Cheese rind

A rind is a climate at the scale of a wheel. It is not automatically “the tasty part” or “the part you cut off.” What you do with it depends on how it was made.

FAO’s ripening stage is enzymatic change; much of that change, in surface-ripened styles, is organized at the outside ¹. CDR’s aging rooms are built to run bloomy, smeared, natural, and mixed-mold cheeses as different air problems — humidity, temperature, and airflow as process controls, not atmosphere ².

Three common strategies #

Natural rind. The paste dries at the surface. Molds and yeasts may appear; they are often brushed or left as a dry coat. The rind is a moisture throttle. Cracks mean the room was too dry or the paste was still too wet.

Bloomy rind. A white coat, classically Penicillium candida / camemberti types, with yeasts. The coat proteolyzes from the outside in, so a ripe wheel goes from chalky core to creamline. Ammonia is a late-stage smell; soapy bitterness is a paste that went too far.

Washed rind. Repeated brine or beer or wine washes select smear bacteria. Color goes from pale to orange or pink. Aroma gets savory, sometimes aggressive. The wash is a microbial choice, not a marinade for tourists.

Clothbound, waxed, and vacuumed cheeses are rind strategies too: they change oxygen and drying. They are not a fourth physics.

What to observe #

Look at evenness and whether the coat is dry or slick. Smell the cut face, not only the wrapper. Feel whether the paste under the rind is oiled, fudge-like, or still chalky. Taste paste and rind separately so you know which one you are judging.

Variables #

Humidity, airflow, turning, wash schedule, and the vat’s moisture and salt. You cannot wash a very dry cheddar into a smear-ripened cheese. The paste has to be the kind of paste that style requires ².

Affinage is the practice. Tasting cheese is how you read the result. Interior Lactic acid bacteria and surface flora are related, not identical, populations.
