TIPS FOR GRINDING, TAMPING & BREWING
Dialing In
Setting up your Perfect Brew Máxima Espresso
Maker to make perfect Espresso is something
that you are unlikely to get right first time. Baristas
perform an operation called 'dialling in' and this is
performed whenever a variable is changed, such
as a new bag of beans are used, and is often
performed at the start of each day.
The dialling in process is not complicated, however
it may take a number of iterations to identify your
optimum grind setting and your perfect espresso.
There are 3 key variables to control when dialling in
your machine:
1. Amount of coffee grounds - Your Perfect Brew
Máxima Espresso Maker will ensure this
remains consistent espresso to espresso as it
will automatically doses the correct amount of
grounds for the selected shot size.
2. Tamp force – best results can be achieved using
a manual tamp, but a little practise is necessary
to apply the same force every time. Try using
your kitchen scales, pushing down to reliably
apply 10-15kg force.
3. Coffee grind size – this is the variable we will
adjust when 'dialling in'.
Make your espresso as shown in the pictorial guide,
starting with a grind size of 15.
When extracting you should aim for an extraction
time between 25-30s for a double shot.
If the extraction takes longer the grind is too fine. If
the extraction is shorter then the grind is too coarse.
Adjust the grind size up or down as needed.

When you brew an espresso in 25-30s, then you
have identified the correct grinder setting for specific
machine and beans.

Espresso dialling in optimisation examples
Example 1. Grinding a double espresso. The
extraction finishes dispensing in 15s. The water
is flowing through the grinds too easily, and the
coffee will be under extracted and light in colour.
- Reduce the grind size to a finer setting, and
tamp with the same pressure. When the coffee
dispenses in 25- 30s the espresso will be
perfectly extracted.
Example 2. Grinding a double espresso. The
extraction finishes dispensing in 45s. The water
is struggling to pass through the grounds, and
coffee drips slowly from the portafilter. The
coffee will be over extracted and very dark in
colour.
- Increase the grind size to a coarser setting and
tamp with the same pressure. When the coffee
dispenses in 25 - 30s the espresso will be
perfectly extracted.
