Ampelography

Ampelography (ἄμπελος [ampelos], 'vine' + γράφος [graphos], 'writing') is the field of botany concerned with the identification and classification of grapevines, Vitis spp. Traditionally this has been done by comparing the shape and colour of the vine leaves and grape berries; more recently the study of vines has been revolutionised by DNA fingerprinting.
