Principal grape varieties
The Portuguese regulator (IVV) does not distinguish principal vs accessory varieties — every authorised casta is listed together in the caderno de especificações.
Terroir
Human factors
- Winemaking tradition dating back to the 15th–16th centuries: vines planted in basaltic stone enclosures called "curraletas", each containing 6–10 "covachos" (70 cm deep), protecting the vines from salt-laden Atlantic winds.
- The "curraletas" are built from basalt extracted from the plots themselves; their walls ("travessas") shield the vines in spring from salt-laden winds.
Product characteristics
- Minerality and salinity are defining attributes, alongside marked acidity, fruity aromas, and moderate alcohol.
- Wines made from overripe grapes display ripe fruit and stone-fruit aromas, favoured by the heat reflected off basaltic rock outcroppings.
Terroir / wine link
- Volcanic soils combined with the Atlantic influence of island geography yield the distinctive minerality and salinity characteristic of DO Biscoitos wines.
