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 and their areas intended to produce grapes for other purposes than table grapes or growing plants for vegetative propagation. The data concern the vine types, degree of specialization 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 and integrated with the farm register.

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, age of plants and size classes of holdings.
