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: “Cerveteri Rosato” is listed in the register for this PDO but belongs to another denomination and is not governed by this text, so its values are null. All types may be secco, abboccato, amabile or dolce (sweetness null). The spumante may be elaborated anywhere in the province of Roma (method not specified) and the novello must be bottled by 20 December of the harvest year.
