Author Rich Wagner has developed tours of breweries past and present for Philadelphia, Pittsburgh, the Lehigh Valley, Wilkes-Barre/Scranton and south-central Pennsylvania. His interest in breweriana led to taking a very early retirement from his teaching career in order to participate in the emerging craft brewing industry. He attended the Siebel Institute of Technology in Chicago, where he received a diploma in brewing technology and spent seven years working in Philadelphia's craft breweries. He has spent a decade as an officer of District Philadelphia, Master Brewers Association of the Americas, most of that time as secretary and membership chair. He currently spends his time researching and writing about Pennsylvania breweries and brewing techniques of antiquity. He is a public speaker and demonstrates colonial brewing.
