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: Products are the specification's quality categories (quality wine KZP, top-quality wine KZP, archive wine, the Prädikat-style late-harvest categories, top-quality sparkling and quality semi-sparkling wine); the white/rosé/red split follows the sugar-free extract table (min_dry_extract_g_l = sugar-free extract). Late-harvest categories (kasna berba, izborna berba, izborna berba bobica, izborna berba prosušenih bobica, ledeno vino) are terms of top-quality wine; their yield is assumed to be the top-quality limit; their sugar-free extract follows the top-quality values by colour; ice wine grapes must be picked at -7 °C or below. Enrichment and sweetening are allowed for quality wine (total strength raised by at most 4 % vol.) but prohibited for top-quality and late-harvest wines, as are acidification and deacidification. Archive wine must be kept at least five years, three of them in bottle. Sparkling wine cuvée min. 8.5 % vol. total and at least 3 bar; semi-sparkling base wine min. 9 % vol. total, 1–2.5 bar. No liqueur wine category. Sub-regions: Hrvatsko Podunavlje and Slavonija. Main varieties Graševina, Rajnski rizling, Chardonnay, Pinot sivi, Frankovka, Cabernet sauvignon, Merlot.
