Copernicus ERA5-Land monthly averages at 5 vineyard points (Vineyard point 1, 10 m; Vineyard point 2, 12 m; Vineyard point 3, 75 m; Vineyard point 4, 97 m; Vineyard point 5, 5 m), moved to each point's height from the model's terrain.

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.
