2.1. Data description

The vineyard data set includes data on the structure of vineyards in the European Union. It covers the holdings growing vines intended to produce grapes for other purposes than table grapes or growing plants for vegetative propagation of before mentioned vines and the area covered by these vines. The data concerns the vine types, degree of specialisation of vine-grower holdings, main varieties of grapes and age of plants. Some indicators are collected at national level, others at NUTS2 level.  The data are extracted from the vineyard register. The Member States, which have more than 500 ha of vines for other purpose than table grape production need to collect the data.

The reference year of the data described in this report is the year 2020.
2.2. Classification system

The classification system used in the vineyard data has several dimensions:  type of vineyards, degree of specialisation of the holding, main varieties (> 500 ha t national level), age of plants and size classes of holdings. More information can be found in the Handbook.
2.3. Coverage - sector

Growing of grapes for other purposes than table grapes (mainly for wine, juice, raisins) (part of NACE rev.  2 classification of A01.21: growing of grapes) and plant propagation for vines (part of NACE rev.  2 classification of A01.30: plant propagation).
2.4. Statistical concepts and definitions

Statistical characteristics of observations

Area of vineyard is the area (in hectares) of all plots or their parts on which the vineyard is planted. The basis for the figure on the area is LPIS – land parcel identification system.

Vineyard is a continuous area planted with vines, which is cultivated by the same cultivator; the area is uniformly regulated – terraced or planted in vertical inclination – and enables a single system of cultivation (paths, etc.). A vineyard can be planted with one or more vine varieties.

Varieties of vine intended for wine production (Vitis vinifera) (recommended and determined) are determined for every wine-growing region and every wine-growing district. They are divided into white and red varieties.vinifera).
Is there a national legislation covering structural vineyard statistics? NO

2.5. Statistical unit

Number of holdings growing vines intended to produce grapes for other purposes than table grapes or growing plants for vegetative propagation of before mentioned vines and the area covered by these vines in hectares.
2.6. Statistical population
