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: Cabernet riserva's total alcohol minimum is misprinted as '1,50 % vol' and is not recorded. Blends (bianco, rosso, rosato, novello, spumante) take yields and natural alcohol from their component varieties; novello needs carbonic maceration of at least 40% of the grapes. Spumanti may be bottle- or tank-fermented; frizzanti and bianco/rosato/Merlot may be dry or sweeter (secco, abboccato, amabile).
