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 Kamptal 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 5 vineyard points (Vineyard point 1, 255 m; Vineyard point 2, 223 m; Vineyard point 3, 334 m; Vineyard point 4, 410 m; Vineyard point 5, 217 m), moved to each point's height from the model's terrain.

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: Gebietswein, Ortswein and Riedenwein differ only in style and labelling here and share one set of limits (maximum total strength 12.5 % as published). Unfermented sugar may not exceed the titratable acidity; enrichment up to 2 % vol (2.5 % in poor years); sorbate and DMDC prohibited; from 2025 grapes must be organic or 'Sustainable Austria' certified (small-producer exemptions). 'Reserve' wines cannot be submitted for testing before 1 July of the second year after harvest. Production and bottling outside the area are allowed if notified to the regional committee. The national product specification (2011) adds a Reserve type: actual alcohol labelled as 12.0 or 12.5 % vol (13 % in exceptional years by committee decision), Reserve at least 13 % vol; enrichment up to 2 % vol (2.5 % in poor years), sweetening up to 6 g/l; the quality check number may be applied for from 1 January after the harvest. Its minimum actual alcohol of 12.0 % vol differs from the 11.5 % vol kept from the single document. The national product specification (2011) gives a maximum yield of 9,000 kg grapes or 6,750 l wine per hectare, which contradicts the 10 t/ha kept from the single document. The single document's later date for Reserve (testing from 1 July of the second year) is not in the national text, so Kamptal Reserve carries no release date.
