I have been thinking about making a hopback for some upcoming beers. I might consider buying Blichmann's Hop Rocket instead given the 120v RIMS rocket adapter they are offering. This seems like an inexpensive way to manage mash temperature. Unfortunately, there seems to be very little information out there on the RIMS device.
Who has one? Has it been effective? How quickly does the temperature rise? Any quality issues? How hard is it to wire to a 3rd party PID?
