It is understood by estate wine, within a DO, that produced in a specific environment, of an extension smaller than that of a municipal area, with its own characteristics, whose name is notoriously linked to the vineyards of from which wines with spatial qualitative characteristics are obtained, and which must have the prior report of the corresponding regulatory council.

Its award, by resolution of the Minister of Agriculture, Livestock, Fisheries, Food and Natural Environment, at the proposal of the director of INCAVI,  implies the maximum recognition that can be granted to a wine or other product category  (liqueur wine , sparkling wine, quality sparkling wine – 8 Catalan DOs include this type of product in their specifications – needle wine and overripe grape wine).

The estate wine must comply with  a series of requirements, established in articles 20 to 27 of Decree 474/2004, of December 28, which develops Law 15/2002, of June 27, on wine regulation .

The  requirements  are:

1. Wine produced in a specific environment, with its own edaphic and microclimatic characteristics and which produce wines with special qualitative characteristics,

2. The name of the farm is reserved and cannot be used to designate other wines or wine products,

3. The estate wine enjoys the same protection as the DO to which it belongs,

4. The designation "estate wine" must appear on the labeling together with the name of the DO to which it belongs,

5. The owner of the vineyards must coincide with that of the winery, and the production process must be done in a winery located on the same estate or nearby.

6. The vineyards and wineries must have a minimum age of 5 years in the corresponding register of the DO, a production yield in the vineyard 15% lower than that of the variety in the DO and a higher grade from the tasting committee with respect to other wines that do not have this category,

7. Need to establish comprehensive specific traceability from production to marketing (includes for example control of farming practices, cultural practices to improve grape quality, irrigation and fertigation if applicable, pressure that do not make possible higher yields to 65 liters for every 100 kg of grapes, etc.)

8. The applicant winery must have a track record of prestige and quality in the market for a period of no less than 10 years, aging must be done in oak barrels with a maximum capacity of six hundred liters.
