17 Recommendations for preparing the perfect
espresso
Preparing the perfect espresso is not only influenced by subjective factors,
but also by factors such as the coffee variety, coarseness, amount of ground
coffee, temperature, pre-infusion, flow, extraction duration, etc.
Until the right settings have been found, you may have to adjust and try out
different parameters. The following overview outlines common problems,
what causes them and how to solve them.
Problem
Espresso is not pouring
out, just dripping out of
the portafilter.
EN - 170
Cause
The coarseness of the
coffee used is too fine.
Brew pressure too low.
Ground coffee too densely
compacted.
Too much ground coffee.
Closed flow control.
Solution
Use more coarsely ground
coffee.
Increase the brew pres-
sure (see Chapter 5.2.4,
„Flow control").
Do not press the ground
coffee down as hard (see
Chapter 9.6, „Pouring
ground coffee into the
portafilter and pressing
(tamping)").
Use less ground coffee.
The marking in the filters
serves as a guide.
Open the flow control
(see Chapter 5.2.4, „Flow
control").
