To compensate for lower Aeration (higher %) Pre brew can be increased to a certain degree.
Increased Pre brew time means that more water and coffee are added before the plunger reaches the
top position. This produces a better blend.
Adjust Pre brew in steps of 0.1 - 0.2 sec at a time; this quickly provides results in terms of taste. Varies
for different coffee types, however.
Increased Extraction time produces more body, but only to a certain degree. Too much time makes the
coffee over-extracted, which produces a very bitter taste.
To little Extraction time means the coffee is under-extracted, leaving little aftertaste.
If you wish to cut down on the total brewing cycle time, you want the taste to undergo minimal
change. If you shorten the Extraction time, you can compensate somewhat by either putting the
grinder on a finer coarseness setting or increasing the coffee dose. You then have to test the coffee
carefully, to make sure it is not too strong. When you have tasted several cups of coffee, it is very
easy to misjudge the taste. For increased dose, the taste is very accurate when you swallow, but the
aftertaste disappears and instead it is harsh on the throat.
If you increase the volume too much, the grounds can become soaked. To fix this, you must increase
the Press time. This causes the plunger to lower more before the pause (position 3-4); the result is
a higher vacuum effect in the cylinder and more finished coffee is sucked out through grounds. At
the same time, you should increase the Decompress time, to allow the coffee to penetrate the filter
before empty position is reached and the vacuum pressure in the cylinder is released. Remember to
increase the Empty time so all the coffee can drain out of the cylinder.
For fresh brew machines, the coffee should have the coarsenessautomatic grinding. Grinder settings
for automatic grinding are: grinding blades together and set 11 steps back. The optimal total contact
time between water and coffee for automatic grinding is 30 sec. The basic settings for coffee were
defined in cooperation with ECBC in Oslo, to ensure quality in the cup.
