Copernicus ERA5-Land monthly averages at 5 vineyard points (Vineyard point 1, 190 m; Vineyard point 2, 168 m; Vineyard point 3, 311 m; Vineyard point 4, 138 m; Vineyard point 5, 409 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 complex terrain (height corrections up to 2.9 °C); absolute values may be several degrees out, year-to-year changes are more reliable.
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.

- From the specification: Rosé and red wines; Pamid varietal wines have the lower rosé limits for alcohol and wine yield (dry extract assumed as for red wines). The traditional term Rosentaler is also allowed; oak ageing is allowed and the traditional terms Novo, Premium oak / First filling in barrel, Reserve, Special reserve, Special selection and Collection may be used, without their own limits. Sugar is up to 4 g/l, or 9 g/l when total acidity is no more than 2 g below residual sugar. Pruning allows up to 54 buds per vine; spacing 2.0–3.4 m by 1.0–1.5 m with at most 450 vines per decare (4,500/ha); no minimum density stated.
