ADJUSTMENTS
Adjustable Variables Used to Create A Perfect Shot of Espresso Topped with Crema
:
The primary 2 variables that you mostly will adjust to achieve your ideal double shot espresso pour time will
be the coffee particle size and the dosage targets.
Variables
1. Coffee Particle Size: Adjustable
2. Espresso & Water Dosage: Adjustable (Target 12 grams espresso, 60 ML water for double shot)
3. Dry Tamp Percentage: Factory Default Setting 60 - Adjustable 60-100
4. Espresso Water Temperature: Factory Default Setting 215° F. Adjustable 190°-218°
Brew/Pour Time Target
• 17-23 Seconds Brew Time for Double Shot Espresso
Once the double shot has been calibrated, the grinder coarseness adjustment is complete. The only
adjustment you will need to perform is setting the espresso & water dosage for a single shot espresso.
Single Shot
: 7 grams espresso, 30 ML water
NOTE:
The brew/pour time will be what it is once the single shot dosage parameters are set.
Procedure Setting the Coffee Grinder Grind Setting
:
Do Not
change the grind particle size significantly, change coffee coarseness in 1 click (knob) or 1 hashmark
(adjustment screw with lock nut) increments, as it will change the grind rate, thus the amount of coffee
ground and brew/pour time.
Step 1
: First, ensure espresso beans are in the hopper. Open the door, and slide the espresso brew group
lock to the left to unlock the brew group. Tip the top of the brew group head towards the front of the machine
to disengage from the espresso drive, then remove brew group from the drive.
Step 2
: Enter program mode and scroll to “Strength Adjust” menu. Enter and scroll to “Test LG Grind Time”
menu. Place cup under grinder chute to catch coffee grounds during grind adjustment. Press the espresso
button to start the grinder dispense timer, adjust the grinder adjustment screw while the grinder is operating
until grind particle size is desired or matches a desired grind sample.
Step 3
: After setting the grind particle size, tare cup on weigh scale and then place cup under grinder chute
and press the espresso button to start the grinder dispense timer, weigh the dispensed grounds. The target is
12 grams for a double shot espresso. Adjust the grind time and keep repeating the grind throw test until 12
grams is achieved.
Step 4
: Next, enter program mode and scroll to “Set Espresso Shots” menu. Select menu and scroll thru sub
menus until “LG Brew Volume” is displayed. Ensure the tic number is set at 190/default.
NOTE
: 3.0 tics = 1.0 mil, Default 190 tics divide by 3.0 = 63.33 mils. This is your brew volume target
63.33mils for a double shot. The extra 3.33 mils most likely will be absorbed in the espresso puck resulting
around 60 mils of finished product/double shot.
Step 5
: Reinstall the brew group, return switch to the “Normal” position and close door. Make a large
espresso to see if your brew/pour time is within the 17-23 seconds.
NOTE:
Anytime you make an adjustment to the coffee coarseness and grind time, a shot must be discarded
between adjustments. If the pour is too slow or too fast, repeat all steps until you are within the 17-23
seconds brew time.
NOTE
: Steps 1 thru 3 will take some back and forth adjustments to achieve the target brew time. You should
end up with a dark color espresso, topped with a tan colored foam called crema. The crema may also have a
marble like appearance.
