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.

Espresso is not pouring
out, just dripping out of
the portafilter.
