EXTRACTING ESPRESSO
• As a guide the espresso will start to flow after 8–10 seconds (infusion time) and should be the

• If the espresso starts to flow after less than 6 seconds, you have either under dosed the filter
basket and /or the grind is too coarse. This is an UNDER EXTRACTED shot.
• If the espresso starts to drip but doesn't flow after 15 seconds, the grind is too fine. This is an
OVER EXTRACTED shot.
CORRECT EXTRACTION
• Flow starts after 8-12 secs
• Flow slow like warm honey
• Crema is golden brown with a fine
mousse texture
• Espresso is dark brown
