In 1876, the year Budwieser, one of the most iconic American lagers was introduced, St. Louis Missouri had somewhere around 50 operating breweries. By the 1977 that number had dwindled to one: The largest brewer in the world at that point. That brewer was the company that made Budwieser, Anheuser-Busch.
Now more than 40 years later, thanks to the craft brewing movement St. Louis now boasts more breweries than it did at it's peek in the 1870's. Through interviews, and a vast trove of rare archival material, film explores the reasons why St. Louis became one of the great world capitals of beer, what happened to all those breweries. And contrasts this history with the resurgence of brewing in the city today.
