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: Vinification, drying and ageing must take place within the province of Grosseto, so vinification_in_zone_required is left null. Vin Santo may be secco (min. 12% actual alcohol) or amabile, so sweetness is null; grapes are dried to at least 26.6% sugar and aged in caratelli of at most 500 litres. Riserva requires 12% total alcohol at release. No release date is given for Vin Santo Occhio di Pernice Riserva.
