1. Coffee beans
For optimum flavour and extraction:
- Buy freshly roasted coffee beans in small
250g batches to reduce the storage time.
- Use within two weeks of opening.
- Store coffee beans in a dry, airtight
container. Place in a cool dark cupboard.
2. Filter baskets
• Single wall filter baskets
These work with freshly ground coffee
grinds.
\• Dual wall filter baskets
These work best with pre-ground coffee
grinds, but can also be used for freshly
ground coffee grinds.
3. Grind dosage and tamp force
For best results, the amount of coffee
grinds dosed should remain consistent.
Evenly tamp coffee grinds to the level
indicated, with firm force 10-15kg.
The way the espresso pours will tell
you everything.
1. Extraction time
Extraction pour time is a good indicator of
the quality of the pour. The optimum time
per shot varies between types and freshness
of coffee beans. In general, the pour time
should be between 20-30 seconds for both 1
CUP and 2 CUP shots.
2. Espresso pressure gauge
The pressure gauge shows you how much
pressure is applied to your coffee during an
extraction.
• Optimum Extraction
When the espresso pressure gauge needle
is positioned anywhere within the OPTIMUM
zone during extraction, this indicates
the espresso has been extracted at the
optimum pressure.
A quality pour has a steady flow with a
consistency similar to that of warm honey.
The resulting crema is dark golden.
The sweetest flavours and oils have been
extracted creating a rich tasting espresso.
• Under Extraction
When the espresso pressure gauge needle
is positioned in the lower zone during an
extraction, this indicates the espresso has
been extracted with insufficient pressure.

Tips for coffee and tamping

Important: Old coffee beans will have a
fast extraction and will produce an under
extracted tasting espresso. The espresso
pressure gauge will not produce an
accurate reading if using old coffee beans.

Note: Pre-ground coffee grinds are too
coarse to use with single wall filter baskets.
Note: It is normal for the correct dose of
coffee grinds to appear overfilled in the filter
basket before tamping.
