The Detroit brewery that made Stroh's closed in the early 80's. (About the time my Grandpa had to give up beer due to diabetes... coincidence? Stroh's, Schlitz, Old Milwalkee are all the same company... until about 2000 when Pabst bought a section of the company.Schaefer has been continuously available since the original brewery closed and it's been a Pabst brand for quite a few years. Of course the current beer is an imposter, as Schaefer was one of those rare BMC beers of years gone by that always had a bit more character than some of the others.
Since Pabst re-introduced Schlitz, it makes sense that they would do Stroh's as well. Heck maybe they will come back with Schaefer as well... another brand made by the Stroh's/Schlitz/Old Milwalkee company.
The brewery that Schaefer built in Allentown, PA (which Stroh acquired and eventually wound up in Pabst hands) is now owned by Boston Brewing.
It's a very nice plant, too.
