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.

- Generated from EU reference data: check against the current product specification.
- From the specification: Section 8 lists 29 varieties, including Airén, Albariño, Bobal, Cabernet Sauvignon, Garnacha Tinta, Macabeo, Merlot, Syrah, Tempranillo – Cencibel and Verdejo; blending white and red grapes is not permitted. Yields depend on training: gobelet 10,000 kg/ha and 74 hl/ha, trellis 13,000 kg/ha and 96.2 hl/ha. Low-strength wines need only 4.5 % vol.; semi-sparkling wines need 9 % (white and rosé) or 11.5 % (red). The document gives no ageing periods for Crianza, Reserva or Gran Reserva; red wines ferment on skins for at least three days. The technical file (Spanish) adds no ageing periods; white and rosé musts ferment at up to 22 °C and reds at up to 30 °C; quality sparkling wines may be labelled Premium and Reserva.
