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 Trebbiano/Procanico” 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. Base types of wines that also have an Amabile version are recorded as dry and the Amabile as medium; the Sangiovese Amabile uses the Sangiovese values although Art. 6 describes it only as secco, and the Canaiolo is described as amabile (sweetness left null for the base name). Expanded training systems are excluded for new plantings; vinification is also allowed in Orvieto and Vignanello by ministerial derogation.
