Pabst was one of a huge portfolio of brands bought up one by one by an investor starting in the early 70s (and ultimately the umbrella name.) As the brands were bought, their actual breweries were shut down, and production contracted out; (I think) the last actual brewery they operated was Olympia in Tumwater (IIRC sold to Miller in the 80s.) About a decade ago the whole portfolio was sold to new ownership.
