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

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.

Still to check (3)
- Generated from EU reference data: check against the current product specification.
- From the specification: The single document sets no analytical limits or must weights (current legislation applies). The 110 hl/ha yield may be exceeded by a further 20 % stored as surplus. Products must be made in Baden-Württemberg, Bavaria or a neighbouring state; from the 2030 vintage dry wines may no longer be sold as Prädikatswein. About 198 varieties are permitted (Accent, Acolon, Lemberger, Trollinger, Riesling and others). National specification: minimum natural alcohol and must weights vary by variety and by state (Baden-Württemberg table; Bavaria higher, e.g. Qualitätswein 7.5 %/60 °Oe, Kabinett 10.3 %/78 °Oe, Auslese 13.8 %/100 °Oe, Beerenauslese and Eiswein 17.7 %/125 °Oe); the lowest is recorded (Qualitätswein 7.0 %/57 °Oe for Riesling, Silvaner, Lemberger and Trollinger; Kabinett 9.5 %/73 °Oe; Spätlese 11.4 %/85 °Oe). Kabinett, Spätlese and Classic (red or white Qualitätswein from classic varieties, must 1 % vol above the minimum, at least 11.5 % total alcohol, residual sugar at most 15 g/l and twice the acidity) are added from the national text; Riesling-Hochgewächs needs must 1.5 % vol above the minimum. The national text allows 150 hl/ha (plus 20 %) on registered steep slopes in Baden-Württemberg, against the 110 hl/ha recorded. Sweetening only with grape must; bottle-fermented Sekt needs at least 9 months total production time, and Sekt may also be made without a second fermentation. Enrichment: Qualitätswein up to 15 % vol total; not Prädikatswein.
