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.

Still to check (3)
- Generated from EU reference data: check against the current product specification.
- From the specification: One product covers still white, rosé and red wines, which share the same rules (reds must complete malolactic fermentation, max 0.4 g/l malic acid; charcoal banned for rosés); the name may carry the commune of origin. Yield is set in grapes: rendement 12,400 kg/ha, butoir 15,500 kg/ha, with at most 102 litres per 160 kg; density is set by spacing (rows max 2.00 m, row plus vine spacing max 3.00 m), not vines per hectare. In the vineyard principal varieties must be at least 95% and Voltis at most 5%; wines are aged (élevage) until at least 15 August of the year after the harvest.
