Setúbal & the peninsula
- Location: South of Lisbon, with the Atlantic to the west and the Tagus and Sado estuaries shaping the wider peninsula.
- Setúbal DO: This protected origin is reserved for fortified wines, with sweet Muscat as the key study reference.
- Wider region: Península de Setúbal IGP is a different designation that also covers still wines; the regional name alone does not mean fortified.
