Untrinkbar

Untrinkbar is a German adjective meaning not drinkable; it is used to describe liquids that should not be consumed due to contamination, toxicity, or unsafe quality. The term is formed with the negating prefix un- attached to trinkbar (drinkable).

In everyday language, untrinkbar can refer to water that fails safety standards, such as groundwater contaminated with pathogens or chemicals, surface water during algal blooms, or water from a container that has spoiled. It can also describe beverages or liquids that are unsafe or unpleasant to ingest, for example spoiled milk, heavily salted or chemically altered solutions, or toxic solvents when presented in non-ingestible contexts.

Usage in official contexts: labeling on bottles or containers may specify nicht trinkbar or untrinkbar to warn consumers; in water quality reports, streams or municipal supplies failing potable water standards are described as not drinkable. In science, untrinkbar distinguishes materials intended for non-ingestion, such as laboratory reagents or industrial chemicals, from those fit for consumption. The nuance is not only safety but palatability; even if technically safe, a liquid may be considered untrinkbar due to taste, odor, or texture.

Related terms include trinkbar (drinkable) and nicht trinkbar, as well as in German broader categories like genießbar (palatable) and essbar (edible) to describe consumption suitability.
