Under extraction range: When the needle has not reached the Espresso range, this indicates
the ideal pressure range has not been achieved.
This happens when the water flows too fast through the ground coffee, resulting in a watery,
flavorless shot with little to no crema.
This occurs because of 3 main reasons:
� The coffee ground is too coarse
� Under tamping
� Not enough coffee in the Filter Basket
Over extraction range: When the needle has surpassed the Espresso range, this indicates
the ideal pressure range has been exceeded.
This happens when the water flows too slowly through the ground coffee, resulting in a small,
dark and bitter Espresso shot with uneven crema.
This occurs because of 3 main reasons:
� The coffee ground is too fine
� Over tamping
� Too much coffee in the Filter Basket
