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: Enrichment is not allowed for Vin Santo, whose grapes must reach at least 26% sugar before crushing; Vin Santo ranges from secco to dolce, so sweetness is null. The spumante ranges from dosaggio zero to dry and no method is stated; its grape yield is taken from the general 12.5 t/ha limit for «Bianco di Pitigliano», which does not name the spumante explicitly.
