FLOW RATE & GRIND SETTING
•
Ensure that your dosing and tamping is consistent.
•
Good extraction is characterised by a 5–10 second delay before
any coffee will pour. Heavy droplets will appear and develop into
a thick, straight and even pour. The colour will be dark brown or
hazelnut, preferably with a reddish reflection (see page 33).
•
The pour should be cut off before the colour lightens and the
pour begins to curl in.
•
If the flow is too fast (another sign is a pale crema and white
streaks) then adjust your grind to make it finer.
•
The finer the grind the slower the extraction. The coarser the
grind the faster the extraction.
•
If the flow rate is too slow, adjust your grind setting to make it
coarser.
•
Correct grind equals correct extraction equals correct flavour.
