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: The register names “Colli Lanuvini” and “Colli Lanuvini Superiore” are taken as the bianco types; the text also governs a rosso and rosso superiore, added here. The riserva is a rosso; no grape yield or natural alcohol is set for it. Alcohol minima are given as 'complessivo' (recorded as total). The bianco and rosso may be secco or amabile and the spumante secco to dolce (sweetness null); the sparkling method is not specified. Wineries within 100 m of the zone may be allowed to vinify outside it.
