Recipes

With the Aurora it is possible to create own recipes for the extraction and strength of the coffee to
your own taste.
For example, with these recipes you can vary the contact time, the strength and the temperature
of the coffee. It is also possible to vary the dosing of water in different quantities and phases with
various intervals.
• The contact time of the water with the coffee can be influenced by making the pump dose
slowly (20ml/sec) or quickly (30ml/sec).
• The boiler temperature can be set separately for each recipe between 85°C and 97°C.
• Water dosing quantities and waiting times can be entered by means of "pre-infusion" and
different "Pulse Brew" programmes.
It is also possible to dose water outside the filter (also called bypass). This water will therefore
be mixed with the made coffee and in this way the solution and strength of the coffee can be
influenced.
All these variables have their influence on the final result.
In the machine a total of 25 recipes can be stored and each recipe can be given its own name.
Each recipe consists of 3 volumes that can be selected for making coffee. For the low version of
the Aurora also a fourth volume can be selected, being the airpot (2,2 litres).

Recipe settings

The variables that can be programmed in each recipe are:
• Coffee volume.
• The quantity of lost water in percentages (this refers to the water that remains behind in the
coffee).
• The temperature of the water.
• The pump speed with which the water is dosed on the coffee. The speed can be set
separately for the various programmes between low (20ml/sec) and high (30ml/sec).
• Pre-infusion, the first dosing programme for dosing the water on the coffee. This function is
optional and the volume can be set between 100ml and 1000ml as well as the waiting time
before the start of the next dosing.
• Various water dosing programmes PB1, PB2 and PB3 (also called the "Pulse Brew"
programmes). For these pulse brew programmes different settings can be used for the volume
and the waiting times. For each pulse brew programme 1 dosing volume can be set, but this
can be dosed several times with waiting times between the dosings.
• It is possible, though, to use other volumes between the various pulse brew programmes.
• Drip time in seconds.
The bypass is not a variable that is to be entered, but the quantity of water that is to be dosed for
this depends on the other settings. After having entered each dosing programme, the display will
show how much water will be dosed through the bypass. If another dosing programme is entered
as well, the quantity for the bypass will be adjusted again. The quantity of water for the bypass
will always be dosed during the waiting times.
Eventually, the settings mentioned above will more or less influence the taste of the coffee.
