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: Wines naming a locality (vineyard) are limited to 11.4 t/ha or 80 hl/ha of new wine on lees, need 11.7 % vol potential alcohol, manual harvest and 95 % identity of origin, and may not be sweetened. Only batch presses may be used; density and training rules apply to vineyards planted after 1 August 2010; hand harvest is required for 'főbor' and locality wines. The sparkling wines' sparkle comes from a second alcoholic fermentation but the document does not say whether in bottle or tank. Maximum volatile acidity is 18 meq/l (20 for red wine). 'Palackban érlelt' needs at least one year in bottle; 'Öreg tőkék bora' needs 85 % from vines over 40 years old. The national technical file gives grape sugar minimums of 151.5 g/l for wine and 159.9 g/l for semi-sparkling wine, none for sparkling wine.
