I just found out about this little keg-only brewery which operated outside of Chicago, in the far northern suburbs. It opened during the war in 1942, and went out of business in 1964, after being hit (and apparently destroyed) by a tornado. Had a couple of brands: Zeman Beer, Zeman Pilsener, and Zemen Premium- at least according to online pics of old tap knobs. This was probably a 10k bbls or smaller annual operation. There is also some anecdotal evidence that it was possibly controlled by local organized crime figures from Chicago. During the 1957-59 period, Zeman Beer was also brewed and canned by the Foxhead Brewing Co of Waukesha, WI, also said to be mob-controlled. I found a photo from the late 1950's showing "Zeman Beer On Tap", on a large bar/restaurant neon sign in downtown Chicago. So they did sell it in the city. Very little else known.... anyone out there have anything?
