Over Extraction

An over extracted shot can be caused by :

• incorrect grind (too fine)
• packed in group handle too hard / tight
• group head not flushed out correctly / build up of coffee in the group head
• too much coffee in the group handle
• an incorrectly adjusted machine

You can tell a shot is over extracted if :

• It tastes bitter
• Extracts out too slowly and has a thin dark crème
• Has a burnt/black ring around the outside of the crème
