Not all cheese is Kosher
In order for hard cheeses, such as Cheddar, Muenster, Swiss and the like to be certified kosher, they must be produced under constant supervision. Rennet, the most commonly used coagulant, must be microbial in order to satisfy kosher requirements, and must be added by a Rabbinic supervisor. It is understandable that cheese designated for kosher use requires special conditions.
