Brewing Espresso- Continued
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
your shot is coming out quickly, the grind needs to be adjusted finer, if your shot is coming out to slowly or
not at all, 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 a thick rich crema on top.
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.
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. A cleaning brush has also been included to clean the group screen and gasket.
Setting Coffee Brew Temperature
The Carola is equipped with a digital thermometer. The coffee brewing temperatures are adjusted with dip
switches located behind a trap door on the back of the machine.
To adjust the temperature, remove the trap door, make note of the original setting before adjusting. Please
ensure that the machine is unplugged directly from the wall to make sure there is no electrical current at all
running through the machine.The original setting should be 205 degrees Fahrenheit.
Please DO NOT adjust the boiler set point. This represented by the switches 7 and 8. These are to be left
in the “on” position. Please refer to the temperature chart to match the corresponding temperature to the
switch locations. Adjustments to the temperature are to be made while the machine is OFF!
