Quality control plays an important role in viticulture. This applies to the entire production process, from vineyard care to technical measures in the cellar, as well as the control of the end product through appropriate measures. The term "controlled" refers to compliance with guidelines that are regularly checked by state-licensed and/or private institutions or associations.

Quality management (QM) refers to all organised measures that serve to improve products, processes or services of any kind. This includes the definition of quality requirements and testing procedures. Quality control is the ongoing monitoring of product quality during production as part of quality assurance. In accordance with the ISO 9000 quality management standards, the aim is not to optimise the quality of a product, but to maintain a specified and clearly defined quality level.

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
