The way the espresso pours will tell
you everything.
1. Extraction Time
Extraction time is a good indicator of the
quality of the pour. The optimum time per
shot varies between types & freshness of
coffee beans. However, in general, the pour
time should be between 20-30 seconds for
both One & Two Cup shots.
2. Type of Extraction
• Optimum Extraction
A quality pour has a steady flow with a
consistency similar to that of warm honey.
The resulting crema is dark golden.
The sweetest flavors & oils have been
extracted creating a rich tasting espresso.
• Under Extraction
The pour is fast & light in color, the
resulting crema is thin with a creamy light
brown color which quickly dissipates. This
occurs when too little of the essential oils,
flavors & colors from the coffee grinds
have been extracted. This creates a sour
tasting espresso.
• Over Extraction
There may be no pour, or it may be slow
& drip throughout the entire pour. The
resulting crema is very dark. This occurs
when too much of the essential oils,
flavors & colors from the coffee grinds
have been extracted. This creates a bitter
tasting espresso.
3. Look for Color Change
The optimum shot contains 3 elements:
Heart: At the base - starts out dark brown.
Body: Blends with the heart - becomes a
rich caramel with reddish reflections.
Crema: The layer on top of the body -
dark golden.

* If using pre-ground coffee grinds, use Dual Wall Filter Baskets.
^ Ensure coffee beans or pre-ground grinds are fresh.
^^ Old coffee beans no matter the Grind Setting will have a fast extraction
and will produce an under extracted tasting espresso.
