Brewed my first batch today on brewery system 2.0. It was a Geary's Pale Ale clone that I have been meaning to make for a while now. All I can say is electric rocks! It's so much easier just chilling in the basement knowing that what ever temp you set is going to be maintained without any extra work. Maintained my mash temp within .4 deg for a 90 mash with no work on my part. Also boosted my efficency from about 71% to 88%. Best part is I can monitor and control it all on my iPhone/iPad.
