quality control

Quality control (GB)

Quality control wine Quality management (QM) basically refers to all organized measures that serve the improvement of products, processes or services of any kind. This includes the definition of the quality requirements and the test procedures. Quality control is the ongoing production-accompanying control of product quality in the context of quality assurance. According to the internationally recognized ISO 9000 quality management standard, this is not about the quality of a product, but to maintain a predetermined and clearly defined quality level.

This may also mean, if necessary, to ensure a low level of quality. The product may be both material, as well as a service provided or a procedure used. Also in viticulture quality control measures have been common for a long time, which presupposes corresponding standards. At the Spanish Rioja a document from the year 1650 already refers to a quality control.

In the winemaking the production process is not just about self-evident prerequisites like hygiene but as clearly defined, measurable criteria. The quality control begins already in the vineyard. A key point is, for example, setting the appointment for the vintage, The prerequisite for this is the best possible physiological maturity of the grapes, which is determined by different methods of measurement. There are more checkpoints during the fermentation (for example degree of conversion of sugar in alcohol ), during the removal (eg sensory Exams) and before the bottling by analytical tests (eg, determining alcohol content and total extract ).

A well-known standardized procedure is HACCP (Hazard Analysis and Critical Control Points), in which the entire manufacturing process is divided into phases, at the end of each of which a control point is defined with corresponding measurement methods. A set of rules is based on it IFS (International Featured Standards), which guarantees traceability of the production process. Such quality controls are more or less pronounced by the producer himself. The EU prescribes it Quality wine testing which are carried out by official bodies. If the result is positive, the Official test number and in Austria the State test number forgive.
