The standard

The microbiological stability of a wine is measured by whether these bacteria are denied the oxygen and the free access they need to grow.

Criteria

Oxygen ingress stays controlled, for without air there is no oxidation
Free sulfur effectively inhibits their growth
Completely filled vessels leave no headspace
Volatile acidity is measured, not merely smelled

Distinction

Acetic acid bacteria ≠ lactic acid bacteria: the former spoil, the latter carry out malolactic conversion. Volatile acidity ≠ character: faint traces belong to wine, their emergence shows that the microbiological stability is lost.
