Organic sparkling wines from Portugal

Biovino lists 7 wines in this category from 2 winemakers.

Every wine states which standard it is produced to – from EU organic to the Bio Suisse Bud to Demeter – and how the cellar work was done: spontaneously fermented, unfiltered, without added sulfites, vegan-fined.

The details come from research with the winemakers and their certification bodies; the ratings come from the Biovino community. If a wine is missing or a classification is wrong, both can be reported directly on the wine's page.
