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.

- Generated from EU reference data: check against the current product specification.
- From the specification: Bulgarian traditional category: guaranteed designation of origin (GNP). Oak-barrel ageing is permitted, and the traditional terms Novo, Premium oak / first fill barrel, Reserva, Special reserve, Special selection, Collection and Rozentaler may be used, but the specification gives them no ageing periods. Sugar may be up to 4 g/l, or up to 9 g/l when total acidity is no more than 2 g/l below residual sugar (recorded as the 9 g/l maximum); the limit of 9,000 kg/ha applies to all wines; the wine yield is litres per 100 kg of grapes. Training: umbrella, Moser, mid-height bilateral cordon; mixed and short pruning with up to 54 buds per vine; rows 2.0–3.4 m and vines 1.0–1.5 m apart, at most 450 vines per decare (4,500 per ha), no minimum density stated. Wines from Pamid have their own lower limits, so they are recorded as a separate red product.
