FEATURES OF YOUR BREVILLE PROFESSIONAL 800 COLLECTION™ Fresca Espresso Machina™ (continued)

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.

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.

Commercial Style Steam Wand

The swivel-action steam wand with stainless steel frothing attachment, easily adjusts to the perfect position for texturing milk. The wand has a commercial style 360° ball joint.
