Worked out from the boundaries (smallest container first). Uses the delimited parcels where INAO publishes them.
The delimited vineyard parcels themselves, so the shape is patchy: only land within them may grow the wine. Boundary: INAO parcel delimitation (Licence Ouverte); nearby parcels drawn as one block, with less detail for larger appellations. Country outlines: Natural Earth. Dots on the zone map are the vineyard points used for climate.

Copernicus ERA5-Land monthly averages at 5 vineyard points (Vineyard point 1, 142 m; Vineyard point 2, 23 m; Vineyard point 3, 381 m; Vineyard point 4, 370 m; Vineyard point 5, 123 m), moved to each point's height from the model's terrain. Indices that need daily data are not captured yet. How the climate figures are made.
Lower confidence:Monthly reanalysis in complex terrain (height corrections up to 2.8 °C); absolute values may be several degrees out, year-to-year changes are more reliable.
Closest climates in the database
Picked by the data, not by hand: the profiles nearest on season warmth (counted twice), degree days, rain, ripening-month nights and day–night range. Neighbours within 30 km are left out, as they share the same weather.

Seasons are labelled by harvest year (April–October). Year-to-year changes from ERA5-Land; tested against station records in Alto Adige (r = 0.94 for season temperature at Bolzano). Rain varies more locally, so treat single-season rain with some caution. Vintage ratings, harvest dates and frost or hail events have places in the data model but are not loaded yet.

- Generated from EU reference data: check against the current product specification.
- From the specification: Varietal proportions in the grape rules are set on the holding's vineyard (encépagement) except the accessory limits for reds and rosés, which apply to the blend; every wine is a blend of at least 2 varieties with the largest at most 80% of the blend. 'Côtes du Roussillon les Aspres' is listed in the register but this cahier des charges sets no rules for it, so its product is left empty (colour not stated here). Wines may carry 'primeur' or 'nouveau' (reds then max 2 g/l sugar); reds with natural alcohol above 14% may have 4 g/l sugar; irrigated parcels are limited to 7.2 t/ha; reds max 0.4 g/l malic acid.
