Worked out from the boundaries (smallest container first). They follow whole communes, so a neighbour sharing a commune can show up here too.
Boundary drawn from whole communes, so it is a little larger than the legal zone. Boundary: Eurac Research PDO inventory (CC0). 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: Section 7 lists only Macabeo – Viura and Tempranillo – Ull de Llebre, without shares. Quality sparkling wine may be made by the traditional method or the 'méthode ancestrale', so no single method is recorded; it has a maximum total acidity of 6 g/l. Yields apply to the white and red varieties; rosé, sparkling and sweet wines follow them. 'Rancio' liqueur wine is dry. The older national technical file gives higher minimum actual strengths than the single document (white and rosé 10 % vol, red 10.5 % vol, semi-sparkling 10 % vol); the single-document values are kept.
