Copernicus ERA5-Land monthly averages at 5 vineyard points (Vineyard point 1, 27 m; Vineyard point 2, 4 m; Vineyard point 3, 250 m; Vineyard point 4, 3 m; Vineyard point 5, 30 m), moved to each point's height from the model's terrain. Indices that need daily data are not captured yet. How the climate figures are made.

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.

- From the specification: The 70 % minimum for the starred varieties (Castelão, Negra-Mole, Trincadeira; Arinto, Síria) applies to the vineyard planting (encepamento), jointly across the starred varieties. Other red varieties: Alicante-Bouschet, Aragonez, Cabernet Sauvignon, Syrah, Touriga-Nacional; other whites: Diagalves, Manteúdo, Moscatel-Graúdo, Tamarez. The yield of 60 hl/ha may be adjusted yearly by the IVV. The annex table is headed 'DO Lagos', an apparent copying slip.
