immediately after tamping to prevent channeling.
- Aim for a total extraction time of 25-30 seconds for a standard double shot.
- Observe and Adjust
- Pay attention to the espresso’s color, texture, and flow during extraction.
- Make small adjustments to the grind size and dosage based on your observations.
