Here is some inspration. Brewers brew there own beer now you can creat your own computer controlled arduino interfaced beer brewing rig and thermostat.

[Yuri] spent some time building a computer controlled, arduino interfaced beer brewing rig. A cooler serves as a mash tun, while the arduino controls a steam source that’s used to raise the temperature of the mash as desired. A java app talks to the arduino to set the temperature parameters and monitor the steam boiler.

Sean shows us how to use an Arduino for kegerator temperature control. He discusses the home brewing process and how a microcontroller can be applied to this and many other sensing and control task.

Here is someting to dream about. NanaBrewMaster is self contained brew heaven. Got to love the clean design. Kind of looks like Ikea brewing.
