Vine characteristics

Southwest-France origin

Plantgrape describes Cabernet franc as probably originally from the south west of France. UC Davis FPS independently includes it among the principal black grapes of Bordeaux.

Soil context

Plantgrape reports its best results generally on clay-limestone soils, with good results also possible on sandy soils in the absence of water stress. This is a reference observation, not a soil map or an irrigation rule for any specific vineyard.

Regional research context

Plantgrape describes Cabernet franc as a vigorous variety trained with moderately long pruning, or short pruning in more favorable climatic zones. UC Davis FPS traces its Bordeaux and California history. Neither source converts these descriptions into site-specific planting advice.
