Worked out from the boundaries (smallest container first). They follow whole communes, so a neighbour sharing a commune can show up here too.
Boundary drawn from whole communes, so it is a little larger than the legal zone. Boundary: Eurac Research PDO inventory (CC0). Country outlines: Natural Earth. Dots on the zone map are the vineyard points used for climate.

Copernicus ERA5-Land monthly averages at 5 vineyard points (Vineyard point 1, 508 m; Vineyard point 2, 505 m; Vineyard point 3, 493 m; Vineyard point 4, 527 m; Vineyard point 5, 568 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.

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: Vino de pago in Ayegui (Navarre). Yields are set per variety, not per wine: Tempranillo, Merlot and Garnacha 7 000 kg/ha (49 hl/ha), Mazuelo and Graciano 7 200 kg/ha (50.40 hl/ha), Cabernet Sauvignon 6 800 kg/ha (47.60 hl/ha), so yields are left null. Grape shares are not stated. Continuous presses are prohibited. From the Spanish technical file (Ares(2014)2102555) the lowest per-variety grape yield (Cabernet Sauvignon, 6 800 kg/ha) is recorded as max_yield_t_ha; the other varieties' limits are as listed above.
