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.

Still to check (3)
- Generated from EU reference data: check against the current product specification.
- From the specification: This version of the disciplinare has no Pignoletto types (Pignoletto now has its own DOC), so the three Reno Pignoletto products are left empty. All types may be secco, abboccato, amabile or dolce, so sweetness is not recorded; sparkling and semi-sparkling types must come from natural fermentation. Vinification is also allowed across the provinces of Bologna and Modena.
