Wine may only be produced from grapes grown on authorised vineyards. In particular, certain criteria must be met for the authorisation of a new area that has not previously been used for viticulture. In addition to compliance with the relevant EU regulations, this primarily concerns the climatic conditions and the suitability of the soil. The planned establishment of a vineyard or the planting of vines in compliance with all laws, observance of all criteria and the necessary measures are described under vine establishment plan.

The six factors for wine quality are Climate (micro-, macro-, meso-, topoclimate), grape variety (with regard to climate, soil type), soil type(water balance, minerality, terroir), topography(altitude, slope, proximity to water, exposure), vintage(weather conditions in the vegetation cycle) and the vinification (signature of the winemaker).
