Copernicus ERA5-Land monthly averages at 1 vineyard points (Vineyard point 1, 75 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:No vineyards are mapped here yet, so this is the climate at one point in the middle of the zone, which may not be where the vines are. Monthly reanalysis in complex terrain (height corrections up to 1.4 °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: Passito from grapes dried on racks in the sun or in forced-air driers, losing up to 35% of their weight; no minimum drying period. Sweetness is 'amabile o dolce', so it is left null.
