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.

Still to check (3)
- Generated from EU reference data: check against the current product specification.
- From the specification: Art. 2 gives grape rules only for bianco and rosso, so the rosato has no grape rules recorded; no minimum natural alcohol is stated for the rosato. Products used to correct musts and wines must come from the appellation's registered vineyards, except rectified concentrated must. Frizzante is the bianco frizzante and Novello the rosso novello of Art. 6.
