Arduino controlled brewing

This paper details experiences in making an automated brewing system. Specifically, it focusses on the initial brewing stage of mashing grains to achieve saccharification of the starches by enzymes, How can we build a system to aid brewing, specifically to control the saccharification stage? This paper provides background on temperatures used in the beer brewing process, then introduces a low-cost control architecture for automatically raising and holding temperatures, based on the Arduino. This system has been used over 50 times for a variety of beers.
