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.

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: Products split by colour as rules differ. The 15% limit on accessory varieties (interplanted only) applies within each parcel. White wines may have 4 g/l sugars if total acidity is at least 4.13 g/l (tartaric). The 32 listed climats follow the premier cru rules but are not separate products in the register. Wood pieces prohibited; élevage at no more than 25°C.
