Chronicling the rich history of the brewing industry in Baltimore, MD and narrated by two historians and beer enthusiasts, Maureen O'Prey and Rob Kasper, the movie takes a look at local businesses, home brewers and organizations preserving the brewing history in Baltimore. After a century of sharp decline, Union Craft Brewing opened the first production brewery in Baltimore City in nearly 30 years. Today Baltimore brewing is multi-faceted in scale from brewpubs to a regional brewing operation.
