Plantgrape provides a cultivar-level description; UC Davis traces California selections and their histories. Those records are not evidence that all selections perform identically at every vineyard.
NC State Extension lists Cabernet Sauvignon among Vitis vinifera varieties and describes it as very late harvesting in its North Carolina comparison table. That timing is a regional observation, not a universal harvest date.
Reference review · November 9, 2026
INRAE / IFV cultivar reference. Vine-trait observations belong to this reference's context; they are not universal planting or irrigation recommendations.
Independent institutional history used to cross-check cultivar identity and geographic context. It does not independently validate every agronomic observation in Plantgrape.
North Carolina regional cultivar comparison; corroborates identity and supplies the explicitly regional harvest-season observation.
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.
