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 determination 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. In accordance with the internationally recognized ISO 9000 quality management standard, this is not about the quality to optimize 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 material, as well as a service rendered or a procedure used. Also in viticulture quality controlling measures have been common for a long time, which presupposes corresponding standards. In 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 such as 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 measuring methods. There are more checkpoints during the fermentation (for example degree of conversion of sugar in alcohol ), during the expansion (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 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 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.
