There are lots of cool ways to use electricity to improve your brewday. Heat sticks, Heat exchangers, and Automatic Temperature Controls can take some of the burden off of you and leave more time for quiet contemplation and drinking.
I have a partial electric brewery in that my hot liquor tank automatically heats itself to a desired level without any input from me. This is great because before that I was heating my mash and sparge water in a pot with a propane burner and then dumping it into the HLT. This became a real problem when I had kids because managing all these tasks takes a long time and is outright dangerous with curious monkeys lurking around. My setup involves a March pump, a hot water tank heating element and a Ranco temperatur conroller. I based most this off of John P Subsavages designs and I felt pretty special about myself when it was done.
“The Electric Brewery” on the other hand, is not screwing around. When I found this site (thanks Reddit) I couldn’t believe my eyes. This guy created a brilliant, beautiful brewing setup. On top of creating this masterpiece, he provides a complete parts list and how-to on his website so you could do the same. This setup and website are, in my eyes, perfection. It’s actually a little jealously inducing. Not only has this guy created a jaw-droppingly beautiful brewey AND bar. He’s done it while raising two little ones himself. Well played sir.
The overall cost of creating this system is under $6000 and that’s actually pretty great considering it’s made from all new parts, looks amazing and costs about $2 per session to brew your batch. I think with some Kickstarter funds and a Brewers license one could easily start up a Nanobrewery or small Brew On Premises business relatively easily.
