True Münster or Muenster cheese originated in a monastery in the Alsace region of France sometime around the 7th century (by either Irish or Italian monks). Germany has adopted this French cheese as it own, and Muenster is also popular in Scandinavia.
Muenster is a semisoft cow's milk cheese with an orange colored rind. Its flavor ranges from mild when young, to quite strong for well aged cheeses.
Muenster cheese made in the U.S. (and many other countries) is a very bland cheese which has no real resemblance to Muenster made in France and Germany.
