Tartrate: a crystallised salt, not a flaw
The standard
An explained crystal formation names tartrate for what it is, precipitated salt of the acid, rather than reading it as haze or fault.
Criteria
- The crystals consist of tartrate, not of sugar or glass
- Their precipitation follows from temperature and saturation, not from spoilage
- They are without odour or taste
- Their appearance presupposes an untreated or mildly stabilised acidity
Distinction
Tartrate ≠ tartaric acid: the tartaric acid is dissolved, the tartrate its precipitated salt. Tartrate ≠ haze: the explained crystal formation is a firm, settling deposit, not a cloud of suspended matter.
