Copernicus ERA5-Land monthly averages at 5 vineyard points (Vineyard point 1, 674 m; Vineyard point 2, 35 m; Vineyard point 3, 72 m; Vineyard point 4, 62 m; Vineyard point 5, 77 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: The register's 'vino ottenuto da uve appassite' is taken to be the passito, with grapes dried naturally on the vine or on racks; enrichment is not allowed for the passito. The spumante may be secco, amabile or dolce, its method is not specified and it may be made outside the zone; yield per vine may not exceed 4 kg.
