Spanish identity
Plantgrape describes Carignan as of Spanish origin, probably from the Aragon region, and officially designated Mazuela in Spain. UC Davis FPS independently lists Spain as its country of origin, Carignane (Carignan) as its TTB-approved name, and Mazuela and Cariñena as common synonyms.
Hot, dry-site context
Plantgrape describes a fertile variety with steady, often substantial production that is well adapted to hot, dry areas with fairly poor soils such as shale, appears well adapted to windy areas, and is sometimes susceptible to potassium deficiency. These are attributed descriptions, not irrigation, fertilizer or site prescriptions.
