DLG Process-Wine

Product and process certification for wine and sparkling wine

The DLG Process-Wine is the only certification in Europe for a product-specified quality standard in wine which takes the entire operation into account. The DLG Certification System focuses on product quality throughout the entire production chain. Alongside the analytical and sensorial qualities of the wines, DLG’s testing provisions include good manufacturing practice in the field of wine growing, the careful handling of natural resources, vinification processes and the monitoring of operational facilities up until bottling, packaging and transport. Aspects of sustainability and social aspects are also taken into consideration.

The DLG Process-Wine is a guideline for the recognition of improvement potentials and the subsequent implementation of changes in production. On the back of continuous quality examinations by DLG TestService GmbH, it offers secured (traceable) and guaranteed product quality to manufacturers, distributors and consumers.
