FEATURES OF YOUR BREVILLE PROFESSIONAL 800 COLLECTION™ FRESCA ESPRESSO MACHINA™ (continued)
OVER ExTRACTED ZONE
The gauge needle when positioned within
the upper zone during pouring will indicate
that the espresso will be produced with too
much pressure resulting in an ‘over extracted’
espresso. This occurs when the water flow
through the ground coffee in the filter is too
slow. As a result the coffee will be very dark
and bitter, with a mottled and uneven crema on
top. Possible other causes for over extraction
are: ground coffee is too fine and/or too much
ground coffee in filter and/or over tamping.
UNDER ExTRACTED ZONE
The gauge needle when positioned within the
lower zone during pouring indicates that the
espresso will be produced with insufficient
pressure resulting in an ‘under extracted’
espresso. This occurs when the water flow
through the ground coffee in the filter is too
fast. As a result the optimal flavour will not be
extracted and the coffee will be watery and lack
thick crema on the top. Possible other causes
for under extraction are: coffee grind is too
coarse and/or insufficient coffee in filter and/or
under tamping.
