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.

Copernicus ERA5-Land monthly averages at 5 vineyard points (Vineyard point 1, 52 m; Vineyard point 2, 310 m; Vineyard point 3, 20 m; Vineyard point 4, 25 m; Vineyard point 5, 270 m), moved to each point's height from the model's terrain. Indices that need daily data are not captured yet. How the climate figures are made.
Lower confidence:Monthly reanalysis in complex terrain (height corrections up to 2.2 °C); absolute values may be several degrees out, year-to-year changes are more reliable.
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: Lambrusco, Salamino and Rosso may be secco, abboccato, amabile or dolce and spumanti range from brut nature to dolce, so sweetness is left null; spumante may be made in autoclave or in bottle. Density minima for new plantings are 1,600 (single canopy) and 2,000 (split canopy) vines/ha. Novello wines need at least 50% carbonic-maceration wine; frizzante types may also be sold as partially fermented must (sweet only). Enrichment is allowed 'when permitted' with rectified or local concentrated must or cold concentration.
