5.2 - UNDERSTANDING THE BEER BREW AUTOMATIC™ BREW CONTROLLER
The Beer Brew Automatic™ has an easy to use built-in controller that has been designed to support the three phases of brewing, as
described earlier in this user manual. Each phase is completed by heating up and maintaining the temperature for a certain amount
of thime, and where each phase has a different function in the beer brewing process.
The phases are displayed as
I
(mashing),
II
(lautering) and
III
(boiling) in the brew controller display. Each phase has three
parameters that can be changed:
• Heating power (percent %)
• Target temperature (centigrades °C)
• Time (h:mm)
The brew controller has been pre-programmed with parameter values that is suitable for brewing using a single step mashing at
65°C, with the malt basket equipment setup. Each of the three phases have been set up with a duration of 60 minutes. This will be
suitable for most beer recipes where modern, well modified malts are used.
The brew controller parameter can be changed, allowing you to set different values of your choice, and according to the recipe. How
to change the parameters is described later in this user manual.
Starch conversion in the mash occurs between 55°C and 71°C. For most homebrewers, single step mashing should be performed in
the temperature range between about 63°C (more fermentable sugar, resulting in a dryer beer with a thinner body) and 68°C (less
fermentable sugar, resulting in more residual sugar and more body of the beer). The mashing temperature will normally be described
in the beer recipe.
Some brewers may want to do multi step mashing (mashing using several different temperature steps). This is possible to achieve,
but will require you to make manual adjustments to the strike and mashing temperature during the heating and mashing phase. How
to change the settings for this is described in a later chapter in this manual.
