Trouble shooting
• The right coarseness of the coffee/espresso bean is important. If the coarseness is finer, more flavour
will be extracted. If the setting is too fine, the contact time of hot water will be too long and too
many bittern will be extracted. And also the crema clears away again.
• Varying the compacting pressure of the powder in the portafilter shows similar effects as varying the
coarseness.
Taste is not okay?
Finding
Possible cause
bitter taste
beans ground too fine, beans compressed too much, percolation is too long, too
much powder, too much pressure
sour taste
no suitable water, water is too soft, brewing temperature is too low, beans
ground too coarse, roasting is too light, percolation is too short, wrong coffee
type (coffee roasting instead of espresso roasting)
off-flavour
bad bean quality, beans are stored too long, chlorinated water, wrong espresso
type
not enough flavour
not enough powder, coffee is too old, powder is too coarse, powder is not
compressed enough, too much water
