Where it is

Bramaterra in Italy

Latitude: 45.5°–45.7° N
Vineyard altitude: 284 m to 399 m
Production zone: 11,562 ha

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.

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.

Still to check (3)

Generated from EU reference data: check against the current product specification.
From the specification: Vinification, ageing and bottling are restricted to listed communes in the provinces of Vercelli and Biella. Wine output is written in litres per hectare (5.250 and 4.700 l/ha), left null. 'Vigna' wines need 12,00% vol natural alcohol; up to 15% of younger or older Bramaterra may be blended in.
