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.

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: Frizzante and novello grapes may have a natural alcohol 0.5% vol below the table values (left null here). Riserva ageing may be in wood, in which case at least two months in wood; novello must contain at least 50% carbonic-maceration wine. Vinification is also allowed anywhere in the province of Bologna; several wines may be made dry to sweet, so sweetness is null for those.
