White wine grape · Vitis vinifera
A Portuguese white wine grape known for its acidity, documented across Portugal's wine regions and distinguished from the similarly named Arinto Tinto.
UC Davis FPS lists Portugal as Arinto's country of origin, white berries and wine use, with Arinto de Bucelas and Pederna among its synonyms. It explicitly says Arinto Tinto is not this variety: that name is a Portuguese synonym for Tempranillo.
Wines of Portugal describes medium-sized, compact bunches with small berries and identifies firm acidity as a characteristic. UC Davis FPS independently describes high acidity and citrus qualities in aged wines. These are attributed descriptions, not a guaranteed acidity measurement or wine result.
Wines of Portugal reports Arinto grown in most Portuguese wine regions and discusses its acidity contribution in Alentejo and Tejo, alongside its Bucelas association. That regional account does not establish heat tolerance, water requirements or suitability at another vineyard.
Reference review · November 9, 2026
Independent institutional variety record used to cross-check cultivar identity and naming. It does not independently validate every agronomic observation in Plantgrape.
Portuguese industry reference supporting regional cultivation, bunch descriptions and attributed acidity characteristics; not independent field-trial or irrigation evidence.
Cultivar descriptions are source-attributed reference material, not site prescriptions. No numeric soil-moisture threshold, disease diagnosis, regional suitability guarantee or GroundWorx performance claim is established here.
