2. Statistical presentation Top
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 a 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).

4.2. Quality management - assessment

   Grading  Comments
How would you describe the overall quality of the structural vineyard statistics?  Very good
How would you describe the relevance of the structural vineyard statistics?  Good

The data asked for is relevant. However data important for agro-environemental use is missing (slope , real area, data for measuring leaf wall area)
How would you describe the accuracy of the structural vineyard statistics?  Very good
How would you describe the comparability of the structural vineyard statistics with other agricultural statistics, e.g. FSS and Annual Crop Statistics?  Very good

In LU, the data already collected by the annual survey is not asked in the FSS. So we have no double data. In fact the remaining questions of the FSS are integrated in our annual survey in the context of the single application form.
How would you describe the coherence (over time) of the structural vineyard statistics?  Very good

Very good since 2005 (GIS control established for 100% of the vineyards since 2005)
How would you describe the coherence (across regions in your country) of the structural vineyard statistics?  Very good

1 region = Luxemburg
How would you describe the accessibility of the structural vineyard statistics?  Very good
How would you describe the clarity of the structural vineyard statistics?  Good

6.3.2. Measurement error

LU uses 2 different  measures for vineyards area:

- the real area for the IACS payments (Net area)

- the "historical" cadaster area of the parcel for calculating the yield and for Stats. This area includes sometime the area needed for turning around the tractor.

The 2 areas are cross-checked in order to detect fraud.

It is planned to abandon the cadaster area and to use the real area also for calculating the yield.

6.3.3. Non response error

In the context of vineyard data collection the non-response is understood as missing characteristics in the vineyard register

Were all characteristics mentioned in Regulation 1337/2011 Annex 2 present in the vineyard register? YES
