So the next step to really good beer is water quality and temperature control!


To do this a good way is to use a fridge or freezer and a temperature controller.  Fridges make excellent fermenters because you can use the light bulb to heat and the fridge element to cool. The brewpi uses a raspberrypi and an arduino.  The software is developed and all you need is the hardware and a good project box to hold it all in.  So on a visit to the London Hackspace to watch some beer being brewed I was happy to be shown how to make the box on the last cutter. Now just need a fridge, some ssrs and a temperature probe or two!

Water quality wise I have hard water… and the analysis goes on!
