01 · What the law says
The rules
Limits on grapes, yields, ripeness and ageing that every wine labelled Nitrianska must meet.

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: All varieties in the national register may be grown; a varietal wine ('odrodové') allows up to 15 % by weight of other varieties. Grapes for víno CHOP and akostné víno may be enriched up to 22 °NM (white) or 24 °NM (red); wines with an attribute (prívlastok) may not be enriched, so enrichment is not recorded as one value. Grapes must come entirely from the area, but processing and bottling may take place anywhere in the Slovak wine-growing region. Ice-wine grapes must be picked at -7 °C or below; liqueur wine has at most 22 % vol actual alcohol. Sekt V.O. and pestovateľský sekt may be made by primary or secondary fermentation; the method is not fixed. The yields of about 12-18 t/ha and residual sugars in section g are typical values, not limits.
