Copernicus ERA5-Land monthly averages at 5 vineyard points (Vineyard point 1, 234 m; Vineyard point 2, 214 m; Vineyard point 3, 430 m; Vineyard point 4, 162 m; Vineyard point 5, 14 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.

Lower confidence:Monthly reanalysis in moderately complex terrain; not yet checked against a weather station.

Closest climates in the database

Picked by the data, not by hand: the profiles nearest on season warmth (counted twice), degree days, rain, ripening-month nights and day–night range. Neighbours within 30 km are left out, as they share the same weather.

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: White wine from Roditis only. The Réserve and Grande Réserve clauses mistakenly name 'Πάτρα (Anchialos)' and do not say which sweetness types they cover. Semi-dry and semi-sweet wines may be sweetened; continuous presses are banned and fermentation must stay below 20 °C. The 17.5 g/l semi-dry sugar maximum carries an unexplained footnote mark (**).
