EXTRACTING ESPRESSO
• As a guide the espresso will start to flow after 8–12 seconds (infusion time) and should be the
consistency of dripping honey.
• If the espresso starts to flow after less than 7 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 12 seconds, the grind is too fine. This is an OVER
EXTRACTED shot.
