Tamping
-
After filling the basket with coffee then use your tamper to apply 30lbs of
pressure evenly on the coffee bed. Then without applying any pressure lightly twist the
tamper on the bed of coffee to “polish” the loose grounds on top. Then lock the portafilter
firmly into the group head and then press either shot button. It is very important to tamp
consistently with the same pressure each time or your shot quality and timing will vary.
The grind
-
Adjust your grind so that when you activate the pump, the flow of coffee coming
out of the portafilter spout looks like the tapered tail of a mouse. It should take
approximately 25 seconds for a 2 oz. double shot. If it is coming out quicker then the grind
needs to be adjusted finer, if it is coming out slower or not at all then the grind should be
adjusted coarser. The grind particle size should look in between powder and salt. Not as
fine as powder, but not as coarse as salt. Getting the right grind is crucial to making
delicious espresso with thick rich crema.
Consistency
-
The quantity of ground coffee and tamping pressure should always be the
same. Using more or less coffee or tamping lighter or harder will greatly affect the outcome
and timing of the shot. If the shots are not coming out properly then the only variable that
should be changed is the grind.
Cooling Flush
-
A cooling flush is not needed on a dual boiler machine and may actually
ruin the temperature stability of the shot and is not recommended for optimal performance.
Cleaning Tip:
Get into the habit of disposing of the spent grounds immediately after brewing
espresso. After disposing of the grounds, return the portafilter to the group head and raise
the brew lever for a few seconds to rinse away excess oils and loose grounds. By regularly
following this procedure, you will greatly reduce the tar-like buildup on the shower screen
that occurs if you allow coffee oils to dry and bake on the hot group.
