Who makes cooper sharp cheese?

Schreiber Foods, Inc.
Green Bay, WI

Dad used to be a foreman at one of the Cooper aging factories in Phila, PA. Back in the 50's & 60's, Cooper and Clearfield cheese was produced in Clearfield, PA and aged at various warehouses throughout PA. Don't know how they do it now, but when I was a child (brmflchten years ago), I often went down to his work and watched the different stages in the process. 25# wheels were aged over a long period, and one of Dad's jobs was to periodically take a core sample and taste it for quality.
We ALWAYS had a "cub" wheel (5#) at the house for sandwiching or snacking.
