The key to Blichmann Engineering’s Tower of Power home-brewing system is its temperature control module, which monitors and adjusts the temperature of mash as it is being circulated. “Stepped mashes are as simple as dialing the Control Module up using the arrow keys and hitting enter,” contends an Aug. 31, 2012, review on the website of the Indianapolis beer and wine supply shop Great Fermentation. “Beer geeks rejoice: That 17-step mash schedule you’ve always dreamed of is now very, very doable.”
What makes the control module doable is the wire- and cable-harness manufacturer ALTEX Inc., which has built close to 5,000 controllers for Blichmann Engineering since 2012.
