The following description uses an example recipe. The focus is not the recipe itself, but the workflow when brewing with the Brautomat.
The mash plan is a table that is processed from top to bottom. In the example, Mash-in 50°C is the first step and WHP Hallertauer Tradition is the last step. A key property is the autonext column.
Basic Functions
Each row in the mash plan contains:
Temperature (target/setpoint)
autonext (continue automatically to next step or not)
Row buttons (left to right):
Header buttons (left to right):
new row: append a new step
Delete: clear the whole table
Reload: reload recipe from file (unsaved changes are discarded)
Database: settings, select, import, export, delete mash plans
Collapse: hide/show table
In row edit mode:
Exit: leave editor without saving row changes
Save: save row changes in table
When a brew process starts, table edit controls are hidden.
Editing the Mash Plan During Brewing
You can edit multiple rows. While edits are pending, the main save button changes from green to red.
When brew process is running:
Edit controls are hidden. Pause the process to show edit controls again:
While paused:
kettle remains temperature-controlled
power button and resume are locked while editor is active
Practical Example
If iodine test shows remaining starch, extend saccharification rest:
Edit row Saccharification 72°C
Increase duration (for example +5 min)
How autonext Works
If autonext is disabled:
at timer end, process stops at this step
user must press Play to continue
If autonext is enabled:
at timer end, Brautomat automatically switches to next step
This is especially useful after mash-out and during lautering pauses.
Autonext vs Pause
autonext disabled at step end: hob turns off
Pause button: timer pauses, hob stays active and keeps temperature
Special Function: 0°C with Autonext
Set:
Effect:
rest timer starts immediately
Typical use: post-isomerization directly after boil.
The default concept is ascending infusion. Other methods (for example decoction variants) are possible with semi-automatic operator actions. Buttons Play and Pause are used as manual triggers when needed.
Multi-Kettle Basics
Brautomat supports up to 3 kettles:
kettle 1: IDS / MAISCHE (main process kettle)
Only one active rest timer exists at a time (linked to kettle 1).
Control Commands
Command syntax in step name:
DeviceOrActuator:Power
Power can be:
Examples:
SUD:Cook partial mash (interpreted as 100%)
For actuator command steps, set temperature and duration to 0.
Special Command: Boil Transition Power (1.60+)
In addition to IDS:75, you can set boil transition power directly:
This defines fixed boil power (0..100%) after the configured boil transition temperature.
Example: IDS Power Strategy
Typical strategy:
heat with full power during ramp-up
reduce power at high temperature region to avoid boil-over
The sequence below shows changing max IDS power during process steps:
Example: Decoction with Two Hobs
IDS and SUD control command Practical pattern:
partial mash to boil in kettle 1 (MAISCHE)
remaining mash temperature hold in kettle 2 (SUD)
Example: Calculating Power by Batch Mass
If mash mass is 35kg (for example 7kg grain + 28l water), a practical estimate for ~1°C/min ramp:
So IDS:75 is a typical starting point for this setup.
Control command MAISCHE power Special Function: Profile Switch
Profile commands:
Examples:
These commands load complete kettle parameter profiles.
Note: profile switch is aborted if device type does not match (IDS1/IDS2/relay).
Example Brew Day
Two-kettle setup:
mash kettle (70l, GGM IDS2, 3.6kW)
NACHGUSS kettle (35l, 2kW)
Two actuators:
ring heater in mash kettle (3.5kW)
Mash plan example:
example mash plan brewing day The example demonstrates:
actuator switching by commands
manual/automatic transitions via autonext
combined kettle control (mash kettle + NACHGUSS)
hop timing logic from total boil time
