Often said to be the last large modern brewery in the US not built by a national brewing company, the mid-1970s F. & M. Schaefer brewery outside of Allentown, PA., was designed using a coolship. Later operated by Stroh, Pabst, Diageo and, today, it is the largest brewery owned by the Boston Beer Co. Said BBC executive, David Grinnell, of the facility:
"(Schaefer) made it something of a vanity project. They put a lot of money into the masonry, and a lot of little details. You can tell the brewery was designed by thoughtful lager brewers to make high-quality, consistent beers."
