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.

- From the specification: Varieties (9): Albillo Real, Cabernet Sauvignon, Doña Blanca – Malvasía Castellana, Garnacha Tinta, Godello, Moscatel de Grano Menudo, Palomino, Tempranillo – Tinta del País, Verdejo. Clarete and rosé wines share one set of analytical limits but have different red-grape minimums. Ageing is permitted for all types but no ageing periods are given; clarete and rosé yields follow the red and white grape-variety limits. The national technical file sets planting density between 800 and 4,500 vines per hectare.
