Goat Cheese

Opened fresh goat cheese keeps about one week refrigerated. It does not freeze well.

Wrap the cut face tightly in wax paper or plastic pressed against the surface, then put the log in a covered container. Fresh chevre dries out fast and picks up refrigerator odors readily.

Aged goat cheeses — firm, rinded, cave-ripened styles — are a different proposition entirely and keep for weeks like other hard cheeses. The one-week figure applies to the soft fresh logs and tubs that most people mean by goat cheese.

Freezing crumbles the paste and makes it grainy. If you must, freeze it destined for a cooked application.

Fresh goat cheese is a lactic-set cheese: coagulated slowly, mostly by acidification from bacterial cultures rather than by large amounts of rennet. That process produces the fine, dense, crumbly paste and the bright tang that distinguishes chevre.

It also means the cheese is quite acidic — usually below pH 4.6 — which is a real safety benefit, since most foodborne pathogens cannot grow below that threshold. What acidity does not restrain is mold and yeast, both of which are entirely at home in acid conditions.

The limiting factor is moisture. Fresh goat cheese is unpressed and unaged, holding 50–60% water, which is why it keeps for a week rather than a month. Any mold means discard the whole piece — the soft body offers no resistance to filaments spreading.

One thing that is not spoilage: goat cheese naturally becomes tangier and firmer as it sits, and develops a slightly stronger "goaty" note from capric and caproic acids in the milk fat. That is normal aging.

The real signals are a slimy or wet surface, a sour smell distinct from clean tang, pink or gray discoloration, and any fuzzy growth. A firmed, slightly dried exterior on a log can be trimmed.
