Muenster

A pasteurized, semi-soft cow’s-milk cheese in U.S. identity — 50% fat-in-solids, 46% moisture cap — not French washed-rind Munster and not a smear.

U.S. muenster is a named mild, pasteurized cheese, not a translation of French washed-rind Munster. 21 CFR 133.160: legal names “muenster cheese” or “munster cheese”; minimum milkfat 50 percent by weight of the solids; maximum moisture 46 percent by weight; the dairy ingredients used are pasteurized 1. There is no 60-day raw-milk alternative in this standard. That is a different legal design from Cheddar. See Food safety.

The make: lactic acid-producing culture; clotting enzyme; after coagulation the mass is divided into small portions, stirred, and heated, with or without dilution with water or salt brine, to regulate whey separation; transferred to forms that drain; may be pressed and turned; then salted 1. Water or brine in the vat is a washed-curd lever, same family of moisture control as other stirred, unmatted pastes. It is not a surface smear. Optional coloring, calcium chloride at not more than 0.02 percent of the dairy ingredients, curing enzymes, surface antimycotics, and vegetable oil used as a coating for the rind are in the standard 1. An oil coat is a drying and oxygen choice, not Washed rind.

Washed-rind identity in U.S. law looks like Limburger: frequent weak-brine applications to the surface until surface-curing organisms develop 2. CDR’s smear — salt water plus bacteria and yeast rubbed on during affinage — is that job 3. Muenster’s section does not describe it. If a wheel labeled muenster smells like a washed smear, you are tasting a make or a marketing overlap, not 133.160.

FAO’s four stages still apply: coagulate, drain, salt, ripen 4. This identity is usually eaten young. Do not age it into Limburger by wishing.

What to notice

Paste: ivory to orange-tinted if colored, moist, sliceable, mild lactic. Rind: often a smooth, slightly oily skin, not a sticky orange smear. Flavor should not be aggressive. Graininess or slits are vat and drain problems. Return to Cheese.

After salting, cured with frequent applications of a weak brine solution to the surface until surface-curing organisms develop. If dairy ingredients are not pasteurized, cured at not less than 35 °F for at least 60 days.

Smear is water with diluted salt (~3–6%) plus bacteria and typically yeast. Molded-rind humidity 90–95%; aggressive smeared-rind 98%+.
