Support of Hop Stands

Hop stands or Post-Boil Hops Additions is gaining popularity along with NEIPA. It should be convenient to have a controller that can help counting time and maintaining the temperature when necessary.


The illustration shows three hop additions in two temperature sessions. Let T1=85C, T2=60C, D1=30min, D2=20min, D3=30C for better illustration.

After boiling finishes, the controller prompts for wort chilling to 85C(T1). When 85CT1 is reached, it alarms and starts the PID to control the wort at 85C(T1). After 10 minutes, the controller alarms for the addition of Hop2, and prompts for chilling after 20 minutes more.

That is a perfect way to use hop stand, and it makes it possible to calculate a more precise IBU. However, cooling wort takes time and water. Heating the to-be-cooled wort does not seems right, and the “precise” IBU is not really precise. It might make no difference between 88C and 85C. Using a range of temperature instead of a exact temperate might save time, water, and energy.


This illustration shows a more common and easy way to use hop stands. Hop1 is added when T1(90) is reached, the wort is not temperature controlled unless necessary(the lower line under T1). If the lower bound is set to 80C, the heating might never be activated if you brew indoors.

It is a little more complicated to specify a range instead of a temperature, but it provides the flexibility. By specifying the same start and keep temperature, it will be exact the first scenario.

  1. I really like the ability to set the range, as in the second alternative.
    It seems like a good alternative to just shut of the cooler when the alarm goes on and and the hops, knowing the controller will keep the temperature in +/- range. As you said, for many people brewing in room temperature the heat migth stay off all the time.
    Ps. Great work! I’m currently building my Braumeister clone with the BrewManiac.

  2. Second alternative is good enough for it’s usage.. as said post-boil heating is not really needed… last time i did hop-stand it really only lost maybe 6c during 30min.. so it’s really not much at all for me… and i should add that i don’t even have insulated kettle, just put the lid on (where there even is a cut-out for sparge arm).
