Falstaff Beer, once brewed and bottled in over ten locations around the United States, including four plants in St. Louis, has a long tradition going back to the Lemps. The old Forest Park Brewery, where the Griesedieck family began producing Falstaff after buying the brand from the Lemps during Prohibition, was one of two breweries where beer was distributed to the public after Prohibition ended. Falstaff never built a brewery in St. Louis, but bought up old defunct breweries instead.
The offices are now again a brewery called Six Row Brewery.
I never looked very closely at this building, driving by on Forest Park Avenue, but it actually is fairly interesting, and upon closer inspection had the massing and accoutrements of many other more well-known breweries in the city.
After Faltstaff began brewing beer at larger facilities, this brewery changed to a bottle shop and plant.
Forest Park Avenue has many such old industrial uses, and the Falstaff Brewery is one such great example.
Please visit this great Falstaff Beer site, where I learned most of my information about the old brewing company.
