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.
01 · What the law says
The rules
Limits on grapes, yields, ripeness and ageing that every wine labelled Върбица must meet.
Other varieties allowed
Besides the main grapes, the rules allow these varieties in some wines. Grape names link where a profile exists.

Copernicus ERA5-Land monthly averages at 1 vineyard points (Vineyard point 1, 282 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:No vineyards are mapped here yet, so this is the climate at one point in the middle of the zone, which may not be where the vines are. Monthly reanalysis in complex terrain (height corrections up to 0.7 °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: Red wine only (made by the traditional red-wine method); 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.
