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.

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: Riesling is the only variety named. Quality wine needs at least 88° Oechsle or at most 7.5 g/l acidity (so no unconditional minimum must weight), with residual sugar up to 'semi-dry' up to 100° Oechsle and at most must weight/3 above. Potassium sorbate, lysozyme, dimethyl dicarbonate, electrodialysis, dealcoholisation, cation exchangers, concentration, sweetening and oak chips are not permitted; Prädikatswein may exceed 15 % total alcohol. The area lies within the PDO Mosel.
