Quality control plays an important role in viticulture. This concerns the entire production process from vineyard care to cellar measures as well as the control of the end product through appropriate measures. The term "controlled" is understood to mean compliance with guidelines that are regularly checked by responsible state-licensed and/or private institutions or associations
Quality management (QM) basically refers to all organised measures that serve to improve products, processes or services of any kind. This includes the definition of quality requirements and inspection procedures. Quality control is the ongoing monitoring of product quality during production as part of quality assurance. According to the internationally recognised quality management standard ISO 9000, the aim is not to optimise the quality of a product, but to maintain a specified and clearly defined quality level.
