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: Only red varieties are listed (section 7), with no shares. Grape minimums are set by variety: 12.08 % vol for Cabernet Franc, Cabernet Sauvignon, Merlot and Syrah, 10.97 % vol for Kékfrankos, Kékoportó, Zweigelt and Pinot Noir. Must enrichment is prohibited except for Kékfrankos, Zweigelt, Kékoportó and Pinot Noir; red wines must be fermented on skins and matured in wooden barrels, and 'barrique' needs at least 6 months in oak. Grapes must be processed on the day of harvest. The national technical file gives grape minimums of 10.97 % vol / 17.5 °MM (Kékfrankos, Kékoportó, Zweigelt; recorded as the lowest), 11.34 % vol / 18 °MM (Pinot Noir) and 12.08 % vol / 19 °MM (Cabernet Franc, Cabernet Sauvignon, Merlot, Syrah). It states a maximum yield of 55 hl/ha, which contradicts the 63 hl/ha recorded from the single document. Syrah may only be sold blended.
