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: Moscato and Moscato Spumante range from dry to sweet (sweet versions need at least 9.5% vol actual alcohol), so sweetness is null; the sparkling method is not stated and sparkling winemaking may take place anywhere in Sicily. Passito uses grapes dried on the vine or after harvest. Tendone is excluded and the 4,000 vines/ha minimum applies to new vineyards.
