We'll all be using mass produced small scale stainless fermentes like rabeb has designed. In built temp, pH and gravity sensors talking to wireless switches that turn things on and off to stay +/- 0.001% of target. Though I have an internal argument everytime I look at that type of stuff. I want the toys, but I'm only a few years into brewing and I feel there's so much to learn. I wonder whether putting the brew on software based auto-pilot may get in the way of that learning. Maybe something for later when I've got more recipes where I'm not looking to experiment.
